Catalyst Type Extension

Catalyst Integration in Cliq allows you to integrate Cliq components with Catalyst for custom-built coding functions that contain the intense business logic of a Cliq Extension. By integrating catalyst with Cliq, you can code your business logic of any development platform that is supported via Catalyst, in Java or Node.js platform. When a particular feature is accessed in the external service, Catalyst automatically invokes the execution of the Integration function coded in Catalyst through an HTTP call.

Catalyst Integration Functions can bundle the following Cliq internal tools: 

• Bots: Conversational interface that handles tasks or responds to queries
• Commands: Slash commands that perform custom actions
• Message Actions: Actions that are performed as the response to individual messages
• Widgets: Enables you to customize your Cliq home screen
• Functions: Custom functions that can execute tasks based on event occurrences

You can learn more about these internal tools and extensions from the Cliq developer documentation.

 Creating a project in Catalyst 

To create a project in Catalyst navigate to https://cliq.zoho.com/developer.

• Click on Create Extension button.
• Enter the name and the description of the project.
• Select execution type as Catalyst Function.
• Click on Create Project. Clicking on it will navigate you to the catalyst project page, where you can create a new project.

Creating a function in Catalyst

• To create a function enter the name and the description of the extension you want to create.
• Select execution type as Catalyst Function.
• Select a project from the project dropdown or create a new project by clicking on Create project.
• Click on Create Function, once you click on it, you will see a popup with the necessary CLI command to initialize a Catalyst Function.
• You can create a function either by executing this command line in the terminal or by accessing your project and selecting Functions, present under COMPUTE in the left-hand side menu.
• Click on Create Function.
• Select function type as Integration.
• Select Zoho Cliq as a service.
• Choose your preferred stack.
• Click Create.

 Integrating Catalyst with Cliq 

• Once you have created a project and a function, add the required components by clicking on the + icon.
• Activate or deactivate the installation flow as per your requirement.
• Click on Create Extension.

This will integrate Catalyst with Cliq and enable the Integration function to be executed each time Cliq components bundled with the extensions are accessed.

Catalyst configuration :

catalyst-config.json will be used to associate the Cliq handler with the Catalyst executor class/function.
