Performs a standalone credit (general credit) returning funds to a customer without referencing an original sale. Only available when the merchant's gateway supports the general credit feature; otherwise returns a 400 error. Prefer refund routes when reversing a known prior transaction.
Use Cases: Goodwill adjustments, manual payouts where an original transaction does not exist.
Restrictions & Considerations:
- Gateway must permit general credits; feature is rarely enabled by default.
- May trigger higher fraud scrutiny; velocity limits can apply.
- Amount must be >= 0.01.
- Inventory adjustments:
meta.update_inventoryindicates stock changes (often inverted).
Differences vs Refund:
- Refund references a prior sale; credit does not.
- Settlement tokenization is not required for credit.
Security: ApiKeyAuth or EphemeralAuth.
Errors: 400 gateway reject, 422 validation, cancellation by user.
Polling & Receipts: Same as charge.
General credits are risky, and therefore not allowed for every merchant account. It is recommended to correlate any credits to an original transaction by performing a refund or void instead. For more information about general credits for your account, please reach out to support.
