Save and Activate the Scenario
After configuring HeyGen, OpenAI GPT Assistants, 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 HeyGen and OpenAI GPT Assistants integration works as expected. Depending on your setup, data should flow between HeyGen and OpenAI GPT Assistants (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect HeyGen and OpenAI GPT Assistants
HeyGen + OpenAI GPT Assistants + Google Sheets: When a new video script is created in HeyGen, it's sent to an OpenAI GPT Assistant for analysis. The results of this analysis, along with the video script details, are then logged in a Google Sheet for performance tracking and future reference.
OpenAI GPT Assistants + HeyGen + Slack: When a run is completed in OpenAI GPT Assistants, the last message is taken, summarized, and a HeyGen video update is created using that summary. The HeyGen video is then sent to a Slack channel for team updates.
