# Increment an authorization

Perform an incremental authorization on an eligible [PaymentIntent](https://docs.stripe.com/docs/api/payment_intents/object.md). To be eligible, the PaymentIntent’s status must be `requires_capture` and [incremental_authorization_supported](https://docs.stripe.com/docs/api/charges/object.md#charge_object-payment_method_details-card_present-incremental_authorization_supported) must be `true`.

Incremental authorizations attempt to increase the authorized amount on your customer’s card to the new, higher `amount` provided. Similar to the initial authorization, incremental authorizations can be declined. A single PaymentIntent can call this endpoint multiple times to further increase the authorized amount.

If the incremental authorization succeeds, the PaymentIntent object returns with the updated [amount](https://docs.stripe.com/docs/api/payment_intents/object.md#payment_intent_object-amount). If the incremental authorization fails, a [card_declined](https://docs.stripe.com/docs/error-codes.md#card-declined) error returns, and no other fields on the PaymentIntent or Charge update. The PaymentIntent object remains capturable for the previously authorized amount.

Each PaymentIntent can have a maximum of 10 incremental authorization attempts, including declines. After it’s captured, a PaymentIntent can no longer be incremented.

Learn more about [incremental authorizations](https://docs.stripe.com/docs/terminal/features/incremental-authorizations.md).

## Returns

Returns a PaymentIntent object with the updated amount if the incremental authorization succeeds. Returns an error if the incremental authorization failed or the PaymentIntent isn’t eligible for incremental authorizations.
