# Mattermost integrations: posts and channels

> Create a post and create a channel in Mattermost, and start a workflow when Mattermost sends “Message posted in a channel”.

**Canonical page:** https://tray.ai/connectors/mattermost-integrations/
**Categories:** Communication
**Connects through:** HTTP Connector

## Overview

Mattermost is a team messaging platform with channels, threaded posts, bots, and webhook integrations that organizations can run on their own servers. Tray.ai connects to Mattermost through the HTTP Connector, so your workflows can call the Mattermost API alongside the rest of your stack.

## Use cases

### Posts

Read, create, update, delete, and manage posts in Mattermost from any Tray.ai workflow. The Mattermost API covers calls such as create a post and edit a post.

- Create a post
- Edit a post
- Delete a post

### Channels

Read, create, and delete channels in Mattermost from any Tray.ai workflow. The Mattermost API covers calls such as create a channel and list channels.

- Create a channel
- List channels
- Archive a channel

### Users

Read, create, and update users in Mattermost from any Tray.ai workflow. The Mattermost API covers calls such as search users and create a user.

- Search users
- Create a user
- Deactivate a user

### Mattermost events

Start a Tray.ai workflow the moment something happens in Mattermost. Mattermost sends events such as message posted in a channel and message matches a trigger word to a Tray.ai webhook trigger.

- Message posted in a channel
- Message matches a trigger word

## Challenges Tray.ai solves

### Keeping Mattermost credentials out of logs

A raw API call usually means pasting a key or token into the request, where it ends up in step inputs, logs, and screenshots.

**How Tray.ai helps:** Store Mattermost credentials once as a Tray.ai authentication and reference them from the HTTP Connector. Tray.ai masks authentication values in logs, so the secret never shows up in a step's input or output.

### Going from the Mattermost API docs to a working call

Translating an example request from API docs into a workflow step means copying the method, URL, headers, and body by hand.

**How Tray.ai helps:** Paste a cURL example from the Mattermost API docs into the HTTP Connector and Tray.ai fills in the method, URL, headers, and body for you.

### Handling files and non-JSON responses

Not every API answers in JSON. Some return XML, files, or binary data, or expect a multipart upload.

**How Tray.ai helps:** The HTTP Connector parses JSON and XML responses, returns files you can pass to the next step, and sends multipart form data for uploads.

## Frequently asked questions

### Does Tray.ai connect to Mattermost?

Yes. Tray.ai connects to Mattermost through the HTTP Connector, which calls the Mattermost API directly. Any call the Mattermost API documents can run as a step in a Tray.ai workflow.

### How does Tray.ai authenticate with Mattermost?

The Mattermost API uses a bearer token. You save it once as a Tray.ai authentication, and the HTTP Connector adds it to every request.

### Can I get a dedicated Mattermost connector?

Mattermost runs through the HTTP Connector rather than a dedicated connector. If your team wants one, the Tray.ai connector SDK can build a dedicated Mattermost connector from the Mattermost API.
