Getting started - What are all the administration tasks / options?
An administrator has the following options/tasks to perform:
- Create User
- Add Users to Team
- Create Channel
- Add Teams to Channel
- Create/Delete Solution
- Activate/Deactivate Solution
- Create/Delete Assistant
- Generate Reports
- Add/Configure External Messengers
- Customise Bot responses/messages
- Engine configurations
Administrators can see the list of users with details such as Full name, Alias or user name and their status. Administrators can also create new users or invite them as required.
Note: Chyme is usually auto provisioned i.e. once the Administrator configures allowed email domains, anybody with a valid email in the allowed domains can sign up. Chyme can also be configured to be “administered” only wherein users can be created only by the Administrator.
A new user can be added in multiple ways:
Create user manually: Administrator has to provide the Alias or user name, First name, Last name and Email id. The user will receive an email to activate their account by clicking the verification link.
Invite People: Administrator can invite one or more users via their email ids. Users will get an invitation mail on their respective email ids and can follow the instructions to create their user accounts.
Note: When the Administrator has configured certain domains for auto provisioning, it may still be necessary to add users (such as externals, vendors etc.) who do not have email ids on the domains. It is also not desirable to allow anyone from public domains such as gmail.com to be allowed to sign up. In these cases, administrators can invite people with emails on any domain and the specified users will be able to sign up securely.
Import Users: Admin can import a .CSV formatted file to create users in bulk. This is useful when users from other systems such as MS ADS need to be imported to Chyme. Export the data into a simple csv format and then you can import into Chyme.
By selecting a user in the list, Administrators can view the details of the user. Administrators can also change the role of a user. Administrators also have access to detailed information such as the Teams the user belongs to, Channels subscribed to and their associated devices.
Team user belongs to: Shows the list of teams the user belongs to.
Channels subscribed to: Shows the list of channels to which user has subscribed and the subscription date.
Associated Devices: Shows the list of mapped devices and the last login time on that device.
A Team is usually a department or other logical grouping of users that is reflected in the organization structure. Teams can only be created by Administrators. Users cannot join or leave teams, only administrators can add/remove users from the team. A team can receive messages on the team alias or can also subscribe to other channels. Teams can subscribe to messages and alerts from multiple channels also.
Create a Team: Administrators can create the team and add users.
Subscribe to channels: A channel is a one way link. Teams which are subscribing to channels will receive the notifications which are sent in that channel. If a team wants to subscribe to a channel switch to Channels subscribed To tab in the team details screen and click on the icon in the end of that row and select a channel from that list and click on the Subscribe button.
A Channel is a means to exchange messages between Users and Assistants. There are three types of channels available in Chyme viz.
Announcement Channel: An announcement channel is a one way channel i.e only an Administrator or other authorized users can post to this channel. Note that normal users cannot respond to messages on such channels. Administrators can subscribe the teams and/or users to which these messages are posted. Users can automatically be subscribed to such channels or they can be allowed to choose. These various options allow companies to use Chyme Announcement Channels as an effective alternative or additional means to disseminate information that is typically posted on the Intranet.
Collaboration All: Any user in the domain can collaborate via this channel i.e messages can be exchanged two way between users. Administrators can configure whether users are auto subscribed or they can choose to. Additionally Administrators can also configure on whether users can unsubscribe to the channel or not.
Collaboration: This type of channel allows private communications between the members to the channel. Only members can post messages via the channel and they cannot unsubscribe either.
Solutions and Assistants
Administrators can view the list of available solutions. By default no filters are applied and all the available solutions are displayed. You can select the filter option on the top menu bar to filter the solutions. Click on a solution to Activate, Edit or Deactivate, Delete the solution. Solutions are made up of solution bundles. Bundles are a logical grouping of bots and a solution can have one or more bundles. For e.g. if a solution is in production, additional functionality can be added via a new bundle and moved to production after testing in sandbox.
Activate a solution: Click on the solution card to display the technical name of the solution, Bundle name, Associated systems and Associated Bots. You can then click on the Activate button to activate. In the first step choose an Assistant from the list or create a new assistant and map that to the solution. Then click on the next icon which contains the System Configuration. Click on it to update the associated system’s configuration and then click on Complete Activation to finish.
