How to connect FITR to the Contacts API

Integrating the Contacts API with FITR for a seamless data flow

Steps to connect the Contacts API with FITR

This guide walks you through authenticating, mapping fields, and using the API endpoints to sync data between FITR and the Contacts API without code.

Authentication for the Contacts API

Use your GHL API credentials to authorize requests from FITR. The required scope is contacts.readonly for read operations; you can request additional scopes for write actions when needed.

Authentication for FITR

To authorize FITR to access the Contacts API, configure OAuth or API key within FITR’s integration settings, grant the required scopes, and test the connection.

GHL Contacts API Endpoints used by FITR

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

Top 3 integration patterns between the Contacts API and FITR

1) Read contact data and update tasks in FITR

Trigger: When a contact is updated in GHL, fetch the latest data and update the corresponding contact in FITR.

Actions: Retrieve /contacts/:contactId and related /contacts/:contactId/tasks to sync status and tasks into FITR.

GET /contacts/:contactId and GET /contacts/:contactId/tasks

contactId, email, firstName, lastName, phone, taskIds

2) Create or update a contact and attach notes

Trigger: New or updated contact in FITR creates/updates a contact in the GHL Contacts API.

Actions: POST /contacts/ to create; PUT /contacts/:contactId to update; POST /contacts/:contactId/notes to attach notes.

POST /contacts/; PUT /contacts/:contactId; POST /contacts/:contactId/notes

email, name, notes content, businessId

3) Tag management and status syncing

Trigger: FITR status or tags change updates GHL contact tags

Actions: PUT /contacts/:contactId to update status; POST /contacts/:contactId/tags to apply tags.

PUT /contacts/:contactId; POST /contacts/:contactId/tags

contactId, tags, status

Three simple steps to connect the Contacts API with FITR

Register and authorize

Create GHL API credentials and authorize the FITR app to access the Contacts API.

Map fields

Test and deploy

Run tests, validate data flows, and enable the live integration.

Frequently Asked Questions

What can I access with the Contacts API in FITR?

The Contacts API in FITR lets you read contact data, tasks, notes, and appointments linked to each contact. You can also create and update contacts as needed. Start with read-only access to explore the data model, then request additional permissions if your workflow requires write actions. This keeps your data safe while you learn the integration. If you need to create or modify data (e.g., add tasks or update notes), you can request write permissions. Begin with read access to validate your setup before enabling broader permissions.

Write permissions are controlled via OAuth scopes; you should request the contacts.write scope for creating or updating resources. Ensure your FITR integration is approved by an admin before enabling write access to prevent unintended changes. For safety, start with read-only access and gradually elevate permissions as your use case demands.

Authentication typically uses OAuth with API keys or tokens. Your FITR app must be whitelisted to access the GHL Contacts API. Refresh tokens periodically and store credentials securely; rotate credentials if a breach is suspected. Always test authentication in a sandbox or staging environment before going live.

For syncing, use read endpoints to pull contact data and related tasks/notes. Writes should use POST, PUT, or DELETE endpoints as appropriate. Map fields carefully (e.g., email, name, phone) to ensure data consistency across systems. Prioritize endpoints that align with your workflow, such as GET /contacts/:contactId and GET /contacts/:contactId/tasks for read operations, and POST /contacts/ for creation when needed.

Rate limits depend on your GHL plan and API usage. Plan for bursts during initial syncs and implement exponential backoff on 429 responses. Monitor your logs and adjust request frequency to stay within allowed quotas. If you anticipate high volume, contact support to discuss higher limits or optimization strategies.

Data mapping involves aligning FITR fields with corresponding GHL fields. Start with core fields like email, firstName, lastName, and phone, then map notes, tasks, and tags as needed. Use consistent formats to avoid data mismatches and ensure timestamps are in a compatible format. Document your mapping rules so future changes are predictable and maintainable.

Yes. You can use a sandbox or test environment to validate the integration with sample data. Run end-to-end tests for read and write operations, verify data integrity, and confirm that automations trigger as expected before switching to a live connection. After successful testing, deploy the integration and monitor initial runs closely for any anomalies.
