Live paypal acceptance of payment not working

[micontenido]

Hello Paypal Support Team

I have integrated the REST API for accepting payments on my website.

I have tested the payments in the sandbox mode and they are working fine.

Now I am trying to test the payments in live mode, which is not working. Every time got the error of seller account is not configured. For reference please see the screenshots.

Let me know If I have to do some settings in my account.

It would be helpful, if you guys guide me through the settings (if necessary) to do in my account.

Thanks
