Authenticate requests with your GHL credentials (API keys or OAuth) and apply the scope contacts.readonly to protect data.
Register APPNAME in the GHL developer portal, generate credentials, and configure scopes to control access to contacts.
Endpoints include: 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 APPNAME creates or updates a contact to keep GHL in sync.
Actions: map and push name, email, phone, and custom fields to POST /contacts/ and PUT /contacts/:contactId.
Method path examples: POST /contacts/ to create a contact; PUT /contacts/:contactId to update.
Key fields: name, email, phone, address, customFields
Trigger: when APPNAME creates or updates a task, sync to GHL.
Actions: create and update tasks using POST /contacts/:contactId/tasks; update status with PUT /contacts/:contactId/tasks/:taskId; mark completed via PUT /contacts/:contactId/tasks/:taskId/completed.
Paths: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId.
Key fields: taskId, contactId, status, dueDate, description
Trigger: when APPNAME updates notes or tags to reflect in GHL.
Actions: create notes (POST /contacts/:contactId/notes); create tags (POST /contacts/:contactId/tags); fetch related notes and tags as needed.
Paths: POST /contacts/:contactId/notes; POST /contacts/:contactId/tags.
Key fields: contactId, noteId, tagName
Build complex automations without writing code using visual workflows.
Rapid data synchronization across systems with drag-and-drop integrations.
Unified data model for contacts, tasks, notes, and tags across APPNAME and GHL.
This section describes the core elements: endpoints, authentication, triggers, actions, and data mappings used to connect APPNAME with GHL.
A defined interface that lets software communicate with a service.
A specific URL and method that performs a single operation in the API.
An event that starts an automation or workflow.
An operation executed in response to a trigger.
Automatically enrich GHL contacts with APPNAME data fields via endpoints 1 and 2.
Create automated task lifecycles in GHL from APPNAME events.
Sync notes and tags to preserve context across systems.
Obtain credentials for APPNAME and GHL, configure scopes, and test the connection.
Map fields between APPNAME and GHL contacts, tasks, notes, and tags.
Run tests, monitor logs, and flip the switch to go live.
You can connect APPNAME to GHL with no code using integration tools like Zapier or Make, which can call endpoints such as POST /contacts/ to create a contact and PUT /contacts/:contactId to update it. These workflows are designed to be visual and beginner-friendly. If you prefer to build directly, you can call the HTTP endpoints from any programming language using standard REST calls and handle authentication in code.
Authentication is required to protect data. Use GHL API keys or OAuth credentials to authorize requests, and apply the appropriate scopes (for example, contacts.readonly) to limit access. APPNAME should authenticate using its own credentials and request access with the necessary scopes.
For managing contacts you will primarily use GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId. You can also access related resources like tasks and notes via their respective endpoints. This provides a complete set of operations to manage contact data.
Yes. You can automate task creation, status updates, and completion. Use POST /contacts/:contactId/tasks to create tasks, PUT /contacts/:contactId/tasks/:taskId to update, and PUT /contacts/:contactId/tasks/:taskId/completed to mark completion.
Data mapping lets you align fields between APPNAME and GHL (for example, name, email, phone, and custom fields). Use the API to read data from APPNAME and write to GHL, or pull GHL data into APPNAME as needed. Keep field mappings consistent to ensure data integrity.
Webhooks are supported in some configurations to notify APPNAME of changes in GHL or vice versa. Set up webhooks to trigger automations when a contact, task, or note is updated.
API rate limits depend on your GHL plan. Plan for retries and exponential backoff, and batch requests where possible to stay within quotas while maintaining data freshness.
Due to high volume, we will be upgrading our server soon!
