# Payment

This section covers how partners take payment through Entur's [Payments
API](/apis/payment-partner). It currently focuses on **payment agreements** — a
way to let a customer authorize you once so your backend can charge them later,
without asking them to confirm each payment.

  agreements are, what the customer authorizes, and how to create one and charge
  against it.
