I don’t know if this will fix everything and make your call function, but the value for Sender batch id is empty. Right under the body of your request in the first screenshot you can see an empty input for both " Sender batch id" and “Recipient PayPal iD”. You’ll need to give these keys a value in order to initialize the call. Also, be careful with the empty space after Sender Batch id.
Where can I get this value from? I couldn’t find it in my PayPal developer account.
They are empty because those are the dynamic parameters. Hence why in the JSON, they are in the brackets <>
I am not sure if Iam going down the right path.
I just want the user to provide me their PayPal id I send them money.