Edit or Deactivate a solution: If a solution is already activated and you want to edit the system configuration or deactivate the solution itself then click on the solution card and select Advanced to edit the configuration or select Deactivate to deactivate it.
Delete a solution: If a solution is no longer required, you can delete the solution. Note that an activated solution cannot be deleted and you will need to deactivate it before deleting. Click on the delete icon to delete the solution.
Advanced Bot Configurations
Bots in Chyme are individual commands or events that a Digital Assistant is aware of and interfaces with to execute your tasks. Chyme bots are of 2 types:
Command Bot: Command is basically a “Requests from a User”. Commands are typically initiated by the user via a text message. Commands are flexible and can initiate the bot and request for required data or accept the the message and input data together to process and respond with the latest info.
Event Bot: Event is an alert or notification of a change that has occurred in a backend system such as SAP or Salesforce and is posted to Chyme for action. Events are initiated by external systems via an event webhook. The event bot accepts the message and the event data to process.
Solutions are made up of Commands and Events. You can select any Command or Event and setup advanced configurations like Distribution Rule, Custom Messages, Follow Up actions etc.
How to setup Subscribers: The event bot’s response shall be published to subscribers of the event. Event subscription is done in the Chyme Digital Assistant Configuration using the web app by selecting a Digital Assistant with an activated solution. All bots (Commands and Events) are displayed and clicking on the bot will allow the advanced configuration. Additionally, the event can also choose to publish this information to other users, groups, channels and teams in Chyme. Recipients can be channels, teams or individual users. You can search for recipients and add them to the distribution rule.
How to setup Rules: Chyme supports three different types of Distribution Rule: None, Always and Conditional.
None – In case of a command setting to None means the response would only be sent to the caller or “self”. Normally you would not want the output of a command to be sent to anybody other than you but in specific cases where required please add additional subscribers or recipients. Remember setting to None for an event implies that the response will never be sent. You would choose that only if the distribution is decided programmatically in your bot implementation,
Always – This mode will send the response always to the subscribers selected. You can customize the message text and use data from the bot via parameters. You can also add Follow Up actions that will typically be displayed as smart buttons in the messenger you are using.
Conditional – This mode allows to set up responses based on the actual data that the bot has provided. You can add/define your own rule/rule-set based on the list of fields available in entity along with conditional clause and operators. For e.g. you can choose to alert Finance Assistants team when PO value is less than 1000 $ and for higher values also alert the Finance Managers. (the rule would be similar to “PO_VALUE” field, “less than” is Operator and “1000” subscribers are “Finance Assistants”). Conditional business rules allow you to configure different rules based on data and distribute them to different recipients without any development. Additionally for each rule you can also customize the message sent and the follow up actions. Optionally you can also provide a “failure” message so that the bot will let the user know about it. For e.g a user might want to retrieve details of a PO # 12345 but since her role does not allow her to view these details, a corresponding response “Sorry, you are not allowed to view that PO” can be sent.
Chyme works with users through Digital Assistants. Like human assistants, digital assistants can understand natural language and provide suitable responses. Chyme digital assistants are conversational. So digital assistants expect voice or text messages in natural language queries and provide responses as natural language text messages (can be enhanced based on the messenger’s capability) or voice.
An assistant can be created either while activating a solution or separately vua the icon in the bottom right corner in the assistants list screen. You can set an icon for the assistant (this is what all your users will see when they converse with the assistant) give an unique assistant name (lower case is recommended), description. You can optionally choose the assistant’s language if you want to fix the language that the assistant will converse in. Chyme assistants can speak any language and is explained in greater depth in the Translation section.
Note: Assistant language by default set to English. If you want the assistant to respond to multiple languages then additionally configure the translation Engineand translation API in Admin settings screen.
Click on Next to continue the assistant creation process. You can optionally enable the webchat for that assistant. Web chat allows you to embed the assistant in a web page or web app (and respond with the solution that the assistant understands to your users). Click the next button again to continue with the configuration. A list of external messengers (if available) are displayed that you can choose. If you have not already created an external messenger, just click on Create to create a new one.
