Use OAuth 2.0 to authorize the Contacts API within your Slack app, select scopes for read/write access, and test the connection.
Grant Slack permission to access Contacts API resources, ensure the required scopes are approved for read and write.
1) GET /contacts/:contactId; 2) GET /contacts/:contactId/tasks; 3) GET /contacts/:contactId/tasks/:taskId; 4) GET /contacts/:contactId/notes; 5) GET /contacts/:contactId/notes/:id; 6) GET /contacts/:contactId/appointments; 7) GET /contacts/; 8) GET /contacts/business/:businessId; 9) contacts.write; 10) POST /contacts/; 11) PUT /contacts/:contactId; 12) DELETE /contacts/:contactId; 13) POST /contacts/:contactId/tasks; 14) PUT /contacts/:contactId/tasks/:taskId; 15) PUT /contacts/:contactId/tasks/:taskId/completed; 16) DELETE /contacts/:contactId/tasks/:taskId; 17) POST /contacts/:contactId/tags
Trigger: When a new contact is created in Contacts API, post a summary to a Slack channel.
Actions: use GET /contacts/:contactId to pull details, then post to Slack; optionally create a task via POST /contacts/:contactId/tasks.
GET /contacts/:contactId
Key fields: contactId, name, email
Trigger: Slack user updates a contact field; sync with Contacts API.
PUT /contacts/:contactId
Key fields: contactId, updatedFields
Trigger: Slack form submission adds tags to a contact; update via POST /contacts/:contactId/tags.
POST /contacts/:contactId/tags
Key fields: contactId, tags

The Slack x Contacts API integration lets you connect Slack workflows with your Contacts data in real time. You can trigger Slack messages from contact events, push updates from Slack to Contacts API, and automate routine tasks. It’s designed to be no-code, so you can build powerful automations quickly. The integration supports a wide range of endpoints for reading and writing contact data.
For basic syncing, you’ll typically use endpoints to read contact data (GET /contacts/:contactId) and to create or update contacts (POST /contacts/ and PUT /contacts/:contactId). You can extend functionality with tasks, notes, and tags endpoints. This combination covers most common workflows without custom code.
No heavy coding is required. The platform provides a no-code builder to connect Slack events to GHL endpoints. If you need advanced logic, you can add custom steps, but many users succeed with the built-in triggers, actions, and templates.
Test the connection by creating a sample contact in Contacts API, then verify that a message appears in Slack. You can also simulate Slack form submissions and check resulting data in Contacts API to confirm fields map correctly.
You can push identifiers (contactId, name, email) and related fields to Contacts API, and you can also add or modify notes, tasks, and tags from Slack depending on the configured endpoints.
The endpoint list is provided in the Endpoint section above. It includes read and write operations for contacts, tasks, notes, appointments, and tags, along with example payloads and usage notes.
Due to high volume, we will be upgrading our server soon!
