Mattermost notifications
Before you start
- Enable bot accounts on your Mattermost server and create a bot with an access token.
- Add the bot to the destination channel and copy the channel ID.
- Enter the server origin including an installation subpath, if present. Do not append /api/v4/posts. This integration uses API v4 and only posts messages.
The server must be reachable from CertOne over the public internet. Private-network, localhost and reserved addresses are not supported. Use the final server URL directly; redirects are not followed.
Configuration
| Field | Required | Default |
|---|---|---|
| Server URL | Yes | — |
| Bot token | Yes | — |
| Channel ID | Yes | — |
Test and enable
- In CertOne, add a notification target and choose this channel.
- Fill in the configuration and send a test message.
- Check that the message arrived at the intended destination, then save the target.
- Select the saved target in the settings for the notification events you need.
A successful API response means the service accepted the request. It does not prove that the final client or mailbox received it. If a request times out, delivery may already have occurred; check the destination before retrying.
Long messages are shortened to fit the channel limit and include a link to the console for full details.
Troubleshooting
- Use the server origin (including any installation subpath), without /api/v4/posts. Enable a bot account and add it to the destination channel. Requires Mattermost API v4.
- Check token permissions, account quota, destination ID and server reachability.
- Sensitive credentials are not included in returned error messages.
