Mattermost consultants

Q: Can I use this for two-way communication or just sending messages?

The Mattermost node in n8n is primarily for sending messages and managing channels. For two-way communication (triggering workflows when someone posts a message in Mattermost), you would pair it with a webhook trigger node and configure a Mattermost outgoing webhook or slash command. We set up both sides when clients need full two-way integration.

Q: Does this work with Mattermost Cloud or only self-hosted?

The n8n node works with both Mattermost Cloud and self-hosted instances. You just point it at your Mattermost server URL (cloud or on-premises) and provide the access token. For self-hosted instances behind a firewall, your n8n instance needs network access to the Mattermost server, which is straightforward when both are on the same internal network.

We can help you automate your business with Mattermost and hundreds of other systems to improve efficiency and productivity. Get in touch if you’d like to discuss implementing Mattermost.

About Mattermost

Mattermost is an open-source, self-hosted team messaging platform that works as an alternative to Slack. The n8n Mattermost node lets you send messages, create posts, manage channels, and react to messages programmatically from your automation workflows. If your team uses Mattermost for internal communication and you want automated notifications, alerts, or status updates posted directly into your channels, this node handles it.

The reason organisations choose Mattermost over Slack is data sovereignty — Mattermost runs on your own servers, so messages and files never leave your infrastructure. This makes it popular with government agencies, defence contractors, healthcare providers, and any organisation with strict data residency requirements. The n8n Mattermost node preserves that benefit because n8n itself can also be self-hosted, giving you a fully self-contained automation and communication stack.

At Osher Digital, we integrate Mattermost into n8n workflows as part of our system integration projects. Common use cases include posting automated deployment notifications from CI/CD pipelines, sending alert messages when monitoring systems detect issues, and routing customer support messages from external channels into internal Mattermost threads. If your team uses Mattermost and you want to pipe automated updates into it without building custom bots, the n8n node is the fastest path.

Mattermost FAQs

Frequently Asked Questions

Common questions about how Mattermost consultants can help with integration and implementation

What can the n8n Mattermost node do?

The node can send messages to channels or direct messages, create posts with rich formatting (markdown, attachments, embedded links), manage channels (create, archive, update), add and remove channel members, and react to existing messages. You can also use it to retrieve message history and channel information. Most clients use it for sending automated notifications into specific channels.

How does authentication work with Mattermost?

The n8n Mattermost node authenticates using a personal access token or a bot account token from your Mattermost server. We recommend creating a dedicated bot account for automation so messages are clearly identified as automated and the connection does not break if a team member leaves. Bot accounts also have their own permission settings, so you control exactly what the automation can and cannot do.

Can I use this for two-way communication or just sending messages?

Why would I use this instead of Mattermost’s built-in integrations?

Mattermost has its own webhook and bot framework, but n8n gives you the ability to combine Mattermost messaging with actions in dozens of other tools in a single workflow. For example, you can receive an alert from your monitoring system, check a database for context, post a formatted summary to Mattermost, and create a ticket in your project management tool — all in one automated flow.

Does this work with Mattermost Cloud or only self-hosted?

What kind of notification workflows does Osher build with this?

We build deployment notification bots that post to a DevOps channel when code is deployed, monitoring alert workflows that format and post system health warnings, daily digest bots that summarise key metrics from business dashboards, and customer support routing workflows that forward relevant external messages into internal Mattermost channels. These are part of our broader business automation services.

How it works

We work hand-in-hand with you to implement Mattermost

As Mattermost consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate Mattermost with integrate and automate 800+ tools.

Step 1

Audit Your Communication Workflows

We document which Mattermost channels your team uses, what types of notifications they currently receive (and which they are missing), and where manual status updates are being posted that could be automated. We also identify other systems that should be feeding information into Mattermost but currently are not.

Step 2

Create a Bot Account and Configure Access

We set up a dedicated Mattermost bot account with a descriptive name and avatar so automated messages are clearly distinguishable from human posts. We configure the bot’s channel memberships and permissions, generate an access token, and store it securely in your n8n credentials. This keeps the automation independent of any individual team member’s account.

Step 3

Design the Notification Workflows

We map out each automated notification — what triggers it, what data it should include, which channel it posts to, and what formatting is needed. We design message templates using Mattermost’s markdown formatting so notifications are scannable and include the right context. For critical alerts, we configure mentions to tag specific users or groups.

Step 4

Build and Connect the Workflows

We create the n8n workflows, connecting trigger sources (monitoring tools, CI/CD systems, databases, external APIs) to the Mattermost node. Each workflow includes the message formatting, channel routing, and any conditional logic needed to determine when and where to post. Error handling ensures that a failed Mattermost post does not break the upstream workflow.

Step 5

Test in a Staging Channel

We create a test channel in Mattermost and route all automated messages there during testing. We verify message formatting, timing, and content accuracy across all workflows. We also test failure scenarios — what happens when Mattermost is unreachable, when the bot token expires, or when a target channel is archived.

Step 6

Go Live and Monitor

We switch the workflows to their production channels, enable error alerting, and monitor for the first two weeks. We provide documentation on the bot account setup, channel assignments, and how to add new notification workflows in the future. If your Mattermost server is upgraded or channels are reorganised, we can update the workflows accordingly.
