You authenticate by obtaining an access token via OAuth 2.0 using your GHL credentials. The access token is included in the Authorization header for each request.
Key endpoints include GET /contacts/:contactId and GET /contacts/:contactId/tasks. Use POST /contacts/ to create a contact and PUT /contacts/:contactId to update.
Yes you can create a new contact by sending a POST to /contacts/ with required fields. After creation you can manage related tasks and notes.
Yes you can delete a contact via DELETE /contacts/:contactId. Consider impact on related tasks and notes.
Use POST /contacts/:contactId/notes to add notes. Retrieve them with GET /contacts/:contactId/notes to review history.
Scopes such as contacts.readonly are required for read access. Use broader write scopes for creating or updating data.
Webhooks enable real time updates from GHL to Zapier. Configure and test webhooks in GHL and map events to Zapier triggers.
