An entry carries code when the validator declared a publishable one, and memberPaths when the full path says more than members does (an element inside a collection, for example). Both keys are omitted when they would add nothing. ```json { "error": { "code": "null", "message": "Your request is not valid!", "details": "The following errors were detected during validation.", "data": { "correlationId": "0123456789abcdef0123456789abcdef" }, "validationErrors": [ { "message": "'Amount' must be greater than 0.", "members": [ "amount" ] }, { "message": "The card has expired.", "members": [ "expirationDate" ], "code": "CardData:CardExpired" }, { "message": "'Value' must not be empty.", "members": [ "value" ], "memberPaths": [ "customFields[2].value" ] } ] } } ``` ### 404 Not Found **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) _Example: Resource not found_ The id in the path names no record the caller can see. Most resources answer with a null error.code and a message naming the resource type and the id; a resource that publishes a not-found code in the catalog above carries it in error.code instead, so check for one before matching on the message. ```json { "error": { "code": "null", "message": "There is no entity Transaction with id = 7d1f3a52-0c4e-4b8a-9e21-5a6b7c8d9e00!", "details": "null", "data": { "correlationId": "0123456789abcdef0123456789abcdef" }, "validationErrors": "null" } } ``` ### 501 Not Implemented **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) ### 500 Internal Server Error **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) ### default The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. The [error reference](https://devportal.demo.winkpg.io/docs/errors.md) lists the values `error.code` can take. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) _Example: Business rule refused the request_ The request was understood and rejected by a platform rule. This is the shape that carries a code from the catalog above, so branch on error.code rather than on the message text. The HTTP status is the one listed against the code. ```json { "error": { "code": "Transactions:OperationNotAllowed", "message": "The operation 'Void' is not allowed on a Sale transaction with result 'Approved' and settlement state 'Settled'.", "details": "null", "data": { "correlationId": "0123456789abcdef0123456789abcdef" }, "validationErrors": "null" } } ``` ### 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. **Content type:** `application/problem+json` Schema: [`RateLimitProblemDetails`](https://devportal.demo.winkpg.io/docs/api/models/RateLimitProblemDetails.md) Properties: - `type` (string) required: The problem type identifier. Always the same value: the failure is the status code itself, so there is no sub-type for a caller to branch on. (nullable) - `title` (string) required: A short, human-readable summary of the problem type. (nullable) - `status` (integer(int32)) required: The HTTP status code, repeated in the body as the problem-details format defines. - `detail` (string) required: A human-readable explanation of this occurrence of the problem. (nullable) - `retryAfterSeconds` (integer(int32)) required: How long to wait before retrying, in whole seconds, carrying the same figure as the `Retry-After` header. Always at least one: a value of zero would invite an immediate retry that is certain to be rejected again. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.demo.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) ## Example request Every block below sends the same request.
