Authorization reversal

An authorization reversal is a message a merchant sends to release a hold that a previous card authorization placed on a customer's account, in full or in part, before the transaction is captured. It tells the issuing bank that some or all of the authorized amount will not be charged, so the held funds can be freed.

A reversal matters because a card authorization does not just check that funds exist; it sets them aside, reducing the customer's available balance or credit until the hold clears. If the merchant will not collect part or all of that amount, reversing the authorization returns the held funds quickly rather than leaving the customer waiting for the hold to expire on its own. This is different from a refund, which returns money that has already been captured and settled. Recurly doesn't have a distinct authorization-reversal feature. Its own mechanism for releasing a held authorization is a full void, covered on the Void glossary page, and it doesn't release only part of a hold.

Why authorization reversal matters for subscription businesses

The customer experience is the main reason to reverse promptly. A lingering hold ties up money the customer cannot use, and stale holds are a common source of confused billing questions and complaints. Reversing an authorization the merchant will not capture, or reversing the unused portion of one, resolves that quickly and keeps trust intact.

There can be a cost angle as well. Leaving authorizations open or capturing an amount different from what was authorized can, depending on network rules, carry fees or affect interchange qualification. Reversing cleanly when plans change is good payment hygiene. For a subscription business, the most common cases are a failed or abandoned sign-up, a duplicate authorization, or a final charge that comes in lower than the amount first held.

How authorization reversal works

A reversal acts on an authorization that has not yet been captured:

1. The merchant holds an authorization on the customer's card for an expected amount.

2. The merchant determines it will not capture the full amount, because the sale changed, failed, or came in lower.

3. The merchant sends a reversal request to the processor, for the whole authorization or for the unused portion.

4. The issuer releases the held funds, restoring that amount to the customer's available balance.

5. If part of the transaction is still due, the merchant captures the remaining amount as normal.

A full reversal releases the entire hold, while a partial reversal releases only the amount that will not be charged. Recurly supports the full-release case through voiding an authorization; it does not support releasing only part of a hold.

Benefits and examples

Sending authorization reversals promptly has practical benefits:

• A better customer experience, because held funds are freed instead of lingering until the hold expires.

• Fewer billing complaints, since customers are not left asking about a hold for a charge that will not happen.

• Cleaner payment operations, avoiding open or mismatched authorizations that can carry fees under network rules.

• Accurate holds, when a partial reversal aligns the held amount with the final charge.

As an illustration of the general concept, consider a hypothetical merchant that authorizes 100 dollars for an order, then finds one item is out of stock and the real total is 60 dollars. In a system that supports partial reversals, the merchant would release the 40 dollar difference and capture 60 dollars, so the customer sees 40 dollars freed and is charged only what shipped. Recurly doesn't support this. More broadly, capturing less than the authorized amount is generally limited to specific categories like travel, fuel, and car rental, none of which are among the subscription use cases Recurly supports. On Recurly, that merchant would need to void the full 100 dollar authorization, then obtain and capture a new authorization for the correct 60 dollars.

Frequently asked questions

What is an authorization reversal? It is a message that releases a hold placed by a prior card authorization, in full or in part, before the transaction is captured. It tells the issuer that some or all of the authorized amount will not be charged, so the held funds are freed.

What is the difference between an authorization reversal and a refund? A reversal releases funds that were only held by an authorization and never charged. A refund returns money that has already been captured and settled. A reversal is generally faster for the customer because no money changed hands yet.

Why would a merchant reverse an authorization? Common reasons include an abandoned or failed checkout, a duplicate authorization, or a final amount that is lower than the amount first held. Reversing frees the customer's held funds and keeps payment records clean.

Can only part of an authorization be reversed? In some systems, yes: a partial reversal releases only the portion that will not be charged, leaving the rest of the authorization in place to be captured. Recurly doesn't offer this, and more generally, capturing less than the authorized amount isn't available to Recurly's subscription merchants at all, since card networks limit that pattern to specific categories like travel, fuel, and car rental. If the final amount comes in lower than what was authorized, the merchant voids the original authorization, then gets and captures a new authorization for the correct amount.