You cannot delete an assistant if it’s mapped to any of the solutions. First deactivate the solution to free up the assistant and then delete the assistant.
Webhooks as the name suggests are inbound URLs that can be called by external systems to post messages or data to Chyme. Chyme supports two types of webhooks:
- Event Webhooks:
- Event webhooks are supported via the Event Bots created in the Chyme Bots Bundle
- For each system (based on system name) there is a single webhook created for all events under the system
- Event webhook is created when the Chyme Solution is activated
- Event webhook URL can be copied from the Chyme Web App->Admin Menu->Solutions->Webhooks
- External messengers call the event webhook URL to post data (data can be in any format – event bot code has to interpret the incoming data)
- Event bot associated with the event webhook gets called when the event webhook is called from the external system
- Event bot can post the event data to any users, teams or channels after processing the data
- Event webhook can contain any plain text or structured text (JSON, XML, etc.) content in the http request body
- The content if the http body is given as a String to the Event bot for processing
- Message Webhooks:
- Chyme allows messages to be posted directly to end users, teams or channels bypassing the bots
- System that requires to post a message directly has to be added to the Chyme Bots Bundle
- Create a Webhook on the system from Chyme Web App->Admin Menu->Solutions->Webhooks->Create Webhook
|Webhook Name||<Any name>|
|System||<Choose system>||Or create a system and choose|
- Enable the webhook and copy the URL
- Post messages to the webhook using the URL along with the following parameters:
|message||<message to the user>||Mandatory. Message sent to the users messenger.|
|assistant||<assistant name>||Mandatory. Assistant name on which the message is posted in the messenger.|
|recipients||<email id or channel name>||Mandatory. Recipients who should receive the message. Can be one of the following:
|data||<business entity json>||Optional. Business entity JSON that Chyme can use for short term and long term context|
- Message is posted to the recipients directly via the Chyme server
Chyme supports multiple systems such as:
- ERP – SAP ERP, SAP S/4 HANA, NetSuite etc.
- CRM – SAP CRM, SalesForce etc.
- Databases – SAP HANA, MSSQL, Oracle, MySQL
- Others – SAP Concur, Microsoft SharePoint etc.
In addition Chyme can help you build bots for any REST or SOAP based system. Given the open architecture that Chyme supports, with additional libraries you can also connect to any third party system.
Solutions in Chyme are made up of Bots that communicate with any of the supported systems to fetch, add or update information. This could be an employee creating a leave request in a HR system or approving a purchase requisition or your vendor checking an order status in your retail system.
Deploying new solutions
User can see a list of solutions which are all available. By default screen loaded with no filters so all the available solutions will be shown. User can select the filter option on the top menu bar to filter the solutions.
Public Repository option is available in Solutions that will show the list of bots which are available in the public bot store. Click on the Copy button to copy the solution to current instance and click on that solution to activate it or click on Copy and Activate to copy and activate the solution directly.
Your custom bots
Using Chyme Bots Builder and Chyme web Configuration you can build your own custom bots. Once your bot definition is deployed to Chyme User can search for deployed Solution in List. Activate the Solution and associate Assistant to it.
Activate a solution: User needs to click on the solution card then in the next window user can see the Technical name of the solution, Bundle name, Associated systems, Associated Bots. User has to click on the Activate button and choose an Assistant from the list or create a new assistant and map that to the solution. Then click on the next icon which contains the System Configuration. Click on it to update the associated system’s configuration and then click on Complete Activation to finish.
What languages can my assistant speak?
Assistants can communicate in all languages supported by Google Translation Engine (For now Chyme supports the Google Translation engine, other services are being actively considered). The primary language of development for natural language processing is English, however with the help of the translation engine assistants can speak the end users language of choice. Language is no barrier for Chyme assistants in providing relevant answers to users queries.
Chyme supports all languages. By default an assistant and user’s language is always English. To enable other language support, the translation engine need to be configured.
- In the Chyme Web app Admin Menu select Settings
- Select the Translation Engine tab
- Select the Google
- Enter the Google API Key and Save. You can retrieve a Google translation key from your Google Developer Console.
