Use token-based authentication with a Bearer token and the required scope: contacts.readonly. Store credentials securely and rotate tokens regularly.
Configure OAuth 2.0 in Zapier to obtain access and refresh tokens for the GHL Contacts API, ensuring the contacts.readonly scope is granted where needed.

Trigger on updates to a contact or when related data (tasks, notes) changes, using GET endpoints to pull fresh data.
Actions include fetching contact details, tasks, and notes and mapping fields to Zapier actions or filters.
GET /contacts/:contactId
contactId, name, email, phone, status
Trigger on new or updated tasks for a contact via GET /contacts/:contactId/tasks
Map task fields to create or update tasks in your automation workflows.
GET /contacts/:contactId/tasks
taskId, title, dueDate, status
Trigger on new notes or appointments for a contact using GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments
Map notes and appointments to your workflows and optionally create follow-up tasks via POST /contacts/:contactId/tasks
GET /contacts/:contactId/notes
notesId, content, appointmentDate
Build powerful field service automations without writing a line of code.
Accelerate data workflows with ready-to-use endpoints and mapping templates.
Scale operations by connecting GPS Insight data to your favorite apps.
A quick glossary of terms and the processes used to connect GHL Contacts API with the Zapier App Connector for Field Service Management.
A specific URL path through which you access a resource or action in an API. Each endpoint corresponds to an operation like reading, creating, or updating data.
A standard protocol for authorization that issues access tokens to clients with defined scopes.
A token used in the Authorization header to prove identity and grant access to API resources.
A defined set of permissions that determine what actions a client can perform via an API.
When a new contact is created in GPS Insight, automatically generate a follow-up task in Zapier to assign work and track progress.
Push GPS Insight appointments to Google Calendar or Outlook via Zapier to keep teams aligned.
Create notes in the system and trigger follow-up tasks when notes are added, improving service history.
In Zapier, authorize access to the GHL Contacts API with the required scope (contacts.readonly).
Select endpoints like GET /contacts/:contactId and map fields to your Zapier actions.
Run test tasks to verify data flow and set up monitoring alerts.
The Contacts API provides programmatic access to contact records, tasks, notes, and appointments within GPS Insight Field Service data. It enables you to read, create, update, and delete records to automate service workflows. By connecting it to the Zapier App Connector, you can drive no-code automations across your favorite apps. This makes it easy to keep field teams aligned and data synchronized without manual imports.
Authentication uses Bearer tokens with defined scopes. When you connect the GHL Contacts API to Zapier, you will configure OAuth 2.0 or token-based authentication depending on your setup, ensuring the required scope (contacts.readonly) is granted. Securely store tokens and refresh as needed to maintain uninterrupted access.
Key read endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments. These allow you to pull current data for a contact, its tasks, notes, and scheduled appointments for workflows and reporting.
Yes. Endpoints like POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, and DELETE /contacts/:contactId/tasks/:taskId enable full task lifecycle management from your automations.
Rate limits depend on your API plan and endpoint usage. To avoid throttling, design efficient workflows, batch requests where possible, and implement retry logic with exponential backoff. If you anticipate high volume, consider tiered plans or contacting support for guidance.
In Zapier, use the built-in field mapping to align API response fields (e.g., contactId, name, taskId, dueDate) with Zapier action inputs. This ensures data flows correctly between GPS Insight and connected apps. Test mappings thoroughly in a sandbox before going live.
If you require additional endpoints or capabilities beyond the provided list, you can request API access extensions or explore custom integration options. In many cases, combining existing endpoints with Zapier workflows covers most field service use cases.
Due to high volume, we will be upgrading our server soon!
