Use OAuth 2.0 credentials issued in your GHL developer console to authorize the integration and grant the scope contacts.readonly.
In Zapier, configure a secure connection using OAuth tokens or API keys and test the connection to ensure secure data transfer.
Endpoints cover contacts and related data. For example GET /contacts/:contactId retrieves a contact, GET /contacts/:contactId/tasks fetches tasks, GET /contacts/:contactId/notes retrieves notes, and GET /contacts/:contactId/appointments returns appointments. Other endpoints enable creating and updating contacts, tasks, and tagging as needed.
Trigger when a contact is added or updated in Greenhouse to keep systems in sync.
Actions include creating, updating and deleting contacts, attaching notes, and syncing tags.
Key endpoints for this flow include GET /contacts/:contactId and PUT /contacts/:contactId.
Fields to map include contactId, name, email, phone, businessId, and tags.
Trigger on new or updated tasks and notes for a contact.
Actions include creating tasks, updating task status, and adding notes.
Endpoints include POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId and GET endpoints for tasks and notes.
Key fields: taskId, id, noteId, contactId, subject, content.
Trigger when an appointment is scheduled or tags are updated.
Actions: schedule appointments, assign tags, update contact tags.
Endpoints include GET /contacts/:contactId/appointments and POST /contacts/:contactId/tags and PUT /contacts/:contactId/tags/:tagId.
Key fields: appointmentId, contactId, businessId, tag.
Automate CRM workflows without writing code.

This glossary explains API, endpoints, triggers, actions, scopes, and OAuth in the context of connecting the Contacts API with the Zapier App Connector.
An interface that lets two applications talk to each other and exchange data.
A specific URL for a defined operation in an API.
The standard protocol for secure authorization used to obtain access tokens.
A lightweight callback that pushes data to your app in real time.
Automatically push new or updated contacts from Greenhouse to your marketing tools for instant campaigns.
Create or update tasks in your project manager when contact details change.
Tag contacts automatically based on activity to tailor outreach.
In GHL, create an OAuth client and authorize your Zapier app to access Contacts data.
Select triggers like new or updated contact and map actions to endpoints accordingly.
Run tests for your flows and deploy the integration once confirmed.
First, the Contacts API uses the scope contacts.readonly to retrieve data. If you need write access, configure the OAuth client with contacts.write and request the appropriate permissions. Be sure the OAuth client is granted the correct scopes before testing. Be sure to test read operations before enabling write actions in a live environment.
No code is required for most automations in Zapier App Connector. You can set up triggers and actions using the visual builder. For more advanced flows, you may leverage custom fields and optional webhooks. If your use case grows, you can extend with conditional logic and multi-step workflows.
Yes. You can fetch tasks and notes for a contact using endpoints like GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes. These responses can drive triggers and actions in Zapier. Combine these with additional endpoints to build a complete activity trail for each contact.
Authenticate using OAuth 2.0. Your Zapier connection will store tokens securely and refresh them as needed. Ensure the redirect URI is registered correctly in the GHL developer console. Test the connection in Zapier to confirm live access to Contacts data.
Rate limits vary by endpoint and plan. Plan for retries and exponential backoff in high-volume scenarios. If you anticipate higher throughput, contact support to explore options or adjust quotas. Monitor responses and implement proper error handling in your workflows.
Yes, tagging is supported. Use POST /contacts/:contactId/tags to add tags and manage tag assignments as part of your automation flows. You can conditionally apply tags based on contact activity or attributes to segment audiences effectively.
API endpoints are documented in the GHL developer portal and can be tested in a dedicated API playground. You can copy sample requests, view responses, and try different parameters. Use the endpoint list to plan data transfers and verify permissions before building your Zapier automations.
Due to high volume, we will be upgrading our server soon!
