To access data, you’ll first authorize the GHL Contacts API from Sequel-io, request the scopes you need (readonly for most reads), and securely store the access token.
In Sequel-io, connect your GHL account to grant Sequel-io permission to read contacts, notes, tasks, and more via the API.
GET /contacts/:contactId (single contact); GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId; GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id; GET /contacts/:contactId/appointments; GET /contacts/; GET /contacts/business/:businessId; contacts.write; POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/tags
Trigger: on demand or when a contact is updated in GHL
Actions: fetch GET /contacts/:contactId and retrieve related tasks, notes, and a compact summary
Methods: GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes
Key fields: contactId, name, email, phone
Trigger: when a contact changes, schedule a batch sync
Actions: GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes; update local records as needed
Methods: GET for tasks and notes; optional POST/PUT for updates
Key fields: taskId, noteId, status, content
Trigger: tag changes or contact updates in GHL
Actions: POST /contacts/:contactId/tags; PUT /contacts/:contactId to update core fields
Methods: POST /contacts/:contactId/tags; PUT /contacts/:contactId
Key fields: contactId, tags, name, email

The GHL API is the programmable interface used to access contacts, tasks, notes, and more from the platform.
Specific API routes like GET /contacts/:contactId and POST /contacts/:contactId/tasks that perform actions on data.
The standard authorization framework used to grant Sequel-io access to GHL data securely.
The data structure sent in requests and responses when calling the API.
Automatically create a contact in Sequel-io when a new contact is added in GHL.
Create tasks in Sequel-io when notes are added, ensuring timely follow-ups.
Sync changes instantly to keep Sequel-io data aligned with GHL.
Obtain OAuth credentials and configure Sequel-io to request access to Contacts data.
Define how Sequel-io will call endpoints such as GET /contacts/:contactId and POST /contacts.
Run test syncs, verify data mapping, and deploy to production.
You can access contacts, tasks, notes, and appointments via read operations using the Contacts API. If you enable write permissions, you can also create, update, and delete records. Access is controlled by OAuth scopes, so you can tailor what Sequel-io can read or modify. Always start with readonly access and increase permissions as needed. Regularly review tokens and scopes to maintain security.
No heavy coding is required. Sequel-io provides a no-code integration path with prebuilt connectors and field mapping. Advanced users can customize mappings or add webhooks for real-time updates. You can test in a sandbox environment before going live.
Supported methods include GET for retrieving contacts, tasks, notes, and appointments; POST for creating contacts or tags; PUT for updates; and DELETE for removals. Use the endpoints listed in the Endpoints Overview to build your flows.
Field mapping involves aligning GHL contact fields (name, email, phone) with Sequel-io fields. Use the mapping UI to choose source and destination fields, and define when each field should sync (on create, on update, or on a schedule).
Yes. You can create and update contacts and related data such as tasks and tags from Sequel-io using the appropriate endpoints. Ensure you have write access and map the required fields to reflect changes in both systems.
Errors are returned with standard HTTP status codes. Implement retry logic on transient failures and log errors for troubleshooting. Use backoff strategies and verify token validity if you encounter authorization errors.
The API endpoint list and full documentation are available in the Endpoints Overview section and the official API reference. You can also access built-in docs within Sequel-io’s integration editor for quick setup.
Due to high volume, we will be upgrading our server soon!
