Cards are a widely supported payment method that allow payers to complete payments instantly using credit or debit cards.
They provide a fast, familiar experience and are typically the default choice for one-time or immediate payments.
How cards work
Card payments follow a simple flow: collect details, authorize, and capture funds.
-
Collect card details
Card information is collected through a hosted page or embedded element.
-
Authorize payment
The payer’s bank approves or declines the transaction in real time.
-
Complete payment
Funds are captured and the payment is marked as successful.

When to use cards
Cards are best suited for:
- One-time payments
- Immediate payment confirmation
- Payers who expect a familiar checkout experience
- Global payment acceptance
Authorization and settlement
Card payments are authorized immediately, but settlement may occur later depending on the network and region.
- Authorization — real-time approval or decline
- Settlement — funds are transferred after processing
Setup and reuse
Cards can be securely stored and reused through setup requests.
This allows you to:
- Avoid re-collecting card details
- Enable faster repeat payments
- Support off-session payments
Sensitive card data is not exposed to your systems.
Failures and declines
Failed payments may fail during authorization.
See Payment failures for failure codes and guidance on retrying.
Common reasons include:
- Insufficient funds
- Incorrect card details
- Card restrictions or blocks
Failed payments can typically be retried immediately after correcting the issue.
Disputes
Card payments may be disputed by the payer after completion.
Disputes:
- Are initiated through the card network
- Require evidence and response
- May result in funds being reversed
See Disputes for more.
Best practices
- Offer cards for fast and familiar payment experiences
- Use setup requests for repeat payers
- Handle declines gracefully and allow retry
- Monitor disputes and respond promptly
Summary
- Cards provide instant authorization and global coverage
- They are ideal for one-time and immediate payments
- Setup requests enables reuse and faster repeat payments
- Disputes and declines should be handled as part of normal operations
