Overview

If your application doesn’t use PostgreSQL, you can sync contacts with Minimo using our REST API. Every time a user is created or updated in your app, you call the Minimo API to keep contacts in sync.
Using PostgreSQL or Supabase? We recommend the native Supabase Connection instead — it’s plug-and-play, requires no code, and has no API failure points.

​
How it works

  1. On app startup: ensure your custom fields exist in Minimo
  2. On user create/update: call the upsert endpoint to sync the contact
  3. On user delete (optional): call the delete endpoint to remove the contact
The upsert endpoint handles both creation and updates automatically, matching contacts by email or phone.

​
Implementation

​
Use an AI coding tool

The fastest way to implement API sync is with our ready-made AI prompt. Give it to your AI coding tool (Cursor, Claude, Lovable, V0, Replit) and it will generate the full integration for you.

Contact Sync AI Prompt

Ready-to-use prompt that generates a complete contact sync integration with custom field setup, upsert logic, and lifecycle hooks.

​
Build it manually

If you prefer to implement it yourself, refer to the API reference:

Upsert Contact

Create or update a contact by email or phone.

Custom Fields
