The question is, where are those stored? If you store them on e.g. Amazon S3 you can download them in a new build, but if stored on [bitrise.io](http://bitrise.io) as a build artifact then unfortunately you can’t access those right now (a build can only access its own files). That said we’re working on the API feature request, which will add functionality for this use case, feel free to vote & comment: > [@Bitrise Public API](http://discuss.bitrise.io/t/bitrise-public-api/37): > > I’d very much like an API for bitrise.

Is something like this planned? Regards, David UPDATE: We’re closing this thread as most of the requested API endpoints are available now, and it’s really hard to track which ones are still missing and what the priority of those should be. If you have any API endpoint/feature r… If you have any questions just let us know! --- _[View the full topic](https://discuss.bitrise.io/t/start-build-via-webhook/994)._
