Backend Payment Creation

Mint payments should be created on your backend, never in the browser.

Create a payment

Send a POST request to /v1/payments.

For customer integrations, use the production Mint API base URL and a test checkout when validating the flow.

Practical guidance

• Validate amount and currency before calling Mint.
• Keep your secret key in server-side environment variables only.
• Attach your own order and customer references at payment creation time.
• Persist the Mint payment ID in your own system for reconciliation.
