How to Connect mloflo Contacts API to GHL

Integrate the GHL Contacts API with the mloflo app using the Zapier App Connector for automated data flows

How to Connect the Contacts API with the mloflo App

This guide walks you through authenticating, linking, and using the GHL Contacts API within the mloflo app via the GHL App Connector, enabling CRUD operations on contacts, tasks, notes, and appointments from a single workflow.

Authentication for the Contacts API

Authenticate requests to the GHL Contacts API using OAuth 2.0 and API keys. Create an app in your GHL developer portal, grant the Contacts scope, and securely store tokens.

Authentication for mloflo

To authorize mloflo to access your GHL data, configure app permissions in the mloflo developer console and connect the two systems with the credentials provided. Use OAuth clients or an API key as required by your setup, then test the connection.

FAQ

How secure is the integration?

Security is built on OAuth 2.0, encrypted connections, and scoped access. Use strong credentials, rotate tokens regularly, and store secrets securely. In practice, enable least-privilege permissions and monitor API activity with webhook logs. Regularly review access and revoke tokens when no longer needed.

Yes. Field mapping lets you customize how data from mloflo maps to GHL fields. Use standard fields like name, email, phone, and customFields. If you need nonstandard fields, create custom mappings and extend with API calls when necessary.

Most setups require read access to contacts and notes, and write access to update records. Typical endpoints include GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, and POST /contacts/:contactId/notes. You can enable only the endpoints you need to minimize surface area. Refer to the full endpoint list for details.

No coding is required. Use the GHL App Connector in a no-code flow to connect apps. If custom logic is needed, small code steps or webhooks can be added, but manyUse cases work entirely with drag-and-drop configuration.

If an API call fails, the integration should retry with exponential backoff and provide clear error logs. Implement monitoring and alerting so the team can respond quickly and fix root causes.

Historical data can be backfilled by running batch imports within a defined date window. Plan for rate limits, process data in chunks, and validate results after each batch.

The GHL API enforces rate limits. Use batching, staggered requests, and exponential backoff to stay within limits. Consider queuing and retry strategies to maintain smooth operation.
