Access to the Contacts API in this integration uses a scoped token. The required scope is contacts.readonly, enabling read access to contacts, tasks, notes, and related resources.
In Zapier, authorize the connection by selecting the Contacts API (GHL) as the app and providing the client credentials. Save credentials securely and reuse them for all automations.
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; Permissions: 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
When a new contact is created in CallTrackingMetrics, push the contact data to Contacts API to create or update a record.
Actions include: create or update contact, attach tasks, and add notes from CallTrackingMetrics.
Example methods: POST /contacts/ to create a contact, PUT /contacts/:contactId to update fields.
Key fields: contactId, firstName, lastName, email, phone, status, tags
Pull a complete activity profile when you need to review a contact’s history.
Actions: list tasks, notes, and appointments; fetch related business data.
Example: GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes; GET /contacts/:contactId/appointments
Key fields: contactId, taskId, noteId, appointmentId
Trigger on contact updates to drive task completion and tag application.
Actions: update tasks, complete items, and add or remove tags.
Examples: POST /contacts/:contactId/tasks; POST /contacts/:contactId/tags
Key fields: contactId, taskId, tagId
Automate routine data sync between CallTrackingMetrics and Contacts API without writing code.
Build powerful workflows in Zapier App Connector to trigger actions from events in either system.
Scale outreach and keep customer data synchronized across tools with minimal setup.
This glossary defines common terms used in this guide: API endpoint, authentication, webhooks, contact, tag, and task. Understanding these terms helps you design robust automations.
A specific URL and HTTP method used to access a resource in an API.
The process used to verify identity and authorize access (for example OAuth 2.0 or API keys).
A URL that receives real-time event notifications from an app when something changes.
A record in the Contacts API representing a person or company.
Set up a two-way sync so updates in either system reflect in the other, reducing manual data entry.
Whenever a contact is updated, automatically create a follow-up task or note in the counterpart system to maintain momentum.
Sync important notes and tags to keep context consistent across CallTrackingMetrics and Contacts API.
Obtain credentials for the Contacts API in GHL and connect them in Zapier App Connector.
Choose endpoints you need and map fields between systems.
Run tests, verify data integrity, and enable automation.
No coding is required to connect GHL Contacts API with the Zapier App Connector. The integration uses pre-built triggers and actions to move data between CallTrackingMetrics and Contacts API. In cases where you need custom logic, you can add filters, paths, and multi-step zaps to tailor your workflow without writing code.
Authentication is handled through secure OAuth 2.0 (or API keys where supported) within the Zapier app. The app connection stores credentials safely. You can refresh tokens and manage permissions from the connections page.
Many endpoints are available depending on your needs. Common automations use GET /contacts/:contactId to fetch data, POST /contacts/ to create, PUT /contacts/:contactId to update, and POST /contacts/:contactId/tasks to create tasks. Combine endpoints with triggers and actions to build end-to-end workflows.
Yes. The integration supports updating and deleting contacts via the Contacts API endpoints when you have the appropriate permissions. Be mindful of rate limits and ensure you handle conflicts gracefully in your Zap.
If an error occurs, Zapier will retry the step according to its built-in retry logic. You can also add error paths to handle failures. Log and notify your team on persistent errors, and consider implementing idempotent actions to avoid duplicates.
There is no fixed limit on how often you can sync via the Zapier app, but you should design efficient zaps to avoid unnecessary calls and respect your plan’s quotas. For heavy data loads, batch or scheduled triggers can help manage frequency responsibly.
API rate limits and quotas are documented in your GHL developer portal for the Contacts API. Your app’s quota depends on your plan. If you approach limits, implement exponential backoff and fan-out strategies in your automation.
Due to high volume, we will be upgrading our server soon!
