To call the GHL API from Zapier, secure requests with a valid API key or OAuth token. Use the Authorization header with a Bearer token and scope appropriate for the operation (e.g., contacts.readonly for reads).
In Zapier, set up a connection using OAuth 2.0 or an API key depending on your setup. Then link your GHL account and grant permissions for reading and writing contacts, tasks, notes, and appointments.
GET /contacts/:contactId — Retrieve a single contact GET /contacts/:contactId/tasks — List tasks for a contact GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task GET /contacts/:contactId/notes — List notes for a contact GET /contacts/:contactId/notes/:id — Retrieve a specific note GET /contacts/:contactId/appointments — List appointments for a contact GET /contacts/ — List all contacts GET /contacts/business/:businessId — Retrieve contacts for a business Endpoint9: contacts.write POST /contacts/ — Create a new contact PUT /contacts/:contactId — Update a contact DELETE /contacts/:contactId — Delete a contact POST /contacts/:contactId/tasks — Create a task for a contact PUT /contacts/:contactId/tasks/:taskId — Update a task PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task as completed DELETE /contacts/:contactId/tasks/:taskId — Delete a task POST /contacts/:contactId/tags — Add tags to a contact
Trigger on contact updates or new records by polling GHL or by using Zapier Webhooks to fetch data from endpoints like GET /contacts/:contactId and related resources.
Actions include creating, updating, or deleting contacts, tasks, notes, and tags using POST, PUT, DELETE endpoints as listed above.
Key methods: GET for reads; POST for creates; PUT for updates; DELETE for removals. Example paths are shown in the endpoint list.
Map core identifiers like contactId, taskId, noteId, and businessId to Zapier fields; ensure primary keys align between GHL and Zapier objects.
Use Zapier’s Webhooks trigger to receive data pushes from GHL or poll endpoints for changes in contacts, tasks, or notes.
Actions include updating GHL records, attaching notes, creating tasks, and tagging contacts via the appropriate PUT/POST endpoints.
Common methods include GET, POST, PUT, and DELETE across the listed endpoints to keep data in sync.
Key mappings should include contactId, taskId, noteId, and businessId; align Zapier fields to corresponding GHL fields for accurate data sync.
Schedule or event-based triggers can automate contact onboarding, task creation, and status updates without writing code.
Templates can automatically create contacts from forms, update tasks, and push notes to GHL as actions within Zapier workflows.
Use combinations of GET/POST/PUT/DELETE across the endpoints to implement end-to-end workflows.
Ensure IDs (contactId, taskId, noteId) are consistently passed through Zapier to maintain reliable relationships.
Build complex automations without writing a line of code and connect data across GHL and Zapier instantly.
Maintain centralized, consistent data across all apps in your stack with real-time or scheduled syncs.
Test, refine, and deploy workflows quickly using visual builders and ready-made templates.
Core elements include endpoints, authentication, data mapping, and automated workflows that move data between GHL and Zapier without custom code.
An API is a set of rules that allows software components to communicate with each other over a network.
A real-time mechanism for sending event data from one system to another when something changes.
An authorization framework that enables apps to obtain limited access tokens to another service without sharing credentials.
A specific URL path at which an API exposes a resource for reading or modifying data.
Capture leads from your website forms and push them as new contacts into GHL, then kick off follow-up tasks and notes automatically via Zapier.
Create tasks for new or updated contacts and mirror notes in your PM tool to keep teams aligned without manual data entry.
Automatically push contact segments and activity logs to your data warehouse or BI tool for deeper analytics.
Generate or obtain your GHL API credentials and establish a new connection in Zapier to authorize access to contacts, tasks, notes, and more.
Specify the endpoints you’ll use (read/write as needed), map fields, and run tests to ensure data flows correctly between GHL and Zapier.
Create Zaps that trigger on contact events and perform desired actions in GHL, then enable and monitor the workflow.
You don’t need to write code to connect GHL to Zapier. The Zapier App Connector and Webhooks allow you to configure triggers and actions using visual builders. Start with read-only operations to verify data flow before enabling write permissions. This approach helps you validate mappings and reduces risk as you scale your automations. If you are comfortable with basic API concepts, you can also test endpoints directly in Zapier’s test mode to confirm that data is appearing as expected in your connected apps.
GHL supports API keys/OAuth for authentication. In most setups, you’ll use a Bearer token in the Authorization header. Choose OAuth if you want user-based consent and token refresh, or API keys for simpler, token-based access with fixed scopes. Ensure your token has the required scope, such as contacts.readonly for reads and contacts.write for writes.
Begin with the GET /contacts/:contactId endpoint to confirm you can read a contact. Then extend to related resources like tasks (/contacts/:contactId/tasks) and notes (/contacts/:contactId/notes). After that, try creating a new contact with POST /contacts/ and updating it with PUT /contacts/:contactId to validate write capabilities.
Use Zapier’s test feature within your Zap to run a quick pull of a contact and its related data. Check the data mapping in your Zap to ensure fields align. Review authentication logs and monitor the webhook payloads to confirm successful delivery and correct field values.
Yes. A single Zap can have a trigger that reads data and actions that update GHL records. For example, when a contact is updated in your CRM, a Zap can update the corresponding GHL contact, create or update tasks, and add notes in one workflow.
GHL API usage is subject to rate limits. Plan typical business workloads with some headroom for burst traffic. If you hit limits, implement backoff logic or staggered polling in Zapier to maintain reliable operations without errors.
Full endpoint docs and usage guides are available in the GHL API reference and the Zapier App Connector docs. The endpoint list in the content above summarizes the core calls you’ll use to read and write contacts, tasks, notes, and related resources.
Due to high volume, we will be upgrading our server soon!
