Use OAuth 2.0 with an API key to securely authorize requests from Zapnito to the Contacts API. Obtain your client credentials in GHL, then exchange tokens in Zapnito for each session.
Configure Zapnito to store and rotate API tokens for the Contacts API. Use the Zapnito connector to pass your OAuth token in the Authorization header.
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
Trigger: GET /contacts/:contactId
Actions: fetch contact data, then fetch related tasks, notes, and appointments to build a complete contact profile.
GET /contacts/:contactId
contactId; include=tasks,notes,appointments
Trigger: POST /contacts/ followed by POST /contacts/:contactId/tasks
Actions: create contact, then create a starter task and assign relevant tags.
POST /contacts/; POST /contacts/:contactId/tasks
name, email, phone; after creation, task title
Trigger: PUT /contacts/:contactId and PUT /contacts/:contactId/tasks/:taskId/completed
Actions: update contact fields, then mark a task as completed.
PUT /contacts/:contactId; PUT /contacts/:contactId/tasks/:taskId/completed
contactId; updated fields; taskId; completed

A concise glossary of essential terms for integrating Zapnito with the Contacts API.
A URL path and HTTP method used to access or manipulate resources in an API.
Proof of identity used to authorize API requests and protect data.
The industry-standard protocol for obtaining access tokens to authorize API calls.
The maximum number of API calls allowed in a given time window.
Fetch or create contacts during user signup, then send a welcome task and notes to the new contact.
Aggregate contact data from multiple endpoints into a single Zapnito dashboard view.
Schedule recurring GET /contacts/:contactId/tasks checks and notify teams when tasks are overdue.
Create a GHL OAuth client for Zapnito to obtain client ID and secret.
Set scope to contacts.readonly initially; add contacts.write or full access as needed.
Test API calls in a staging environment, then deploy to production with token rotation and monitoring.
Start by registering the Zapnito app in GHL to obtain a client ID and secret, then configure OAuth in Zapnito to authorize requests against the Contacts API. Begin with the read-only scope to explore data safely. Next, test a simple GET call like GET /contacts/:contactId to verify connectivity, then expand to related endpoints for tasks, notes, and appointments as needed.
No heavy coding is required thanks to the no-code connectors and REST endpoints exposed by the GHL Contacts API. The Zapnito app configuration handles the authentication and request routing. If you need custom logic, you can add simple Zap steps to transform fields, but the core setup remains configuration-first.
Core endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to retrieve tasks, and POST /contacts/ to create new contacts. You can also extend with notes, appointments, and tags as your workflow requires.
Authentication uses OAuth 2.0 with access tokens, rotated regularly for security. Always pass the token in the Authorization header. GHL provides refresh tokens as needed; ensure your Zapnito connector handles token refresh automatically to avoid downtime.
Test calls in a staging environment using sandbox data; verify responses, status codes, and error messages. Use mock data for fields like name, email, and task titles to validate workflows before going live.
If you hit a rate limit, implement exponential backoff and respect Retry-After headers; stagger requests across steps. Monitor logs in Zapnito and GHL to identify bottlenecks and adjust permissions or batching accordingly.
Yes. You can automate retrieval of contacts, tasks, notes, and appointments across Zapnito projects by chaining endpoints in Zapier or Zapier-like connectors. Combine triggers and actions to create end-to-end workflows, such as creating a contact when a form is submitted and then scheduling a task.
Due to high volume, we will be upgrading our server soon!
