Authenticate requests to the Contacts API using a Bearer token obtained via OAuth 2.0 or an API key. Include the token in the Authorization header and scope it to contacts.readonly unless you need write access.
Register your app in the GHL developer portal, obtain client credentials, set the redirect URL, and request the appropriate scopes. Store credentials securely and rotate keys regularly.
GET /contacts/:contactId; 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; 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

GET /contacts/:contactId
Key fields: id, firstName, lastName, email, phone, customFields
Trigger: update to pull latest tasks for the contact.
Actions: retrieve task list with id, title, status, due date and assign to app.
GET /contacts/:contactId/tasks
Fields: taskId, title, status, due, priority
Trigger: notes are added or updated.
Actions: fetch notes with id, content, createdAt and updatedAt.
GET /contacts/:contactId/notes

No heavy coding is required. The Push by Techulus platform provides visual mapping and ready-made templates to connect to the GHL Contacts API. For more complex workflows, you can add lightweight scripts or use webhooks to customize data flow. This makes it accessible for teams without a dedicated developer.
The Contacts API gives you read access to core contact fields, tasks, notes, and appointments. Depending on your app’s scope, you may access related business data and tags. Always respect the Scope: contacts.readonly unless you request additional permissions.
GHL uses OAuth 2.0 access tokens and secure headers to protect data in transit. Store tokens securely, rotate keys, and follow best practices for API security, including least-privilege scopes and rate limit handling.
Write access requires additional permissions and a higher scope. If enabled, you can create or update contacts and tasks from Push by Techulus by using endpoints such as POST /contacts/ and PUT /contacts/:contactId. Ensure your app has proper validation and error handling.
The read-only scope (contacts.readonly) restricts modifications. However, endpoints exist for writing (POST, PUT, DELETE) if you request the necessary scopes and approvals from your GHL admin. Use with care.
Test the integration in a sandbox or staging environment. Use sample test data, monitor the request/response payloads, check authentication, and verify field mappings. Slack or email alerts can help notify your team of failures.
Rate limits vary by plan and endpoint. Refer to your GHL developer docs for current quotas. Implement exponential backoff and retries, and log any 429 responses for diagnosing issues.
Due to high volume, we will be upgrading our server soon!
