How to connect Blink to the Contacts API

Contacts API x Blink: Seamless data flow for contacts, tasks, notes, and appointments

Connecting the Contacts API with Blink

This guide shows how Blink uses the Contacts API to read your contact data across endpoints like contacts, tasks, notes, and appointments. It covers authentication, endpoint usage, and best practices for reliable data sync between GHL and Blink.

Authentication for the Contacts API

Blink authenticates to GHL via OAuth 2.0 with the contacts.readonly scope to securely retrieve data. Use the standard redirect flow to grant permissions and refresh tokens as needed.

Authentication for Blink

Blink will request access to GHL using OAuth. Authorize Blink in your GHL account to enable data pulls of contacts, tasks, notes, and appointments.

Available endpoints at a glance

Primary read-only endpoints include: 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. Use these to fetch, read, and map contact data into Blink.

Step 3: Test, validate, and go live

Run tests, confirm data flows, and enable scheduled sync for ongoing updates.

Frequently asked questions

Do I need coding to set this up?

No coding is required. The Blink setup uses a guided OAuth flow to connect to your GHL account, and you configure which data to pull through a user-friendly interface. If you already connected, you can re-authenticate or adjust scopes anytime. Two-factor steps may be involved depending on your org’s security settings. The interface is designed for non-developers to get up and running quickly.

Blink can access core contact data from GHL, including contacts, their tasks, notes, and appointments within the permitted scope. You can also pull business associations for broader context. Custom fields can be mapped to Blink for consistent data presentation.

Security is built on OAuth 2.0 with token-based authentication and scoped permissions. Access tokens are stored securely, and you can revoke Blink’s access at any time from your GHL account. Data transfer uses encrypted channels to protect information in transit.

Yes. The integration allows you to select which endpoints to sync and map specific fields. You can disable certain data streams or adjust field mappings without writing code, giving you control over what data moves between GHL and Blink.

If a sync fails, check the OAuth status, permission scopes, and endpoint availability. Blink provides logs and error messages with actionable steps. You can re-run the sync from the dashboard after addressing any issues.

Real-time updates depend on endpoint support and webhooks. Read-only access can still sync on a schedule, and some event-driven updates may be available if you enable webhook notifications from GHL. Check your plan and settings for live updates.

To disconnect, go to Blink settings, choose Disconnect from GHL, and confirm. This will revoke Blink’s access to your GHL data. You can re-connect later if needed, re-running the setup from the beginning.
