Update Card

POST https://api-sandbox.letpay.io/subscriptions/SUBSCRIPTION_ID/token

This HTTP POST request is used to update the card associated with an active subscription. Use this endpoint when a payer's card has expired, been replaced, or when the merchant wants to link a different card to the recurring billing. The subscription remains ACTIVE and the next billing cycle will use the new card.

Two strategies are supported:

  • New Card: Provide the raw card details to tokenize a new card.
  • Existing Token: Reference a card already tokenized in ePag using public_person_id and public_card_id.
