New features and enhancements

The April 2025 release of B2B Gateway includes the following new features and enhancements.

REST API to reprocess multiple file-level events

You can reprocess multiple file-level events using the new reprocess event REST API and generate new reprocessed events from the existing events.
To reprocess one or more events, use a POST request with the following URL:
https://b2bgateway.<pod>.<baseUrl>/b2b-gw/api/v1/event/reprocess
In the request body, you can use a ',' comma separator to provide a list of event IDs that need to be reprocessed.

Run Partner REST API enhancements

You can include the advanced session properties of a mapping task in the Run Partner API that you use to run partner flows. Use the mctAdvSessionProperties object to define key-value pairs of advanced session properties.
For example, you can configure the amount of buffer memory that is used to move a block of data from the source to the target in the advanced session properties.
For more information, see B2B Gateway.
