Back to the API reference

This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-10-22 22:09 UTC.

API reference Merchants

Processor Capability: lists what each of the merchant's active processor profiles can do.

GET /api/merchants/{id}/processor-capabilities deprecated

No permission required.

Example: `GET /api/merchants/3fa85f64-5717-4562-b3fc-2c963f66afa6/processor-capabilities`. Correlate each entry with the matching profile from `GET /api/merchants/{id}/processor-profiles` using `processorProfileId`. Two profiles boarded on the same processor report identical flags: capability is a property of the processor, not of the individual profile. A profile whose processor has no capability information registered reports every flag as `false`. That is deliberate: an unknown capability is reported as unsupported rather than assumed, so a caller never reads support for something the processor cannot do. Requires the merchant read permission, and answers `404` for a merchant outside the caller's scope exactly as it does for one that does not exist.

Signed in, you can send this request to your own sandbox merchant from the console and read the answer. Sign in to try it.

Body: MerchantProcessorCapabilitiesDto MerchantProcessorCapabilitiesDto Each item has these fields.

Field Type Description
merchantId required string (uuid) The merchant the capabilities were resolved for.
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
profiles required array of ProcessorProfileCapabilitiesDto array of ProcessorProfileCapabilitiesDto One entry per active processor profile, in the order the profiles are stored on the merchant. Empty when the merchant has no active processor profile, which reads the same as "nothing is supported yet": a merchant that is not boarded cannot process anything. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

Fields of each ProcessorProfileCapabilitiesDto:

Field Type Description
processorProfileId required string (uuid) The processor profile these capabilities describe. Correlates with `processorProfileId` on the processor-profiles API.
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
processorId required string The stable processor key the profile is boarded on (for example `tsys` or `fiserv`). Echoed exactly as stored on the profile, so it matches the value on the processor-profiles API. Compare it case-insensitively: the platform resolves the key that way and the stored casing is not normalized. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
processorName required string The processor's display name as stored on the profile. Presentation only: never match on this, always match on `processorId`. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
supportsZeroDollarVerification required boolean Whether this processor supports a zero-dollar account-verification authorization (authorize $0 with an AVS/CVV check, then void immediately). This is what gates the hosted payment page's "save my card, do not charge me" flow: when `false`, a save-card-only session on this processor cannot complete without an amount.
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
supportsReversal required boolean Whether the processor accepts a reversal of an authorization that has not settled.
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
reversalWindowSeconds required integer (int32) The maximum age, in seconds, an authorization may have and still be reversible, or `null` when the processor publishes no window. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
supportsVoid required boolean Whether the processor accepts a void of a transaction in the open batch.
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
supportsPartialRefund required boolean Whether the processor accepts a refund for less than the original settled amount.
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
supportsPartialReversal required boolean Whether the processor accepts a reversal that releases only part of the authorization hold. When `false`, only full-amount reversals are accepted.
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
supportedAdjustmentTypes required AdjustmentTypes AdjustmentTypes The adjustment-shaped follow-up operations the processor advertises (offline adjustment, incremental authorization, both, or none). Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
None Processor advertises no adjustment support. Both OfflineAdjustment and IncrementalAuthorization requests are rejected.
OfflineAdjustment Processor accepts TransactionOperationType.OfflineAdjustment: pre-settlement edits to the stored settlement record (tip, tax, level-3, AVS) with no network call. Modeled by OfflineAdjustmentFlowRunner.
IncrementalAuthorization Processor accepts TransactionOperationType.IncrementalAuthorization: an online amount-bumping auth on top of the existing approved hold (Visa Estimated/Incremental, MasterCard PreAuth+Final, Discover Incremental). Modeled by IncrementalAuthorizationFlowRunner.
softDescriptorNameMaxLength required integer (int32) The number of leading characters of the soft descriptor merchant name (the alternate merchant name sent on a transaction) that the processor prints on the cardholder statement. A longer name is accepted on the request and truncated by the processor. `null` when the processor declares no limit. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

429 The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause.
