Authenticate requests using Bearer tokens over HTTPS. Include the Authorization header with a valid token and rotate credentials regularly. Use the scope that matches your operation (e.g., contacts.readonly for reads, contacts.write for creates or updates).
Passion-io uses partner API tokens for integrations. Generate a token in your developer portal, assign the minimal required permissions, and include it in all requests to the Contacts API.
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

Powerful automations: build workflows without writing code.
This glossary defines core terms and processes used in the GHL Contacts API and Passion-io integration.
A Contact represents a person in your CRM with linked tasks, notes, and appointments.
An Action item associated with a Contact to be completed by a user or system.
A Note is a text entry attached to a Contact for contextual information.
A specific API URL path used to perform operations.
Trigger a welcome sequence in Passion-io when a new contact is created in the GHL Contacts API.
Create guided tasks for new contacts to help them explore Passion-io content and features.
Tag and group contacts based on notes to tailor messaging and campaigns.
Create API keys in both GHL and Passion-io developer portals and save securely.
Set the Contacts API scope to read-only for reporting and enable write permissions where needed (notes, tasks).
Map fields such as contactId, email, and name; run test calls to verify data flow between GHL and Passion-io.
Authentication is typically done via Bearer tokens over HTTPS; include the Authorization header with a valid token and rotate credentials regularly. Use the scope that matches your operation (e.g., contacts.readonly for reads, contacts.write for creates or updates). For Passion-io, set up a service account or partner token and test against a sandbox before going live; ensure you limit permissions to what is needed.
For syncing a contact’s tasks and notes, focus on endpoints like GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes, along with GET /contacts/:contactId to pull profile data. Map the returned fields to Passion-io’s data model and handle pagination if needed. Combine these endpoints in a workflow to keep tasks and notes in sync with the contact profile, updating Passion-io when changes occur in GHL.
Yes, you can write data back to GHL using endpoints such as POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, and POST /contacts/:contactId/notes. Ensure the token has the appropriate write scope and validate responses before proceeding to the next step. Implement robust error handling and logging, and consider using idempotent requests where supported to prevent duplicate records.
Respect API rate limits by implementing exponential backoff and retry logic on 429 responses. Monitor rate limit headers (if provided) and throttle requests accordingly to avoid failures. Batch requests when supported and consider queuing changes to smooth bursts of traffic between GHL and Passion-io.
Visit the GHL and Passion-io developer portals for API docs, sandbox environments, and changelogs. Use the official guides to understand authentication, endpoint usage, and best practices. If you need more help, contact support for technical assistance and examples tailored to your setup.
