What location in Cybersource Business Center do I find the MerchantKeyId?

To use the Cybersource REST API for payments, I'm using the cybersource-rest-client NPM package. With test values from Configuration files, everything functions well. To change from those in the sample config file, I was unable to locate the MerchantKeyId for my test account.

Hey,

In Cybersource Business Center, the MerchantKeyId is usually found under Account Management → Transaction Security Keys, once you’re logged in with admin access. If you don’t see it, permissions or environment settings are often the reason. It’s a bit like dealing with hidden mold issues details matter, and local expertise helps spot what’s not obvious. That’s why I appreciate clear, professional guidance, similar to what local specialists share at https://moldremovaltallahassee-fl.com/ when explaining complex remediation steps.