Once translation is enabled, the assistant’s language depends on how its configured:
1. Assistant’s Language – While activating the assistant if a language has been configured (and its not English), then users are expected to converse with the assistant in the configured language. Users may still key in their queries in other languages also, however all responses will always be in the assistant’s language.
2. User’s Language – A user can configure their preferred language in their profile settings. Default is always English. If an alternative language is configured, while users may key in their queries in any language the responses will always be in the user’s preferred language.
3. Language Detect – If language detection is configured, then the assistant speaks the language that the user is conversing in. If the user enters a query in German, the response will be in German. The assistant will respond in the language of your last query.
Note: Input provided to bots are never translated. For e.g. the reason for your leave request would not be translated but would be relayed exactly as you type it.
Chyme has an internal translation database. English to other language queries can be maintained here. Chyme will first look into the translation database to find corresponding english / other language queries and will query the Google translation engine only if not found.
Automatically translated queries are also saved in the database but are not “released”. Administrators can verify the translated text, make corrections and release the translations. This ensures that over time, an internal database of the most commonly used translations are available avoiding translation engine round trips and associated costs. It also ensures that translations that are not satisfactory can be manually corrected and made more conversant.
Customizing bot responses
What messages / responses can I change?
Chyme assistants respond with a number of canned messages. These can be customized to provide more random and fun messages to the users.
Bot Timeout: Sometimes the bot may not respond with the required data (due to lag in systems that are being accessed etc.) To assuage users and keep them engaged Chyme assistants respond with messages automatically. You can configure this timeout which is 15 seconds by default.
Bot Waiting for Response: At the expiry of the timeout, Chyme will send out a message to the user. This by default “Hmm. The is taking longer than usual.” This message can be customized. If multiple messages are configured then Chyme will randomly pick one making the conversation more fun. Additionally if a response is not obtained in 60 seconds, then the Chyme assistant warns the user that its giving up with a “No response received, giving up” message. This message can also be customized with a number of fun variations to keep your users engaged.
How do I add my own fun messages / responses?
You can add your own fun messages / responses in Chyme. Chyme canned responses can be configured for requesting users to wait (Taking longer than usual) or when giving up (no response received).
You can add fun messages like: “Hey, time to get a coffee while I spin the wheels” or “Hang on a sec, I know your answer is somewhere there in ether” or “Oops. Even I fail sometimes, sorry but that was too tough for me to fulfil” and many more like this.

- Notify Channel – Channel to post system notifications to
- Push Data with Notification – If user is offline, should push notifications also include the data
- Token Expiry Time – Expiry time for all tokens that are sent by Chyme server such as password reset etc.
- OAuth Server Url – OAuth server URL, you will usually not need to change this
- OAuth App Key – – OAuth App Key, you will usually not need to change this.
- OAuth App Secret – – OAuth App Secret, you will usually not need to change this.
- Allow users with these domains to sign up – Email domains that are to be permitted for automatic sign up
- Conversation Context Expiry – Advanced setting determines how long Chyme will “remember” user conversations context information
- Record Events – Advanced setting determines if events are to be recorded by Chyme. You will want to leave this enabled.
- Waiting for response warning – Timeout for waiting for response messages
- Waiting for response timeout – Timeout for giving up response messages
You can change the company logo so that your users identify with it.
Chyme uses Google Translation Engine (currently) for international language support. Translation has to be enabled in Chyme Settings else all communication is English only.
- In the Chyme web app Admin Menu select Settings
- Select the Translation Engine tab
- Select the Translation Engine as Google
- Enter the Google API Key and Save. You can get a translation key from the Google Developer Console.
If language detection is enable, the assistant will always respond in the same language that the user requested for information.
Note: You will typically not be required to change the below settings. If you need to, please take the assistance of Chyme Support to configure this.
The bots engine fulfill all the requests for data from external systems. If your Bots engine is internal to your data center and the Chyme cloud is being used for messaging, this setting needs to be configured carefully.
Chyme relies on the open source ChatScript server for NLP processing which is part of the Chyme cloud. If you need to customize the NLP and use your own install then change this accordingly. Additionally Elastic Search URL and Credentials can be configured here if you need to use your own.
