Creating a 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!




You go to your merchant interface and go to API credentials. Select the option to generate a new signature key.  It sounds like you are using SIM or DPM, which means the next step will be to update your MD5 hash function to a sha512 hash function.  You will need to update the server side code. Confirm what integration method you use before getting too deep into this. You use a different string to calculate the hash depending on what method you are using.
