Correcting error transactions

Our customers often find a need to correct their transaction errors after the fact, especially when the transactions are submitted through extractor applications. ErrorTransactions APIs provide a solution to this problem. These APIs will allow customers to review historical error transactions, fix them, and delete them.

In this release, we’ve added two APIs:

  • FetchErrorTransactions API – to fetch historical extractor-based failure transactions
  • DeleteErrorTransactions API – to delete failure transactions that no longer need be tracked

At the same time, CreateTransaction as well as CreateOrAdjustTransaction APIs are also updated to record extractor-based transaction failures.

Note that these error transaction APIs will only support extractor scenarios from this release; in the future, they’ll be expanded to more scenarios like batches and connectors.

Fixes and improvements

  • Stopped reflecting input in error messages, to prevent security issues
  • Enabled acceptance of multiple TaxCodes in SendSales APIs
  • Added new field isFein to company model to identify whether taxPayIdNumber is a FEIN or SSN
  • Enabled Meals tax calculations
