Sorry for the lack of clarity. By product we mean white-labelling windmill, not triggering a script or flow by api.
Out of curiosity: Have you considered alternative licenses like SSPL or the Elastic license, which make a clear(er) delineation between whitelabelling/hosting vs simply using the application? I'm sure I'm not the first person to have written off Windmill because of the AGPL.
If you are using windmill as a whole, you're free to use it however you please with the AGPL but for customers with doubts, we do sell an enterprise/commercial license.
