How to Connect CloudCart with the Contacts API

This guide walks you through authenticating, selecting endpoints, and building reliable, automated workflows between CloudCart and the Contacts API.

Authentication for the Contacts API

Authorize requests using your GHL API credentials with the required scope: contacts.readonly. Use OAuth 2.0 tokens or an API key as configured in your GHL developer settings.

CloudCart App Authentication

Secure CloudCart by validating requests against your GHL account. Store credentials safely, rotate keys regularly, and follow least-privilege access.

Frequently Asked Questions

What is the Contacts API in this integration?

The Contacts API is the bridge between CloudCart and your contact records. It exposes read endpoints to fetch contact details, notes, tasks, and more. By using the API, you can keep CloudCart up-to-date with the latest contact information. This integration leverages secure authentication and proper scopes to protect data access while enabling automated workflows between systems.

To authenticate, use the GHL API credentials issued for your app, including the client_id and client_secret. The flow may use OAuth 2.0 tokens or API keys depending on your setup. Ensure the access token includes the required scope contacts.readonly. Store tokens securely and rotate them periodically to reduce risk.

Common endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to fetch tasks, and POST /contacts/ to create a new contact. Depending on your workflow, you may also use notes, appointments, and tagging endpoints. These endpoints cover typical read and write operations used in syncing CloudCart data.

Yes. You can read and write contact data through the allowed endpoints (GET, POST, PUT, DELETE). The access level depends on your OAuth scope and app permissions. Best practice is to test thoroughly in a staging environment before going live.

No code is required for basic synchronization. Use pre-built automations and the connector in Zapier or your integration tool. For advanced flows, you may add custom mappings.

Handle errors by inspecting API response codes, implementing retries with backoff, and logging failures. Use webhooks or event-based triggers where possible to recover gracefully and maintain data integrity.

There are rate limits per API plan. If you exceed quotas, responses will return error codes; space out requests, implement caching, and design idempotent operations to avoid duplicates.
