I am able to grant the permissions of the 3rd party access token, but I can't have access to the transactions history. I receive a message saying that "I am not authorized to perform 3rd party calls for this API. You need to be part of the Partner Program for the same." The thing is, I have already a Partner account and I am using it. So someone knows what could be the problem? Paypal support doesn't help.
So, I think this would be one of two things. Either the permission isn't being granted in live for Transaction History, or your account doesn't have the Partner Permissions to be able to access someone's transaction history. If you're sure the Transaction Search/History permission is being granted, then it just might require that scope addition for your partner account
If you were contacted by the partner team during the partner approval process, then you should be able to reach back out to them via email and inquire if you also have approval to have the Transaction History Partner Permission enabled. If you aren't able to reach out to them via email, then you might have to go through normal support channels asking for this change to your partner permissions.
If you don't have the partner team email address, then you would have to go through our customer support team, asking them for help on getting this added. You can do so by clicking the "Help and Contact" link at the bottom of this page and then click on "Message Center". From there, send us a message explaining the need and you should have no issues getting information or help with your account.
