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. You keep customer-facing texts on-brand without leaving the Inbox. It works in any browser where Grammarly is installed. No MessageDesk-side configuration required. → Grammarly

Automation platform

​
Zapier

Zapier connects MessageDesk to 9,000+ apps through no-code triggers, actions, and searches. Use it to:
  • Push new MessageDesk messages into your CRM.
  • Send appointment reminders from your calendar.
  • Text someone back after they call your number.
  • Keep contacts and opt-outs in sync both directions.
  • Post notifications to Slack or Teams.
  • Kick off SMS confirmations after a payment or form submission.
No code required. MessageDesk publishes triggers for messages, contacts, opt-outs, calls, and comments. Actions cover Send Message, Send Group Message, Send Broadcast Message, Create or Update Contact, Create Comment, and Create Opt Out. Two searches let you find or create a contact or conversation mid-Zap. → Zapier

​
Developer and webhook integrations

​
Send Webhook (custom endpoint)

For developer-built integrations, or any system without a Zapier connector, use the Send Webhook Relay action to push MessageDesk events to any HTTPS endpoint you control. MessageDesk signs each event with an X-MessageDesk-Signature header so you can verify authenticity. Pick this tier when you’re streaming events into a data warehouse, custom CRM, internal microservice, or a serverless function.
Webhook delivery requires a configured endpoint and signing secret in Settings → Developer Tools. Set those up before turning on a Send Webhook Relay.

​
Lightweight in-app lookups

The Contact Create Form in MessageDesk also includes HubSpot and Close CRM lookup buttons. One click pulls 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 or a webhook-based pipeline.
