If you use a secure HTTPS AS2 connection, your trading partner may need to update your HTTPS SSL certificate. You must contact your trading partner to determine if they need to update your HTTPS SSL certificate. Updating this certificate allows you to make HTTPS requests to send AS2 messages to the Celigo platform.

Note

Your trading partner is responsible for updating the HTTPS SSL certificate. The process for updating this certificate depends on the AS2 software the trading partner is using. Celigo Support staff will not be able to assist with updating this.

An HTTPS SSL certificate is not the same as an AS2 certificate.

The HTTPS SSL certificate is used to establish an HTTP layer connection to the Celigo platform. This is what expires and must be updated.
The AS2 certificate is used to encrypt/decrypt the AS2 message and verify the signature of the AS2 message. The Create and update self-signed SSL certificates for AS2 connections article explains how to create and update a self-signed X.509 certificate for use in the My AS2 Station Configuration. It does not explain how to update an HTTPS SSL certificate.

Your connection consists of three hierarchical certificates. The expiring certificate is the “SSL Certificate” (see figure).

Your integrations will not be affected by the expiring certificate unless you are using an HTTPS AS2 connection with a system that does not automatically populate the new certificate.

For customers affected by the changes, ask your trading partners to download the new HTTPS SSL certificate and update your system manually.
