Endpoint

POST https://api.joinoverlap.com/trigger-template
This endpoint launches an Overlap clipping workflow from an existing template for a given long-form video URL.
  • You must provide companyId, workflowId, and url.
  • All other fields are optional overrides. If you include them, they override the template’s defaults for this trigger only (they do not change the saved template).
  • Override behavior: An override is only applied if the corresponding node exists in the referenced workflow. If the workflow does not include that node, the override is ignored.
The endpoint returns a triggerId which you’ll use to poll for status and retrieve generated clips.

Processing Time

  • Horizontal clips: ~3 minutes per hour of input
  • Vertical clips: ~10 minutes per hour
  • Actual duration varies depending on template configuration and video complexity.

​
Notes & Considerations

Filler words and stuttered words will be removed from the transcript and on-screen captions, without affecting the video timeline. Silences will be cut from the video entirely.
See our guide on prompting best practices. We recommend using markdown.
No! By default, we will apply all of the same styling as your configured template. For example, if you designed a template to return vertical clips with red subtitles and soft background music, then any request made with only the url parameter will include this styling.You should use the properties to override template styling, when desired. If you wanted the subtitles to be blue instead of red, then you would pass that specific attribute.
