How to integrate Mattermost in automation workflow?

3 simple steps to make your Mattermost connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.

STEP 1

Select Mattermost in workflow

Pick Mattermost app in the workflow builder [4] - just one click to select the app.

STEP 2

Connect Mattermost

When prompted, authorize access to Mattermost in WEXTL once. Mattermost credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].

WEXTL wants to integrate with your Mattermost account. Approve?

STEP 3

Build a workflow

Build your workflow with Mattermost yourself or with WEXTL® AI Builder. Connect Mattermost to any available integrations [5], or use HTTP node to go beyond them.

Mattermost

How Mattermost connects and integrates with WEXTL

Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Mattermost app is called in workflows. That allows your communication automations to run without your attention, per defined schedule [7]. Explore documentation [6] for a detailed list of fields that Mattermost supports.

Full Mattermost API documentation

The following table illustrates what fields Mattermost integration require during authorization flow inside our workflow builder [4].

Demonstration of Mattermost connection step inside WEXTL Workflow Builder [4].

Field	Type	Help
HostingRequired	select	Mattermost Cloud or your own server.
Cloud workspace URL	text	https://your-workspace.cloud.mattermost.com — no trailing slash.
Server base URL	text	https://mattermost.example.com — no /api/v4 and no trailing slash.
Personal Access TokenRequired	password	Create one under Profile → Security → Personal Access Tokens. Your admin must enable personal access tokens first.

Connect Mattermost to popular apps on WEXTL

Enter a name of the other app you want to sync with Mattermost below. Click on selected app to explore integration options with Mattermost. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.

Example automation with Mattermost integration

Select Watch New Post in Channel trigger from Mattermost - this will be a starting point in your automation. Whenever event happens in Mattermost, workflow will start [7] from Watch New Post in Channel node.

Search for Add User to Channel, connect it as the next step of integration sequence. You can use filters between Watch New Post in Channel and Add User to Channel, so only important data pass from Watch New Post in Channel to the next step. WEXTL gives you full control over the process of Mattermost automation. All parts of workflow are visible on the canvas [4].

Mattermost on WEXTL has 148 modules for combining communication automations. Explore Mattermost documentation for more.

Frequently asked questions

Common questions about automating Mattermost in your workflows.

Mattermost has 2 triggers, including "Watch New Message (Keyword)" and "Watch New Post in Channel". Triggers are start points of the workflow, and automations may start from them.

Integration has 146 actions, including "Autocomplete Custom Emoji", "Autocomplete Users", and "Get All Channels", and more. Refer to our Mattermost Documentation for detailed inputs and outputs.

No. Most automations are built visually on the canvas by picking triggers, actions, and mapping fields. You can add custom JavaScript with Functions when advanced logic is needed — but our customers do that in rare cases [4].

Yes. Connections are authenticated per account, credentials are encrypted at rest, and you can enforce approvals and team-level access controls on any automation.

The Mattermost integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Mattermost official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.

Absolutely. Where Mattermost provides native webhooks, you can use instant triggers to eliminate polling delay. For custom webhooks, WEXTL offers Custom Webhook node, so you can start automation whenever Mattermost or any other service sends event to webhook URL.

WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes for Mattermost inside the workflow builder [4]. You can also use built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) in pair with Mattermost modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
