Authenticate to the Contacts API on GHL using OAuth 2.0 with scopes including contacts.readonly. Configure your Zapier connection to send a valid access token with every request.
EZLynx uses its own OAuth 2.0 flow to grant access to contact data. When you connect through Zapier, you authorize EZLynx to access Contacts data from GHL. The connection token is stored securely.
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; 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; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/tags

Key fields: contactId, firstName, lastName, email, phone
Trigger: Retrieve a contact’s tasks with GET /contacts/:contactId/tasks
Actions: Create or update tasks using POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, and mark completed with PUT /contacts/:contactId/tasks/:taskId/completed
Endpoint paths: GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId
Key fields: taskId, title, status, dueDate
Trigger: Read notes for a contact with GET /contacts/:contactId/notes
Actions: Create and read notes using POST /contacts/:contactId/notes and GET /contacts/:contactId/notes/:id
Endpoint paths: GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id
Key fields: id, note, createdAt
Faster data syncing between EZLynx and GHL via real time endpoints and Zapier automation.
No code required to set up workflows; use prebuilt triggers and actions.
Centralized customer view with contacts, tasks, notes, and appointments in one place.
This glossary explains terms used in the EZLynx to GHL integration, including OAuth 2.0, endpoints, scopes, and data fields.
OAuth 2.0 is the authorization framework used to grant secure access to GHL APIs via tokens.
An API endpoint is a specific URL path used to access data, such as GET /contacts/:contactId.
Scope defines the level of access granted, for example contacts.readonly.
Authentication verifies identity and authorizes requests to GHL APIs, typically via OAuth tokens.
Set up a Zap to create a new GHL contact whenever EZLynx receives a new lead, including basic contact details and a kickoff task.
Every time a note is added in EZLynx, automatically create a corresponding note on the GHL contact to preserve history.
When a contact or lead updates, generate or complete related tasks in EZLynx using the tasks endpoints.
Register the EZLynx app in GHL’s developer portal and obtain client ID and secret, then configure OAuth in Zapier.
In Zapier, choose the Contacts API endpoints you need (eg GET /contacts/:contactId, GET /contacts/:contactId/tasks) and map fields.
Create your Zap, test data flow between EZLynx and GHL, and monitor for errors.
Yes. The Contacts API on GHL uses OAuth 2.0 tokens to authorize requests. You can read contact data with GET endpoints under the scope contacts.readonly. When you connect via Zapier, you authorize the app to access your GHL data and requests are made with a secure access token. If you need to modify data, you must request higher level permissions or use write endpoints and ensure the necessary scopes are granted.
Reading data is straightforward with GET endpoints such as GET /contacts/:contactId and GET /contacts/:contactId/tasks. Writing data requires appropriate permissions and the corresponding endpoints (POST, PUT). Always test changes in a safe environment and monitor for errors. Ensure you comply with data privacy and security requirements.
The available endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and more as listed in the endpoint list. For writes, endpoints include POST /contacts/, POST /contacts/:contactId/tasks, PUT /contacts/:contactId, PUT /contacts/:contactId/tasks/:taskId, and DELETE /contacts/:contactId.
Rate limits are determined by the GHL API plan and your Zapier plan. If you hit limits, implement backoff and retries. Best practice is to batch requests when possible and stagger automation to avoid bursts.
The Contacts object returns fields such as contactId, firstName, lastName, email, phone, and other standard contact data. Notes and tasks are separate resources with their own IDs and fields such as id, note, title, and status.
In Zapier, credentials can be stored securely using OAuth 2.0. Use the built in authentication and refresh token support. Never hardcode tokens; rotate credentials regularly and monitor access logs.
Endpoint paths and examples are documented in the EZLynx Contacts API section and in the endpoint list above. You can copy paths like GET /contacts/:contactId and POST /contacts/. For hands on examples, build a test Zap and observe the data mapping in Zapier’s UI.
Due to high volume, we will be upgrading our server soon!
