M-O Bot only runs for explicitly enabled projects. Ask @goulinkh on Mattermost for the webhook secret and project access before continuing.

Setup

  1. Navigate to your repository's webhook settings
    https://code.launchpad.net/~<user>/<project>/+git/<repo>/+webhooks
    Example: https://code.launchpad.net/~goulinkh/git-goulin-project/+git/git-goulin-project/+webhooks
  2. Add a webhook with this endpoint
    https://mobot.staging.launchpad.net/api/webhooks/launchpad
  3. Select the event type
    Choose Merge proposal from the event list.
  4. Add the webhook secret
    Paste the secret from Mattermost into Launchpad's secret field so deliveries can be verified.
  5. Save the webhook and request a review
    Post @mobot review on a merge proposal after the webhook is active.
