Version 1.2

Deployed September 15, 2026

Changes

Added percents-txn-stream uploads in CSV and JSON.
Upload responses now include a file ID and an expiry time.
Added file history and status endpoints with validation and processing results, received dates, and processing completion dates.
Added signed FileUploadProcessingResult webhooks with processing counts and error details. These results are separate from approval of individual transactions.
Duplicate filenames for the same issuer now return 409, including when the previous upload failed.
Native and Plaid files are automatically validated before processing in production. Sandbox uploads are validated without production ingestion.
API tokens, client certificates, and webhook signing keys now belong to entities. File access remains tied to the associated issuer.
CSV remains the default when fileType is omitted. Plaid uploads require fileType=json.
Native transaction rows may include an optional four-digit mcc, which is saved with the transaction.
