The Contacts API uses API tokens or OAuth-based authentication to securely access your data. Keep your credentials safe and rotate keys regularly.
SITE123 uses standard OAuth2-compatible flows to authorize API calls. When you connect, you’ll grant access with scoped permissions to read or modify contact data.
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
Trigger: When viewing or syncing a contact in SITE123, pull the contact’s core data with GET /contacts/:contactId.
Actions: fetch contact, retrieve associated tasks and notes, then update SITE123 CRM fields accordingly.
GET /contacts/:contactId
Key fields: contactId, name, email, phone, lastActivity
Trigger: When a new contact is created in SITE123, push data to GET /contacts/ or POST /contacts/.
Actions: create or update contact in the Contacts API, assign tags, and schedule tasks.
POST /contacts/
Key fields: name, email, phone, tags
Trigger: When a contact’s tasks change in SITE123, sync updates to /contacts/:contactId/tasks and related notes.
Actions: update tasks via PUT /contacts/:contactId/tasks/:taskId and ensure completed status matches SITE123.
PUT /contacts/:contactId/tasks/:taskId
Key fields: taskId, status, dueDate, assignee

Aggregate contact data from SITE123 and the Contacts API to present a single profile.
Generate API keys or OAuth credentials in the GHL dashboard and note the scopes required for read/write access.
In SITE123, set up the API calls to match the available endpoints and map fields to SITE123 contact fields.
Test requests in a sandbox, verify responses, then deploy the integration to production.
The integration exposes endpoints such as GET /contacts/:contactId and related resources like tasks, notes, and appointments. These endpoints support fetching data for a single contact, plus associated items for a complete view. You can select only the endpoints you need based on your SITE123 workflows. Ensure you use the correct contactId to pull the targeted record. Note: Some endpoints may require different permissions; refer to the scope listed in your credentials.
To fetch a contact and its tasks, call GET /contacts/:contactId to retrieve the core contact data, then GET /contacts/:contactId/tasks to pull the related tasks. You can combine these responses in SITE123 to present a unified view. Use stable identifiers and handle pagination if the API returns large task lists.
Yes. You can create contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. Make sure the payload includes required fields like name and email, and that you assign any relevant tags or business associations as needed.
Permissions are controlled by API credentials and scopes. Use scopes such as contacts.readonly for read access or a broader scope for write operations. Always follow the principle of least privilege and rotate credentials regularly.
You can read core contact fields (name, email, phone, etc.), notes, tasks, and appointments. Write capabilities include creating and updating contacts, tasks, and tags. Some endpoints are read-only, depending on the credential scope.
Test the integration with a sandbox or test environment. Validate request formats, response structures, and error handling. Use sample payloads aligned with the endpoint you’re hitting and verify that SITE123 maps fields correctly.
API credentials are issued from your GHL account or the connected app. Look for API keys or OAuth client credentials in the developer or integration section of the dashboard, then authorize SITE123 to access with the needed scopes.
Due to high volume, we will be upgrading our server soon!
