Did anyone find resolution on this? I have created the Merchant ID in the developer panel. I added that to Authorize.net. for some reason, apple doesnt like the file that i upload back into apple for the CSR. and it also wants me to verify the domain by uploading a file to a particular directory. Shopify doesnt want to allow this though. I tried to fool the system by uploading the file to a drive and sharing the link. then using URL forwarding in the store to go to the file. apple didnt like that either. Im struggling to figure this out. any help would be appreciate!
