# Integrations Overview

> Connect MessageDesk to the tools your team already uses: Grammarly for in-app spell check, Zapier for 6,000+ app automations, and webhook integrations for custom developer workflows.

# Integrations overview

MessageDesk connects to the rest of your tech stack three ways:

* **Native extensions** that work directly inside the app.
* **Zapier** for no-code automation across thousands of apps.
* **Webhooks** for custom developer integrations.

Pick the layer that fits the job, or combine them.

## Native integrations

### Grammarly

The **Grammarly browser extension** runs alongside MessageDesk and checks **spelling, grammar, and tone** as you compose messages, comments, and templates. It's the lightest-weight way to keep customer-facing texts on-brand without leaving the inbox. Works in any browser where Grammarly is installed; no MessageDesk-side configuration required.

## Automation platform

### Zapier

[**Zapier**](https://zapier.com) connects MessageDesk to **6,000+ apps** through no-code **triggers** and **actions**. Use it to:

* Push new MessageDesk messages into your CRM.
* Send appointment reminders from your calendar.
* Post notifications to Slack or Teams.
* Kick off SMS confirmations after a payment or form submission.

No code required. MessageDesk publishes triggers like **Message Received** and **Message Sent**, and actions like **Create or Update Contact**, **Send Message**, and **Create Comment**.

## Developer and webhook integrations

### Send Webhook (custom endpoint)

For developer-built integrations, or any system that doesn't have a Zapier connector, use the **Send Webhook** Relay action to push MessageDesk events to **any HTTPS endpoint** you control. Each event is signed with an `X-MessageDesk-Signature` header so you can verify authenticity. This is the right tier for streaming events into a data warehouse, custom CRM, internal microservice, or a serverless function.

* [Send Webhook (Relay action)](/relays/webhooks): payload format, headers, signature validation, retry behavior
* [Developer Tools (Settings)](/settings/workspace-settings/developer-tools): configure your webhook endpoint URL and signing secret

<Note>
  Webhook delivery requires a configured endpoint and signing secret in **Settings → Developer Tools**. Set those up before turning on a `Send Webhook` Relay.
</Note>

## Lightweight in-app lookups

<Note>
  The **Contact Create Form** in MessageDesk also includes **HubSpot** and **Close CRM** lookup buttons: lightweight one-click integrations that pull contact details from those CRMs into a new MessageDesk contact record. They aren't full sync integrations. For full bi-directional CRM sync, use [Zapier](/integrations/zapier) or a webhook-based pipeline.
