Extension Incoming Webhook Handler

Integration with external applications can be done with the help of incoming webhook APIs. An extension token or ZAPI key generated by each user interacting with the extension, should be used for handling incoming webhooks and messaging apis. You will get the below given list of attributes when the extension's incoming webhook handler is executed:

User Scenario

Let us consider an extension integrating GitLab and Cliq.  The installation validator authorizes the user to install the extension upon checking if they have an account in GitLab. The handler is triggered to activate the installed extension.  Following this installation and activation, the extension's webhook endpoints are configured by through a slash command. 

Setting up webhooks in the GitLab for Cliq Extension

Create a slash command to configure webhooks for all your GitLab projects. Executing the command will return the token generation button as response. On clicking this button, each user will generate an extension token (ZAPI Key). The function associated with this button will register the webhooks for all GitLab projects present in your account.

Extension Incoming Webhook Endpoint Workflow

The custom callbacks directed to the extension's incoming webhook endpoint should be handled in the extension's incoming webhook handler. The JSON response from the third party application will be passed as headers, parameters or in the body attribute. In this example, the response is available in the body parameter. The extension's webhook endpoint is called for any event update or change made in a GitLab project. According to the response received, a message is configured and posted to a channel of your choice.
