Is there any way to configure sending the assembly notification to the chat mattermost?
We don’t have a step for that right now, so I’d suggest you to check the mattermost docs and see how you can send a message via
curl or similar - you can do that with a Script step.
The related mattermost docs seem to be: https://docs.mattermost.com/developer/webhooks-incoming.html
You can also create a Bitrise Step for it if you’re up to working on it: http://devcenter.bitrise.io/bitrise-cli/create-your-own-step/ - we’re of course happy to answer any step dev related questions!
Or, if you don’t have time to create a step yourself feel free to request that in the #feature-request category!
We’re also happy to answer any questions you might have!
