Payment Files API

Payment files API

Payment files contain transactions that you want QuickStream to process. Payment files contain capture and refund transactions in payment batches. Each payment batch contains transactions for either credit card or bank account transactions but not both. Use this resource to:

  1. Upload a payment file.
  2. Get the status and details of a payment file.
  3. List payment files uploaded in the last 365 days.
  4. Get the details of a payment batch.
  5. List the payment batches in the payment file.
  6. List individual transactions contained in each payment batch.

To use this feature:

  1. Generate a file in one of the Payment File Formats.
  2. Upload the file.
  3. Get the status of the file.
  4. If QUEUED, Queued for processing. Wait a minute and then get the status of the file again.
  5. If ERROR, correct the errors and upload the file again.
  6. If PROCESSING, QuickStream is checking the file for format errors and processing transactions in the file. Payment files with a very large number of transactions may take some time.
  7. If AWAITING_CLEARANCE, QuickStream is waiting on all transactions to clear with the other financial institution. Bank account payments may take up to 5 business days to clear.
  8. If COMPLETE, update your system with the status of individual Payment Batches and Transactions.

Upload payment file

To upload a payment file, you must:

  • Create a file in one of the Payment File Formats.
  • Encode your POST as multipart/form-data using curl or a standard library.
  • In the multipart request:
    • send a field named file containing a file with a unique filename, and
    • send a field named format with CSV, CSV_TOKENS, FLAT_FILE, FLAT_FILE_TOKENS, MTS or MTS_TOKENS matching the chosen Payment File Format.

Request

POST /payment-files

Use your Secret API key to access this resource.

Request headers

Header Description
Prevent-CSRF Set to true. Required. This header is required for multipart requests to prevent Cross-Site Request Forgery

Request body

Encode your POST as multipart/form-data. Provide the file contents in the multipart binary part. Provide the following in the multipart request part:

Field Format Description
file string File with a unique file name.
format string The format of the file. Provide CSV, CSV_TOKENS, FLAT_FILE, FLAT_FILE_TOKENS, MTS or MTS_TOKENS matching the chosen Payment File Format.
ignoreDuplicateCheck boolean Optional. If true, the duplicate check will not be performed. You must still update the Unique File Identifier and Unique Batch Code in the Flat File, or the Creation Date and Creation Sequence in the MTS orders file to unique values if you have already processed a payment file with these values. Defaults to false when not provided.

Response

If successful, this method returns the Payment File Model in the response body. The Location response header contains the URL to the payment file you uploaded. The status field describes the status of the payment file.

HTTP status codes

See HTTP Status Codes for more.

Status Code Description More information
201 CREATED The file is stored. QuickStream will check the format of the file and then process transactions. You must check the status of the file.
400 BAD REQUEST Prevent-CSRF header is missing or is not set to true.
422 UNPROCESSABLE ENTITY The request contained invalid data or the server has detected a duplicate payment file. Refer to errors in the response body for more. View more

Duplicate checking

This API returns a 422 UNPROCESSABLE ENTITY when it detects a duplicate payment file. A payment file with the same name and hashed message contents indicates a duplicate.

QuickStream compares payment files over the last 365 days. Bypass duplicate checking by providing ignoreDuplicateCheck = true.

You may further prevent duplicate processing by setting a unique value for the Idempotency-Key header on POST requests.

Payment file formats

Payment files contain payments that you want QuickStream to process. You can process payments by sending a file in one of these formats:

Flat file

Fixed Width Card Payments Bank Account Payments Account Tokens Supported

The Flat File format is a fixed-width text file. The file consists of five record types.

All files are plain text using UTF-8 character encoding. All records are separated by the CR LF end-of-line marker. Each record in the file is 250 characters long.

To upload a payment file in this format you must:

  • Send the parameter format with FLAT_FILE or FLAT_FILE_TOKENS.
  • Use only one supplier business code per batch header.
  • In the Account Number field, use only all card PANs or bank account numbers for FLAT_FILE or all account tokens for FLAT_FILE_TOKENS file.

The payment file has the following general structure:

Data types are listed as:

  • N - numeric 0-9 only.
  • A - letters from the English alphabet, including spaces.
  • AN - letters or numbers (alphanumeric), spaces, underscores _ and hyphens -.
  • S - spaces only

Unless otherwise noted, N numeric fields are right-justified and padded with leading zeros. A letters and AN alphanumeric fields are left-justified and padded with trailing spaces. Amounts are always expressed in cents, e.g. $125.94 is expressed as 0000012594 (assuming the field has a length of 10).

The flat file contains the list of all transactions that were approved and declined during processing. The Flat File format is a fixed-width text file. The file consists of five record types.

  • S - spaces only

Unless otherwise noted, N numeric fields are right-justified and padded with leading zeros. A letters and AN alphanumeric fields are left-justified and padded with trailing spaces.
