Access to the Contacts API requires proper authentication. Use your GHL API key with the defined scope (contacts.readonly) and rotate credentials regularly to maintain security.
In Zapier, connect the GHL integration using OAuth 2.0 where available or an API key, then store tokens securely and refresh as needed.
– 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 (permission) – 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 new contact is created or updated in GHL; fetch full details via GET /contacts/:contactId to populate your Zap.
Actions can include creating tasks, notes, or updating fields using the corresponding POST/PUT endpoints.
GET /contacts/:contactId
Key fields: id, name, email, phone, status, custom fields
Trigger on updates from Zapier to GHL to keep fields in sync; use PUT /contacts/:contactId.
Actions: update name, email, phone, tags; ensure last_modified tracking.
PUT /contacts/:contactId
Key fields: id, name, email, phone, tags, custom_fields
When notes or tasks are created/updated in GHL, push data to Zapier to update other systems, or vice versa.
Actions: POST /contacts/:contactId/notes, POST /contacts/:contactId/tasks, or PUT to complete tasks.
POST /contacts/:contactId/notes; POST /contacts/:contactId/tasks
Fields: content, due_date, status, priority
No-code automation to connect CRM data with spreadsheets, email, and support tools.
Frictionless data flow and task automation across platforms.
Scalable workflows with REST endpoints for robust integrations.
This section explains API terms, endpoints, authentication, triggers, actions, and data fields used in these integrations.
A set of rules and tools that lets two software programs communicate with each other, enabling data transfer and actions.
A specific URL path in the GHL Contacts API used to perform a particular operation.
A method to push real-time data between apps; not required for REST-based triggers but common in integrations.
Verification of identity and permission to access API resources.
When a new contact is added in GHL, automatically create a welcome task and a note in the CRM.
Update contact status and trigger follow-up messages via Zapier actions.
Link support tickets to contact notes and tasks for a complete history.
Add Contacts API as the trigger or action app and authenticate using the GHL API key or OAuth.
Run test searches to fetch a sample contact and verify fields map correctly.
Create a Zap that uses endpoints like POST /contacts/ and PUT /contacts/:contactId to automate tasks and notes.
No coding is required for basic automation setup using the Zapier App Connector. The UI lets you define triggers (events in GHL) and actions (updates in GHL or other apps) without writing code. For more advanced logic, you can add filters, paths, or code steps within Zapier. This makes it easy to map data between GHL and your stack with minimal setup.
Essential endpoints for typical workflows include GET /contacts/:contactId to read data, POST /contacts/ to create a new contact, PUT /contacts/:contactId to update, and POST /contacts/:contactId/tasks or POST /contacts/:contactId/notes to attach activities. Tags can be managed with POST /contacts/:contactId/tags. These endpoints cover creating, updating, and enriching contact records within automated flows.
Authentication uses a GHL API key with a defined scope (such as contacts.readonly or contacts.write). Keep keys secure and rotate regularly. In Zapier, use OAuth where supported or securely store API keys and refresh tokens. Ensure the connected app has proper permissions before triggering any actions.
Yes. You can configure triggers from GHL to Zapier to start workflows and set actions in Zapier to update GHL (or other apps). Webhooks or polling can be used, depending on the endpoint and your setup. Always test two-way data flow to confirm fields map correctly and avoid data drift.
When creating a contact via POST /contacts/, required fields typically include at least name and email. Other fields are optional but recommended for richer data. Ensure the request uses the proper scope (contacts.write) and that mandatory fields align with your GHL configuration. Validate responses to confirm the new contact ID was created.
Test your integration using Zapier’s test requests and a sample contact. Check the task history and API responses to verify fields map correctly. Use test data that covers all required fields and edge cases, then gradually move to live data after successful tests.
Error logs can be found in Zapier task history and in the API response bodies returned by GHL. Enable debugging if available, review rate limit headers, and consult the API docs for recommended retry behavior. Troubleshooting tips include verifying authentication, scope, and endpoint correctness.
Due to high volume, we will be upgrading our server soon!
