CSM-Amazon Release Notes - 4.0.2026062228.289721

June 23, 2026

Amazon Listing Report Processing

• Improved the listing document download path so compressed Amazon report files can be decompressed before processing.
• Updated report text handling to read UTF-8 content correctly, including listing data with special characters.
• Preserved original row separators when reading tab-delimited report files, helping CSM process complete listing reports consistently.

Suite Engine Platform Dependencies

• Updated CSM for Amazon to use the current Suite Engine platform dependencies for this AppSource release.
  • Aligns the app with Suite Engine Common Base 2.12, Suite Engine API Engine Library 1.21, and Channel Sales Manager Core 4.9.
  • Be sure to reference the CSM Core release notes for platform-level changes included through the CSM Core dependency.

Amazon Signature Security Handling

• Improved internal handling of Amazon signing keys so signature calculations use protected secret values where supported.
• Keeps existing Amazon authentication behavior while reducing exposure of sensitive signing material during processing.

Fixed

Amazon Listing Import From Listing Reports

• Fixed an issue where Amazon listing report files could download successfully but failed to parse into Business Central.
• Corrected handling for GZip-compressed listing reports and UTF-8 byte order marks at the start of Amazon tab-delimited files.
• Improved full report reading so multi-line listing files are captured for processing instead of only a partial response.
