To authorize requests to the Contacts API, use your GHL credentials: an API key or OAuth 2.0 flow. Keep tokens secure and grant only the access you need (readonly for most reads, write for updates).
Configure SimplyBook-me to use the GHL OAuth app or API key. In Zapier, connect the GHL integration and authenticate with your credentials, then map fields between SimplyBook-me and GHL.
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 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: a new booking or contact in SimplyBook-me creates or updates a contact in GHL.
Actions: upsert contact in GHL, mapping name, email, phone, and linking to related tasks or notes as needed.
POST /contacts/ (to create) and PUT /contacts/:contactId (to update) as required.
Key fields: email, name, phone, and external_id for id mapping.
Trigger: a new or updated task in SimplyBook-me affects the linked contact in GHL.
Actions: create or update a task under the linked contact using POST /contacts/:contactId/tasks and update with PUT as needed.
POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId
Key fields: taskId, title, dueDate, status.
Trigger: a note is added or updated in SimplyBook-me.
Actions: post a new note to /contacts/:contactId/notes and attach to the correct contact.
POST /contacts/:contactId/notes
Key fields: noteId, content, author.
Automate cross‑app data flow between SimplyBook-me and GHL without writing code.
Rapid setup with drag‑and‑drop builders, and quick testing in sandbox environments.
Consistent data across systems with clear audit trails and error handling.
A quick guide to the core elements and processes for connecting GHL’s Contacts API with SimplyBook-me, including endpoints, authentication, mappings, and workflows.
GHL API: The RESTful interface to access GHL resources like contacts, tasks, notes, and appointments.
Endpoint: A specific URL path used to perform a particular operation in the API, such as GET /contacts/:contactId.
Authentication: The method used to verify your app can securely access the API (API keys, OAuth).
Trigger: An event that starts a workflow in your integration, such as a new booking or a change in status.
Keep contact data in sync both ways. Validate emails and names during sync to maintain clean CRM records.
Auto-create or update tasks in GHL based on booking stages in SimplyBook-me, ensuring teams stay aligned.
Attach booking notes to the contact timeline in GHL for richer context during outreach and follow‑ups.
Create the integration in the GHL developer console and connect SimplyBook-me as a trusted app. Securely store API keys or set up OAuth.
Select the needed endpoints (contacts, tasks, notes). Map fields between SimplyBook-me and GHL so data aligns correctly.
Run tests in a sandbox, set up error handling, and move to production once you’re satisfied with reliability.
The GHL Contacts API provides programmatic access to contact data, tasks, notes, and appointments. It enables your apps to read and manage CRM data to automate workflows. You can retrieve records, create new entries, and update existing items as part of an integrated workflow. This API is designed to be used with OAuth or API keys for secure access. Use cases include syncing bookings, enriching contact records, and driving task automation from SimplyBook-me data.
Authentication is done via API keys or OAuth 2.0 flows. Create a private API key in your GHL account or set up OAuth credentials for your app. Always store credentials securely and request only the permissions you need (principle of least privilege). In Zapier, connect the GHL integration using the chosen auth method and test the connection before enabling live sync.
Key endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks for related tasks, POST /contacts/ to create a contact, and POST /contacts/:contactId/tasks to add tasks. Other endpoints cover notes, appointments, and bulk retrieval with GET /contacts/. Refer to the endpoint list in the integration guide to learn which operations fit your workflow.
Yes. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. Upserting (create or update) contacts helps keep records synchronized when a booking or contact record changes. Be mindful of required fields like name and email and map them consistently between SimplyBook-me and GHL.
Field mapping is done in the integration setup. Map core fields such as name, email, phone, and notes to their GHL equivalents. For tasks and notes, map task title, due date, and note content to the corresponding GHL fields. Test mappings in a sandbox to ensure data flows correctly and update mappings as your data model evolves.
You can often set up the integration without custom coding by using a no-code/low-code tool like Zapier. For advanced scenarios, you may add small scripts or use webhooks to handle complex field mappings or conditional logic. Always start in a sandbox to validate behavior before going live.
