# POST /api/transactions/batch-file/upload Uploads a CSV batch file for transaction processing. The file must be CSV format and no larger than 10 MB. On upload the file is parsed and validated, and its lines are stored; the file itself is not kept. Card numbers are stored encrypted and returned masked. The returned DTO indicates whether validation succeeded (status = Ready) or failed (status = Failed with error details in `ErrorMessage`). **Operation ID:** `batchFileUploadBatchFile` ## Authorization Requires: Transactions.BatchFiles.Upload, merchant scope.

Not an error: the request was answered, and the answer is on the transaction. responseData.declineReasonCode says which of two shapes it took, using the published decline reason vocabulary (/docs/decline-reason-codes on the developer portal): CV_REJECTED when the processor approved and the platform then released the hold with a reversal or void, and CV_NATIVE_DECLINE when the processor applied the rule itself and declined outright, so no hold was ever placed. - `Undefined`: Indicates an undefined or unspecified result. - `resultMessage` (string): Gets or sets a message describing the outcome of the batch file transaction.

(nullable) - `errorMessage` (string): Gets or sets a human-readable description of the error associated with the batch file transaction, if any. (nullable) - `expirationDate` (string(date-time)): Gets or sets the expiration date of the card as supplied in the batch file row. (nullable) - `notes` (string): Gets or sets optional notes associated with the batch file. (nullable) - `errorMessage` (string): Gets or sets a human-readable description of the error associated with the batch file, if any. (nullable) - `concurrencyStamp` (string): Gets or sets a value used to detect concurrent updates to the batch file. (nullable) - `progressPercentage` (number(double)): Calculated property for progress percentage (read only) - `successRate` (number(double)): Calculated property for success rate (read only) ### 400 File is not CSV, exceeds 10 MB, or the merchant does not exist. **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 failed validation_ One or more fields were rejected before any rule ran. error.code is null on the envelope and the causes are in validationErrors, one entry per failure. 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" ] } ] } } ``` ### 403 The caller lacks the upload permission, or the merchant is outside the caller's scope. Nothing is stored. **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)) ### 401 Unauthorized **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)) ### 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. A sandbox request whose merchant has spent the plan's transaction allowance is refused with a different `application/json` body: `code` is `USAGE_BUDGET_EXCEEDED`, and `limit` and `used` report the allowance. `Retry-After` is sent only when the allowance resets. An allowance that never resets sends none, and retrying won't help. **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 type: `object` ## Example request Every block below sends the same request.
