Renovate: [feat] Possibility to notify about PR/MR creation via webhook (i.e. slack)

[grzesuav]

What would you like Renovate to be able to do?
I would like to have possibility to configure renovate to notify on slack when PR/MR is created.

Describe the solution you'd like
Possibility to configure :

• webhook url
• secret in configuration file // env variable ? - not sure how it could be handled
• message template

Describe alternatives you've considered
Notifications via email/reviewer - slack would fit better in my workflow.

@grzesuav would linking to documentation how to integrate GitHub/GitLab/BitBucket with Slack address your use case?
https://slack.github.com
https://confluence.atlassian.com/bitbucket/bitbucket-cloud-for-slack-945096776.html
https://docs.gitlab.com/ee/user/project/integrations/slack.html

Or is there some renovate specific information that would be posted to Slack? (if so, what would that info be?)

[grzesuav]

@ChristianMurphy I know about gitlab/slack integration, however :

• once enabled, it notifies about every MR even, like creation, merge, closed etc - this is too much spam
• I would like to be notified only about renovate MR's, there is no possibility to configure it with existing apis (to limit MR events to specific author etc)

I think that providing a flexible way to configure webhooks for select events is a nice feature idea, although it’s a feature that could get quite complex quickly, Eg:

• which events can trigger a webhooks
• multiple webhook receivers
• auth for webhooks

If there’s any other service with a similar approach to webhook configuration then it would certainly help to lock down requirements here.

• Multiple events can trigger webhooks, Eg PR creation, PR updates, automerges, vulnerability PR creation, etc
• each event can have more than one webhook receiver
• presumably need configurable get vs post
• need a configurable JSON body (eg field names, values)
