Merchant Services API False 401 Status

I am currently struggling with the Merchant Services portion of SKY API due to the fact that I keep getting a 401 error even after having correct permissions in an organization that the app is connected to. This app has full read and write permissions everywhere (for testing) and my user (the one attached to the subscription key and authorization of the app) has full admin access to Merchant Services in that org's database. I have tested my creds and was able to successfully pull data from multiple spots within the Raiser's Edge API within their database just not Merchant Services…

If anyone has experienced similar or just happens to know a fix, please let me know.


EDIT: Learned it may not be a false flag as I was informed that there is a separate permission needed for the Payments API. This is now also admin role and will wait until it fully syncs in order to make sure this fixes it or not. If anyone wants the exact error: ```Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription.```

EDIT 2: A decent bit of time has now passed by with the admin center showing all up to date permissions but am continuing to get these 401 flags for an invalid subscription key. Again, I can still pull all other data I need from other calls, but I cannot interface with the Payments API under Merchant Services to get those last pieces.
