GHL requires a client credential flow and the correct scope. For reading contact data, use the scope: contacts.readonly. Protect your API keys and rotate tokens periodically for security.
To authorize APPNAME, create an OAuth client in APPNAME, request access to the GHL Contacts API with the required scope, and securely store the access and refresh tokens for ongoing use.
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: When a contact is created or updated in GHL, APPNAME fetches the latest data to stay in sync.
Actions: Retrieve contact details, including core fields, and sync related tasks, notes, and tags back to APPNAME.
GET /contacts/:contactId
Key fields: contactId, email, name, lastUpdated
Trigger: When a cohort of contacts is updated or tagged for tasks.
Actions: Pull /contacts/:contactId/tasks and push any updates to APPNAME; mirror notes when present.
GET /contacts/:contactId/tasks
Key fields: contactId, taskId, status
Trigger: When notes are added or updated on a contact in GHL.
Actions: Sync notes to APPNAME with noteId, content, and timestamp; attach to the contact record.
GET /contacts/:contactId/notes
Key fields: contactId, noteId, content
Faster time-to-value with no-code data flows: drag-and-drop automation enables rapid data syncing between GHL and APPNAME.
Automatic data sync reduces manual entry and human error, keeping records aligned across systems.
Unified contact views across platforms empower smarter segmentation and proactive outreach.
A quick glossary of terms used in this guide: GHL API, Contacts API, endpoint, trigger, action, OAuth, and scope.
The RESTful interface provided by GHL to read and write data for contacts, tasks, notes, and more.
A specific URL path used to perform an operation, such as GET /contacts/:contactId.
An event that starts a workflow (for example, a contact is created or a task is updated).
An operation performed in response to a Trigger (for example, create a task or update a note).
Route new contacts to the right segment in APPNAME based on source, tags, and lifecycle stage using real-time data from the GHL API.
Batch related tasks from GHL into single APPNAME workflows to streamline team workloads and updates.
Maintain a complete activity history in APPNAME by syncing notes, tasks, and changes with timestamps from GHL.
Gather your GHL API credentials, confirm the scope (contacts.readonly), and set up your APPNAME OAuth client for authorization.
Register APPNAME as an app in GHL, request the appropriate scope, and securely store access and refresh tokens after consent.
Run test calls like GET /contacts to verify responses and validate data syncing between GHL and APPNAME.
The GHL Contacts API is a RESTful interface that lets you read and manage contact data, tasks, notes, and more. It enables programmatic access to the same data you would manage in your GHL account, so you can build integrations with APPNAME and other tools. Common operations include retrieving a single contact with GET /contacts/:contactId and listing contacts with GET /contacts/.
Available endpoints cover reading, creating, updating, and deleting contacts, tasks, and notes, as well as managing attachments and tags. You can compose workflows by combining endpoints such as GET /contacts/:contactId, POST /contacts/, and PUT /contacts/:contactId/tasks/:taskId. This enables end-to-end data sync between GHL and APPNAME.
Authenticate APPNAME via OAuth 2.0, request the needed scope (typically ‘contacts.readonly’ for read access), and securely store tokens. Use refresh tokens to maintain access without requiring user re-consent. Rotate credentials periodically for security.
You can implement many flows with no-code tools by chaining API calls in workflows. Some scenarios may benefit from light scripting to handle token refreshes or complex field mappings. Zapier, Make, or custom connectors can all be leveraged depending on your needs.
For read-only access, the required scope is ‘contacts.readonly’. If you need to create, update, or delete data, additional scopes such as ‘contacts.write’ may be required. Always request the minimum scope necessary for your integration.
Yes. Zapier can call GHL endpoints via Webhooks or HTTP actions to sync data with APPNAME. You can set triggers such as ‘New Contact’ and actions like ‘Create/Update Contact’ to automate workflows with minimal code.
Data synced from GHL appears in APPNAME’s CRM views and related records. You can review changes in APPNAME’s activity logs and use the updated fields for segmentation and automation.
Due to high volume, we will be upgrading our server soon!
