Authorize requests to the Contacts API with OAuth 2.0 or an API key. Use the required scope: contacts.readonly to view data, and switch to a broader scope if you need write access.
Within NinjaPipe, link your GHL Contacts API connection by supplying credentials and securely storing tokens. NinjaPipe will attach the proper authorization header to every request.

POST /contacts/, POST /contacts/:contactId/tasks
Contact fields: name, email; Task fields: title, dueDate
Trigger: on note or appointment events to keep NinjaPipe updated

GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments
Notes: notesId; Appointments: appointmentId; Contact: contactId
Automate data flow between NinjaPipe and your Contacts data without writing code.
Consolidate contacts, tasks, notes, and appointments into unified workflows.
Real-time sync and reliable triggers for timely follow-ups.
A quick glossary of terms used in this guide to help you understand endpoints, authentication, and data mapping.
A specific URL in a web API that performs a defined action on a resource.
The process of proving identity and permissions to access an API (OAuth or API key).
An entity exposed by the API, such as a contact, task, note, or appointment.
A callback URL that lets the API notify your app of events in real time.
Automatically import contacts in batches and keep tasks and notes in sync as changes happen.
Create follow-up tasks or notes when trigger events occur, ensuring timely outreach.
Link notes to related tasks and appointments to preserve context in workflows.
Obtain OAuth tokens with the required scopes and securely store them.
Define data mappings between Contacts API fields and NinjaPipe fields; choose endpoints you will use.
Run tests, verify data flow, and set up alerts for failures.
Authentication uses OAuth 2.0 or API keys. Start by creating a connected app in GHL and granting the NinjaPipe app the ‘contacts.readonly’ scope. Exchange the authorization code for tokens and attach them to requests. Securely store refresh tokens to maintain access.\nWith the appropriate scope, you can upgrade to write access when needed.
Read-only endpoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, GET /contacts/ and GET /contacts/business/:businessId. Write operations require the contacts.write scope and include POST, PUT, DELETE endpoints such as POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, and more.\nAlways map scopes to the level of access you truly need and monitor usage.
Yes. If you have the contacts.write scope, you can create or update contacts via POST /contacts/ and PUT /contacts/:contactId. Ensure required fields are provided and that mappings align with your NinjaPipe data model.\nFor updates, use the contactId to locate the correct record and apply the changes you need.
Handle errors by inspecting HTTP status codes and API error messages in the response body. Implement retry logic with exponential backoff and log failures for troubleshooting.\nStore error details in NinjaPipe to help with support tickets and data hygiene.
Rate limits vary by plan and endpoint. Check response headers for remaining quota and reset times. If you approach limits, stagger requests, batch operations where possible, and prioritize essential data fetches.\nConsider using bulk or cached data strategies to reduce calls.
Basic HTTP and JSON understanding is helpful. No heavy coding is required if you use NinjaPipe’s no-code/low-code connectors. Some field mapping and endpoint selection will speed setup and improve data accuracy.\nAdvanced users can build custom transformations and error handling rules as needed.
NinjaPipe will surface the connected data in its dashboards, lists, and task/notes views. Use filters and mapping to align CRM data with your workflows for clear visibility.\nYou can also set up alerts to monitor changes in contacts, tasks, notes, or appointments.
Due to high volume, we will be upgrading our server soon!
