How to Connect MailingVox to Contacts API

A practical guide to linking the Contacts API with MailingVox for seamless data flow

Steps to connect MailingVox with the Contacts API

This guide explains how to authorize and connect MailingVox with the Contacts API (GHL) using the scope contacts.readonly, outlining authentication, endpoint mapping, and recommended workflows for syncing contacts, tasks, notes, and appointments.

GHL Contacts API authentication

Authenticate using OAuth 2.0 with a read-only scope to access contacts data. Obtain client credentials from your GHL developer portal and securely exchange access tokens for API calls.

MailingVox authentication

Protect your MailingVox API credentials, rotate keys regularly, and connect through secure OAuth or API key methods provided by MailingVox for seamless integration.

Top 3 connection patterns between MailingVox and the Contacts API

1) Lead capture to contact creation

Trigger: MailingVox receives a new or updated lead and creates or updates a corresponding contact in the Contacts API.

Actions: Create or update the contact with core fields (name, email, status); optionally create a follow-up task or note.

Use POST /contacts/ to create or PUT /contacts/:contactId to update, ensuring unique identifiers like email are used.

Frequently Asked Questions

Do I need to code to connect MailingVox with the Contacts API?

No heavy coding is required for a basic integration. You can connect MailingVox to the Contacts API using OAuth 2.0 authentication and map essential fields like name and email through the UI. Start with a read-only access that validates data flow before enabling write operations. If you need more control, you can progressively add endpoints and tasks as you gain confidence.

For a basic sync, focus on creating contacts and mirroring key fields (name, email, status). Optional but common endpoints include tasks and notes to capture activity. Start with GET /contacts/:contactId and POST /contacts/ to establish a foundation, then expand to notes and tasks as needed.

Use OAuth 2.0 to authenticate and request a scoped access token. Keep credentials secure, rotate keys regularly, and implement token refresh logic. Avoid embedding secrets in client-side code and prefer server-side calls with proper encryption.

Yes. Webhooks can be used to push real-time updates from MailingVox to the Contacts API and vice versa. Configure event subscriptions for contact changes, task updates, and note additions to maintain real-time sync.

Common fields include contactId, email, name, and status for contacts; taskId, title, dueDate, and status for tasks; noteId and note content for notes. Additional fields can be mapped as needed during setup.

If you encounter errors, review the API response codes and messages, verify authentication tokens, confirm endpoint availability, and check field mappings. Enable verbose logs during troubleshooting and reproduce the issue with a small data subset.
