How to connect GHL Contacts API with onOffice enterprise

This guide explains how to link GHL’s Contacts API with onOffice enterprise (APPNAME) to fetch, create, and manage contact data. You’ll learn authentication basics, endpoints used most often, and sample workflows that keep your CRM in sync.

Authentication for GHL Contacts API

Access to the Contacts API is secured. Use your GHL API credentials within the defined scope (contacts.readonly) to call endpoints and ensure data transfers occur over secure connections.

Authentication for onOffice enterprise

onOffice enterprise authenticates requests from the GHL app connector via OAuth2 or API tokens. Ensure tokens are stored securely and refreshed as needed.

Endpoints in this integration

Key endpoints you may use include: GET /contacts/:contactId to fetch a single contact, GET /contacts/:contactId/tasks to fetch tasks for a contact, GET /contacts/:contactId/tasks/:taskId for a specific task, GET /contacts/:contactId/notes and GET /contacts/:contactId/notes/:id for notes, GET /contacts/:contactId/appointments for appointment data, GET /contacts/ to list contacts, GET /contacts/business/:businessId for business-level queries, and the write/update/delete endpoints: 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, and POST /contacts/:contactId/tags.

3 simple steps to connect GHL and APPNAME

Step 1: Prepare credentials

Gather your GHL API credentials and onOffice enterprise tokens; store securely and test access with a simple read request.

Step 2: Authorize the app

Connect APPNAME in GHL using OAuth2 or API tokens; ensure the required scope is set (contacts.readonly).

Step 3: Build your first workflow

Create a Zap or workflow that calls GET /contacts/:contactId and maps fields to onOffice, then test end-to-end.

Frequently asked questions

What data can I access with the Contacts API in this integration?

The Contacts API provides read access to contact records, tasks, notes, and related data. You can fetch single contacts by ID, pull lists of contacts, and retrieve associated items such as tasks and notes. This enables you to build workflows that surface up-to-date information in onOffice. Additionally, the API supports creating and updating related items to keep data in sync across systems.

No coding is required to use these endpoints within a compatible automation platform like Zapier. You can configure triggers, actions, and mappings using visual builders. For complex transformations, consider light scripting within your automation environment, but it is not mandatory.

Authentication typically uses tokens issued by GHL and onOffice, or OAuth flows if supported. Keep credentials secure and refresh tokens as needed. Your workflow should include steps to securely store and rotate tokens.

A simple starting point is GET /contacts/:contactId to verify connectivity, then extend to fetch tasks (GET /contacts/:contactId/tasks) and create tasks (POST /contacts/:contactId/tasks) as your use case evolves.

Yes. Use the PUT /contacts/:contactId or POST /contacts/ endpoints to update or create contact records in onOffice. Ensure you map fields correctly and handle conflicts gracefully.

If you hit rate limits, implement exponential backoff and retry logic in your automation. Handle API errors by inspecting status codes and messages returned by the endpoint. Logging helps diagnose persistent issues.

Endpoint details, parameter options, and payload structures are documented in the integration’s endpoint list above. You can also consult APPNAME’s developer docs for fields and mappings.
