Authenticate the GHL Contacts API access via the Zapier App Connector using standard OAuth 2.0 flows and API keys. Ensure your scope is set to read-only for safety unless write access is required.
Configure the Zapier App Connector to request the necessary permissions (including the contacts.readonly scope) and securely store tokens. Use OAuth where available and rotate credentials regularly.
Endpoints for the FreshBooks Contacts API: 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; 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. Permissions required include contacts.write when creating or updating data.
Trigger: fetch a contact by ID when requested in a workflow.
Actions: retrieve contact details, including name, email, phone, and status; optionally pull related notes or tasks.
GET /contacts/:contactId
contactId, name, email, phone, status
Trigger: when tasks are requested for a contact during a workflow.
Actions: return list of tasks with IDs, titles, statuses, and due dates.
GET /contacts/:contactId/tasks
contactId, taskId, title, status, dueDate
Trigger: retrieve a specific task by ID for a contact.
Actions: fetch task details, status, and related notes or timestamps.
GET /contacts/:contactId/tasks/:taskId
contactId, taskId, title, status, dueDate
Build powerful automations without writing code to sync FreshBooks data with GHL via the Zapier App Connector.
Speed up workflows with ready-to-use endpoints and triggers designed for common business processes.
Easily map fields and keep records synchronized across FreshBooks and GHL.
This glossary explains the essential terms you’ll encounter when connecting the GHL Contacts API with the Zapier App Connector.
A specific URL in an API that performs a function or returns data.
A callback URL that lets an app push data to you in real time when events occur.
The process of proving identity and permissions before granting API access (e.g., OAuth, API keys).
The maximum number of API requests allowed in a time window to protect the service.
Create a workflow that adds a FreshBooks client as a new contact in GHL, then assigns onboarding tasks and creates follow-up notes automatically.
When a contact field changes in GHL, automatically generate or adjust related tasks in FreshBooks to reflect new work items.
Use notes in GHL to apply tags in FreshBooks, enabling targeted campaigns and smoother segmentation.
Authorize access to the GHL Contacts API and the Zapier App Connector for secure data exchange.
Choose the endpoints you need and map triggers and actions in Zapier to your workflow goals.
Run tests, verify data mappings, and deploy the automation to production.
You do not need to write code to connect GHL with Zapier App Connector. The platform provides a visual builder to configure triggers, actions, and field mappings. If you are comfortable with basic data mapping, you can set up most common automations without coding. For advanced workflows, you can still leverage custom fields and conditional logic in Zapier. If you do encounter limitations, consult the integration documentation or contact support for guidance on alternative flows that achieve your goals.
For a basic sync, start with getting a single contact (GET /contacts/:contactId) and pulling its associated tasks (GET /contacts/:contactId/tasks). This establishes core data flow: contact details and task context. You can expand to notes, appointments, and tags as needed. As you scale, add additional endpoints in a staged approach to keep maintenance simple and predictable.
Security is handled via standard OAuth 2.0 and API key mechanisms, with scoped permissions. Data is transmitted over TLS, and tokens can be rotated regularly. In Zapier, you control which data fields are exposed to workflows, helping minimize risk. Review each endpoint’s permissions and audit logs to maintain compliance.
Yes. The mapping interface in Zapier lets you align fields between GHL Contacts and FreshBooks data. You can map standard fields (name, email, phone) and custom fields. Complex mappings may require multi-step logic or additional actions to transform data before it’s written to the target system.
If an endpoint returns an error or you hit a rate limit, Zapier will surface the error with details. You can implement retry logic, backoff strategies, and error handlers within your workflow. Regularly monitor task history and logs to identify recurring issues and adjust mappings or endpoints accordingly.
Yes. You can trigger actions in FreshBooks from GHL events by wiring up appropriate triggers in Zapier (for example, when a contact is updated in GHL, create or modify a related task in FreshBooks). This enables cross-system workflows that stay in sync as events occur.
Zapier provides built-in task history and debugging tools. You can view trigger runs, action results, and data mappings. For deeper debugging, enable verbose logging and consult the endpoint responses to adjust field mappings or endpoints as needed.
Due to high volume, we will be upgrading our server soon!
