Save and Activate the Scenario
After configuring Caption AI, Postmark, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking “Run once” and triggering an event to check if the Caption AI and Postmark integration works as expected. Depending on your setup, data should flow between Caption AI and Postmark (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Caption AI and Postmark
Caption AI + Postmark + Google Sheets: When a video generation request is completed in Caption AI, the resulting summary is sent via Postmark to stakeholders, and a log of the summary and related details is recorded in a Google Sheet.
Postmark + Caption AI + Slack: Upon receiving a new email in Postmark, if the email is considered urgent based on certain criteria, the email content is summarized using Caption AI, and this summary is then posted to a dedicated Slack channel for immediate attention.
