Within the campaign / broadcast editor drag the webhook workflow item.
Select the newly dragged webhook item, edit the name to something recognizable Ex: Send In-App Message and select Add Request
Update the following details
Add 2 new headers called X-Bourbon-Organization-Id and X-Gist-Service-Key.
The organization id value can be fetched from the integrations section within Gist web app.
In order to have full control over where messages can be queued from, let's create a new Service Key and call it Customer.io. Doing so will give you the possibility to revoke keys whenever they are not used anymore.
To trigger a simple in-app message you can use the following snippet:
Replace the-message-id with your message id. This can be fetched from the message settings screen. Note that the above snippet assumes that you'll be using the customer id as a unique identifier.
To test that everything is working properly, try sending a test.
Once you're happy with the result.
Gist gives you the possibility to include additional information within your in-app messages. The full documentation about the Gist webhook can be found here.
If you have any additional questions or need help setting up please let us know.
