Authenticate to the GHL Contacts API using your app’s credentials. Ensure the requested scope is set to read-only by default (contacts.readonly) and request broader permissions only when needed.
Connect Salesmsg to GHL by supplying your app client credentials, redirect URI, and securely storing access tokens. Follow OAuth best practices and rotate tokens regularly.
Endpoints: 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: fetch a contact by ID to pull basic details, then retrieve related tasks to keep task history current.
Actions: also retrieve notes, appointments, and tags to fully enrich the contact’s CRM record.
Methods: GET /contacts/:contactId and GET /contacts/:contactId/tasks
Key fields: contactId, businessId, taskId
Trigger: when a new lead is created in Salesmsg, create the corresponding contact in GHL via POST /contacts/.
Actions: attach a tag using POST /contacts/:contactId/tags to segment the contact for marketing or sales workflows.
Methods: POST /contacts/; POST /contacts/:contactId/tags
Key fields: contactId, tagId, businessId
Trigger: propagate changes from Salesmsg to GHL; mark related tasks as completed when finished.
Actions: update the contact with PUT /contacts/:contactId, complete a task with PUT /contacts/:contactId/tasks/:taskId/completed, or remove obsolete tasks with DELETE /contacts/:contactId/tasks/:taskId.
Methods: PUT /contacts/:contactId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Faster onboarding with drag-and-drop workflow mapping between the GHL Contacts API and Salesmsg.
Real-time data synchronization minimizes manual data entry and reduces errors across systems.
Scalability: reuse proven integration patterns as you add more endpoints and teams.
This glossary covers core elements and processes used in the GHL- Salesmsg integration for clarity and quick reference.
Application Programming Interface: a set of rules that lets your app communicate with GHL to read or modify data.
OAuth 2.0 is the standard authorization framework used to grant your app access to GHL resources securely.
Contact: a person or company record in GHL that can be read or updated via API calls.
Tag: a label attached to a contact to help with segmentation and filtering.
Trigger a new contact in GHL whenever a qualified lead becomes a customer in Salesmsg.
On contact creation, pull notes and tasks to populate the CRM with context.
Schedule periodic bulk syncs to update many records and apply standard tags.
Obtain GHL API credentials and authorize Salesmsg to access contacts data.
Select endpoints like GET /contacts/:contactId and POST /contacts/ to fit your workflow.
Run tests, verify mappings, and deploy with monitoring.
You can read core contact data using GET /contacts/:contactId and related resources like tasks, notes, and appointments to build a complete view of a contact. Filter by contactId or businessId to narrow results. Ensure your app requests the contacts.readonly scope for read access.
Endpoint coverage is tied to your integration needs and plan. POST /contacts/ and POST /contacts/:contactId/tags may require higher access or a specific plan. Check your developer settings in GHL for eligibility.
Use OAuth 2.0 or API key-based authentication as supported by the GHL API. Store tokens securely, rotate credentials regularly, and use least-privilege scopes. For webhooks, verify signatures.
Yes. You can query by contactId, businessId, or other fields supported by the endpoint. Use filters in your requests to narrow results.
Handle errors by inspecting HTTP status codes, error messages, and error codes from GHL. Implement retry logic with exponential backoff and provide helpful user-friendly messages.
Rate limits vary by endpoint and plan. Plan your calls, batch requests where possible, and use caching to reduce unnecessary requests.
Map fields by aligning GHL contact properties with Salesmsg fields. Use a mapping table or object to translate data types and names, then test thoroughly with sample records.
Due to high volume, we will be upgrading our server soon!
