Hello, I've followed instructions to setup paypal marketplace demo as local installation. 1) onboarding (v1/customer/partner-referrals) fails with "{"name":"AUTHORIZATION_ERROR","message":"Caller is not authorized to access this resource","debug_id":"1a5ef7ba8184"}" 2) checkout fails with "This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow." In logs I see that "v1/oauth2/token" call return "access_token", I assume everything is ok with the credentials I use. Because invalid credentials issue ""{"error":"invalid_client","error_description":"Client Authentication failed"}"" So the question: is paypal for marketplace limited access API, i.e. not available with sandbox at all or need explicit approval from paypal side? Or I've missed some configuration steps? Thank you, Sergey Boyko
