GHL API uses OAuth 2.0 with access tokens. You will create a developer application in GHL, then authorize the Zapier App Connector to access your account. Use your client ID, client secret, and redirect URI to complete the flow.
Zapier App Connector handles token exchange behind the scenes. When you connect the GHL API, you’ll sign in once and Zapier stores a secure token for API calls.
Common endpoints include: create/update contacts, fetch deals, manage tasks, sync notes, and fetch activity. In a no-code context, you’ll primarily use POST, GET, PATCH, and DELETE operations on resource paths like /contacts, /deals, /tasks, and /notes.
Trigger: A new form submission or lead event creates or updates a contact in GHL via the API.
Actions: Create or update contacts, add notes, attach deals, and push updates to GHL timelines.
Endpoint paths: POST /contacts to create, PATCH /contacts/{id} to update, GET /contacts/{id} for retrieval.
Key fields: email, first_name, last_name, phone.
Trigger: A new deal is created or updated in your CRM to reflect in GHL as a deal record.
Actions: Create or update deals, set stages, assign to contacts, add notes.
Endpoint paths: POST /deals, PATCH /deals/{id}, GET /deals/{id}.
Key fields: deal_name, amount, close_date, contact_id.
Trigger: An event in your project tool creates a corresponding task in GHL.
Actions: Create tasks, set due dates, assign to contacts, and link to deals or projects.
Endpoint paths: POST /tasks, PATCH /tasks/{id}, GET /tasks/{id}.
Key fields: task_name, due_date, assignee_id, related_contact_id.
Automate data flow between GHL and your apps without writing code.
Enable rapid prototyping and iteration with drag-and-drop automation.
Rely on proven, auditable processes with logs and built-in error handling.
This glossary defines common terms used in GHL API integrations and describes data elements and processes.
An individual URL path and HTTP method used to perform a specific operation on GHL data.
The process of proving identity and permissions to access GHL data, typically via OAuth 2.0 tokens.
A callback URL you can subscribe to to receive real-time events from GHL.
The maximum number of API requests you can make in a given time window.
Automatically create or update contact records in GHL when a form is submitted in another app, keeping data in sync without manual entries.
Push deal milestones from your CRM into GHL to keep sales stages aligned and visible in one place.
Automatically create tasks and reminders in GHL when project management tools update, ensuring timely follow-ups.
In GHL, create an API key or OAuth client and note your client ID and secret.
Connect the GHL API by providing client ID, client secret, and auth URL; authorize the app to access your GHL account.
Run a test to fetch sample data, map fields, and enable your automation.
The GHL API exposes programmatic access to core data such as contacts, deals, tasks, and notes. When used with the Zapier App Connector, you can trigger actions in GHL from other apps and push data back to your workflows. This enables seamless no-code automation across your stack. In practice, you’ll design flows that read from source apps, map fields to GHL records, and perform create, update, or delete operations as needed.
No coding is required to build these automations. Drag-and-drop steps, built-in actions, and pre-built connectors let you orchestrate data between GHL and your apps. If you know basic logic (conditions, filters, and mappings), you’ll be productive in minutes.
Authentication is handled via OAuth 2.0 tokens or API keys, depending on your setup. Keep client secrets secure, rotate tokens regularly, and use Zapier’s secure storage for credentials. Re-authenticate if connections become invalid.
Yes. Field mapping lets you align data between GHL and other apps. For example, map contact email to the email field, names to first_name and last_name, and map deal values to deal_amount. Test mappings to ensure data quality.
If a connection fails, check credentials, network access, and token validity. Review task history and error messages in the Zapier app, re-authenticate if needed, and re-run the test to confirm resolution.
Rate limits apply to API calls. Plan your automation to minimize requests, batch operations where possible, and implement retries with backoff. Monitor usage via the GHL developer console and Zapier task history.
Documentation for the GHL API is available in the GHL developer portal. Look for guides on authentication, endpoints, rate limits, and error handling. If you need, you can also consult the Zapier App Connector docs for flow examples.
Due to high volume, we will be upgrading our server soon!
