Use OAuth 2.0 with your GHL account to authorize APPNAME to access Contacts data. Store tokens securely and refresh them as needed.
Obtain API credentials for APPNAME (client ID and client secret) and configure them in your integration settings to authorize requests to the GHL Contacts API.

Automates data sync between APPNAME and GHL, reducing manual updates.
Keeps contact info consistent in real time for better segmentation and reporting.
Enables event-driven workflows without writing code, accelerating time to value.
This glossary explains core elements and processes used in the GHL Contacts API integration: contacts, tasks, notes, appointments, and tags.
A person record in GHL containing identifiers such as name, email, phone, and related data.
A free-form entry attached to a contact for context or history.
An action item assigned to a contact with a due date and completion status.
A label used to categorize or segment contacts for targeting or grouping.
Automatically pull and sync enriched contact data from APPNAME into GHL to keep records current.
Create and update tasks in GHL based on APPNAME events to ensure timely follow-ups.
Apply tags from APPNAME to contacts in GHL to power targeted campaigns and automation.
Register APPNAME in GHL to obtain client credentials (client_id and client_secret), then store them securely in APPNAME.
Link APPNAME fields to Contacts API fields (name, email, tags) and configure endpoint permissions.
Run end-to-end tests, verify data sync accuracy, and enable live mode in production.
The GHL Contacts API is a dedicated interface for reading and writing contact records, including related entities like tasks, notes, and tags. It enables programmatic access to manage customer data from your app. When used with APPNAME, you can keep records in sync and drive automation across platforms. The API is designed to be secure, scalable, and easy to integrate with common authentication flows.
Authentication for the integration uses OAuth 2.0 to grant APPNAME access to GHL Contacts data without sharing user credentials. Start by obtaining client credentials from GHL, then exchange authorization codes for access tokens and refresh tokens. Store tokens securely and refresh them before expiry to maintain uninterrupted access.
Key endpoints include GET /contacts/:contactId to fetch a contact, POST /contacts/ to create, PUT /contacts/:contactId to update, and DELETE /contacts/:contactId to remove. You can also manage related data with endpoints for tasks, notes, appointments, and tags, such as POST /contacts/:contactId/tasks and POST /contacts/:contactId/tags.
To test, use a sandbox or staging environment to simulate real-world flows. Create a test contact, add a task and a note, apply a tag, and verify data sync from APPNAME to GHL. Check logs for any errors, validate field mappings, and confirm that triggers fire as expected.
Yes. You can synchronize tasks, notes, and tags alongside contacts. Use the corresponding endpoints (tasks: POST/PUT/DELETE; notes: GET/POST; tags: POST) to ensure all related data remains consistent across systems.
Field mapping is done in the integration setup. Map APPNAME fields to GHL Contacts fields (e.g., name to name, email to email, tags to tags). Validate required fields, handle optional fields gracefully, and implement fallback values where needed.
Rate limits vary by endpoint and plan. Monitor API usage in the GHL developer console, implement exponential backoff for retries, and batch requests when possible to stay within limits while maintaining data freshness.
Due to high volume, we will be upgrading our server soon!
