# Validation

### Receipt File

The importer generates a receipt file in the import directory when you upload a new card-linked transaction file. The receipt file contains the import's reference id (Trace ID).

File name: `receipt_{originalFileName}.txt`

### Summary File

The summary file contains the status of the import. The importer generates a new summary file for each card-linked transaction file you upload.

File name: `{originalFileName}_summary.json`
