On Integromat, all calls are asynchronous. This means you'll need 2 separate steps to generate and retrieve media content. The best way to retrieve the response is by using webhooks but as an alternative, you can Sleep the scenario to give the media some time to generate.
Note: This is generally not recommended as the delay might not be long enough for the media render to complete.
If you've already completed the API call for generating the media content, you can now establish the retrieval of the data or media URL that was generated.
Next, we add another HTTP module.
Run the scenario once to verify that the connection is complete At this point, you can add another module to your scenario to handle the data.
Note: The delay module may work as an alternative, but we'd recommend a webhook for the best.
