How to Connect Hunter to Contacts API

Integrate Contacts API with Hunter for seamless data flow.

Step-by-step guide to link Contacts API with Hunter.

This guide walks you through securely connecting the Contacts API to Hunter so you can sync contact data, tasks, notes, and appointments without writing code.

Authentication for Contacts API

To access the Contacts API, your Hunter app must authenticate with GHL using the OAuth credentials or API key with the scope: contacts.readonly. Always request the minimum needed permissions and store tokens securely.

In Hunter, configure the connection by selecting the Contacts API (GHL) and providing your OAuth client credentials or API key. Test the connection with a simple read request to ensure access is working before enabling full automation.

Frequently Asked Questions

Do I need to write code to connect Hunter with the Contacts API?

No-code is a core benefit of this integration. You can set up triggers, actions, and field mappings using a visual editor in Hunter. The workflow builder handles API calls to the Contacts API behind the scenes. If you encounter an issue, you can test each step individually to validate data flow. Additionally, ensure your app has the correct scope (readonly) and that your credentials are kept secure in your vault.

The primary endpoints include retrieving contacts, their tasks, notes, and appointments, plus creating and updating contacts and tasks. You can also fetch business-scoped contact data. Use the ENDPOINTLIST to review specific methods and paths and map them to your Hunter steps.

Start by checking authentication status and ensuring the access token is valid. Review recent activity and any error messages in Hunter’s logs. If a sync fails for a specific contact, inspect the relevant endpoint response for missing fields, permission errors, or rate limits, then re-run the integration.

Read operations pull contact records, their tasks, notes, and appointments. Depending on the integration, you may also fetch business associations. The data fields typically include identifiers, names, emails, and timestamps for tracking changes.

Yes. You can write back to GHL to update contacts, create tasks, or add notes, subject to the assigned permissions. Map fields carefully to ensure the target records reflect the source data accurately.

Credentials are stored securely via OAuth or API keys, with access scoped to the minimum necessary permissions. Rotate tokens regularly and use secure vaults. Hunter should log all connection activities and alert you to unusual events.

Logs are accessible within Hunter’s diagnostics panel. You can filter by endpoint, status, and timestamp, export details for troubleshooting, and replay failed calls in a controlled test environment.
