How do I connect Mattermost to Krevaya?

Paste a webhook URL. About a minute, once.

  1. In Mattermost, open Integrations → Incoming Webhooks → Add Incoming Webhook, pick the channel, and copy the URL.
  2. Paste it into Krevaya's Connections. Krevaya checks it is a Mattermost webhook address (…/hooks/…) and stores it encrypted.
  3. Delete the webhook in Mattermost any time and the connection stops.
  4. Write a post, or let Krevaya draft one, approve it in the review queue, and give it a time. It publishes in your Mattermost channel at that time.

What the review card asks for on Mattermost

Every post is one card in the review queue. Besides the copy and the media, Mattermost posts carry these choices, and a post missing a required one waits rather than guessing.

Choices on the card

  • Nothing beyond the copy and the media: approve and go.

Limits

  • Five pictures per post.
