Preview. The Payments API (V3) is live at
https://api.tagada.io/v1, but it is not open to self-serve integrations yet: merchant secret keys cannot be created from the dashboard. Every merchant processes on V2 today. Contact api-support@tagadapay.com if you plan a new integration.2026-11-01. It lists the endpoints available to secret and publishable keys.
Each endpoint lists the scopes it needs (
x-scopes) and whether a publishable key may call it (x-publishable). A publishable key can only call endpoints marked publishable, and only for the payment whose client_secret it sends.
The Payments-Account header is for platform keys only. Do not send it with a secret or publishable key.
Endpoints reserved to TagadaPay operators are not listed.
