How to trigger IAM right after the user clicks the push

There’s a catch when using Canvas for triggered IAM. I’d recommend using Campaigns instead. When IAMs are triggered via Canvas from a step, they typically appear in the second session, not instantly.

Here’s a better approach:

Create a Push Campaign first.
Then, set up a separate IAM campaign triggered by the action "Opened Push from specific campaign." This ensures the IAM is shown immediately in the same session.

If you're running a broader journey in Canvas, you can still use the API Triggered Campaign step to call the IAM campaign from within the flow.
