If you use the AS2 protocol to receive EDI messages from an EDI partner, use the AS2 web app to manage the interaction with the EDI partner.

The AS2 web app runs in the Azure cloud.

When the web server of the EDI partner sends data to the AS2 web app, it:

1. Decompresses the received data, if the received data is compressed.
2. Decrypts the data.
3. Checks the signature.
4. Stores the data in an EDI message file in the general storage location.
5. Sends an MDN reply to the web server of the EDI partner. The MDN reply can be that the data is:
   • Processed successfully.
   • Not processed because something went wrong. For example, the data cannot be decrypted, or the signature is invalid.
