Signature Key



I've recently joined a new payment system and they run via Authorize but I'm having issues when a payment fails.


It's running on MD5 Hash and I need to change/upgrade this but can't seem to sign up or generate a key.


I've tried phoning and the offices are closed during the stated opening hours by the pre recorded message.


Any help would be great, thanks!

If you need to create a sandbox for testing:


Here is the Hash Upgrade Guide.  It depends on which API you are using.
