Authenticate with OAuth 2.0 tokens. Include the access token in the Authorization header and use the scope contacts.readonly for read operations.
Register your app with the API provider, obtain client credentials, and exchange them for access tokens. Store tokens securely and refresh them before expiry.
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
Triggered when a user grants access or initiates a sync from your app.
Actions include fetching contact data, creating new contacts, updating fields, and reading related tasks or notes.
Use REST calls with GET, POST, PUT and DELETE against the documented endpoints.
Key identifiers include contactId, taskId, noteId, businessId.
Triggered by live updates from Zoho FSM to trigger app workflows via webhooks.
Actions include reacting to webhooks to create or update records in your app.
Set up webhook endpoints and subscribe to events for contacts and tasks.
Fields like contactId, eventType, timestamp are used to map data.
Scheduled sync runs at configured intervals to pull or push data.
Batch-style endpoints and payloads for multiple contacts in a single call.
Fields include contactId, batchSize, timestamp.
Quick setup without coding to sync data between Zoho FSM and your app.
Automated, ongoing data sync reduces manual entry.
Scales with your business needs and supports automation.
This glossary defines API endpoints, authentication flows, webhooks, rate limits, and data objects used in this integration.
A specific URL path that performs a function via the API.
Authorization framework that grants access without sharing user credentials.
Event driven notification sent to a configured URL when data changes.
Limits on API calls per minute or hour to protect services.
Automatically populate contact fields from Zoho FSM updates to save time.
Route tasks to teams based on contact properties to speed up work.
Trigger workflows immediately when Zoho FSM changes occur.
Obtain OAuth tokens and authorize app access.
Set up endpoints and payload mappings.
Test thoroughly and deploy.
The Contacts API in GHL exposes endpoints to read and manage contact data such as profile, tasks, notes. It helps you build apps that stay in sync with CRM data. Use the authentication flow to securely grant access to your app.
To authenticate, obtain an OAuth 2.0 token by registering your app and completing the authorization code flow. Then exchange the code for access and refresh tokens. Include the access token in the Authorization header for each request. Tokens expire, so refresh as needed.
Endpoints for managing contacts include GET /contacts/:contactId, POST /contacts, PUT /contacts/:contactId, DELETE /contacts/:contactId, and related endpoints for tasks, notes, and tags. You can also fetch lists with GET /contacts and retrieve related data via nested endpoints like /contacts/:contactId/tasks and /contacts/:contactId/notes.
Yes, you can update data in near real time using PUT endpoints and by subscribing to webhooks. Webhooks deliver updates as soon as changes occur, enabling immediate sync with your app.
When errors occur, check the HTTP status codes and error messages. Implement retries with exponential backoff and respect 429 Too Many Requests guidance. Log failures and adjust payloads or rate usage as needed.
Yes, webhooks exist for real time updates. Configure your listener URL, verify delivery, and handle retries to ensure you receive all events. You can also verify data by querying the available endpoints after events fire.
Due to high volume, we will be upgrading our server soon!
