  title: Paymob Accept Legacy (v2) Accounts Payment Keys API
  version: '2.0'
  description: 'The legacy Paymob Accept API uses a three-step flow: authenticate to receive a bearer auth_token, register an order, then request a payment_key. The payment_key is used either with the iframe redirect or the headless /payments/pay endpoint. Refund, void, capture, transaction inquiry, and saved-card MOTO operations are exposed on this surface.'
