The notification template automation data pop-up will show you all the necessary information to trigger the notification with Integromat.

Choose HTTP as the action module of your Integromat scenario. Choose Make a request in the modules's actions menu.

The URL for the request will always be https://api.gleebeam.com/v1/trigger. Set the Method to POST. Set Body type to Application/x-www-form-urlencoded.

Choose Add item to add the necessary JSON data to the request displayed on Gleebeam in Step 1. Enter notification_id as the key and your notification's ID as the value.
In the example above I'm triggering a Gleebeam notification every time I complete a task on Basecamp. I want the title of the task to show up in every notification so I've created a dynamic field for it in the Gleebeam editor. I've named it "task-title" and, as you can see in the screenshot below, it appears in the notification automation pop-up.

To pass a custom value to it with Integromat, go back your web request's settings and add a New item to the request's Fields. Set the key to your dynamic field's name ("task-title" in my case) and the value to whatever value you want to pass from your trigger module - in my case I'm picking the recording title, which is going to be my task's title.
