Hi @thread,

Please make sure to check the related docs at: [https://devcenter.bitrise.io/api/v0.1/#post-appsapp-slugbuilds](https://devcenter.bitrise.io/api/v0.1/#post-appsapp-slugbuilds)

If you’d have any questions or if that wouldn’t work please let us know, but also share a bit more about what you use and how you use it, e.g. the exact `curl` call or command you use for triggering the build (with the sensitive parameters removed of course).

I’ll also move this thread into #issues:website-issues as this isn’t a generic #question-answer type of topic 🙂
