Batch Processing
This section contains information about batch processing procedures and the required variables for each response file. Use this integration method to process large numbers of transactions in a batch across multiple accounts by specifying the source key for each transaction in the request.

Conventions

x = Incrementing Sequence Number
  • Numbers can be skipped, but they must always be greater than the previous file.
  • Files with older or invalid sequence numbers are ignored.
  • Sequence Number Max Value = 999999999 (9 digits)
KVP = URL Encoded Key-Value-Pair
  • Sample: xName=John%20Smith&xAmount=1
  • Note: Ensure that all values are URL encoded.

Batch Upload Lifecycle

Request

  1. 1.
    Client uploads Request/REQUEST_X.KVP
  2. 2.
    Client uploads Request/PROCESS_X.KVP
  3. 3.
    Batch process is triggered when Request/PROCESS_X.KVP is received

Response

  1. 1.
    Gateway saves Response/RESPONSE_X.KVP
  2. 2.
    Gateway saves Response/COMPLETE_X.KVP
  3. 3.
    Client polls and parses Response/COMPLETE_X.KVP
  4. 4.
    If xStatus=Success then Client downloads and parses Response/RESPONSE_X.KVP
  5. 5.
    Client deletes all files from Response folder
