Monzo

Monzo API

The Monzo API is a REST interface over a user's Monzo account. It exposes accounts, balance, savings pots (with deposit/withdraw), transactions (list, retrieve, annotate with metadata, expand merchant), feed items, attachments, transaction receipts, and webhooks for real-time transaction.created notifications. Authentication is OAuth 2.0 (authorization code grant) with Strong Customer Authentication approved in the Monzo mobile app; all requests carry a Bearer access token.
