All endpoints use HTTPS with Basic authentication and accept and return JSON. Endpoints are grouped by workflow: onboard merchants first, then accept payments, then move funds and report. termsOfService: https://help.jupico.com/references-and-resources/legal contact: email: support@jupico.com license: name: Jupico License url: https://jupico.com version: 1.0.5 servers: - url: https://sandbox-platform.jupico.com security: - basicAuth: [] tags: - name: Status description: Health check for the Jupico API. - name: Onboarding Invites description: >- Create and send invites that onboard merchants through the Jupico-hosted flow, with optional pre-filled identity, fees, and payout bank account data. - name: Provisioning description: >- Onboard merchants from your own UI.
