Authorization checks that a card is valid and reserves the funds; capture is what actually moves the money. Most integrations perform both in a single call, but they are separate steps and separating them deliberately is sometimes the right choice.
What each step does
| Authorization | Capture | |
|---|---|---|
| What happens | Card validated, funds reserved | Funds actually transferred |
| Customer sees | A pending charge | A completed charge |
| Money moved | None | Yes |
| Reversible by | Voiding the auth | Refunding |
| Expires | Yes, typically ~7 days | No |
The distinction matters because a pending authorization can be voided cleanly, while a capture can only be refunded — and a refund usually costs you the processing fee and appears on the customer''s statement twice.
When to separate them
- Physical goods. Authorize at checkout, capture when the item ships. Many jurisdictions expect this, and it avoids refunding orders you cannot fulfil.
- Manual review. Hold a suspicious order, verify it, then capture or void.
- Variable final amounts. Hotels, car hire and fuel authorize an estimate and capture the actual total.
- Limited stock. Confirm availability before taking the money.
The customer-experience trap
A voided authorization does not always disappear from the customer''s statement immediately. Depending on the issuer, a pending charge can linger for days after you have voided it, which generates support tickets — and occasionally retrieval requests — for money that was never actually taken.
If you authorize and void frequently, say so at checkout. It is much cheaper than explaining it one customer at a time.
GOOD QUESTIONS
Frequently asked
How long does an authorization last?+
Typically 7 days for card-not-present transactions and up to 30 for some categories, though issuers vary. After that the hold expires and the funds return to the customer's available balance — capturing later may fail.
Does an authorization take money from the customer?+
No, it reserves it. The amount is deducted from their available credit or balance so they cannot spend it elsewhere, but no money moves until capture. Customers often see it as a pending charge and mistake it for a real one.
Can I capture less than I authorized?+
Usually yes, and it is common in ecommerce when part of an order is out of stock. Capturing more than authorized generally requires a new authorization.
Should I separate authorization and capture?+
Separate them when there is a real gap between the order and fulfilment — physical goods, manual review, or availability checks. For instant digital delivery, combining them is simpler and avoids expired-authorization failures.
