I see at least two mistakes in request, but they aren't related to the error message. According to documention (developer.paypal.com/docs/classic/api/merchant/…) you have to 1) use L_BILLINGTYPEn parameter instead of BILLINGTYP and 2) use PAYMENTREQUEST_n_AMT instead of AMT. I have used SOAP format instead NVP but it seems your request to init billing agreement is incorrect. And yes, your method Sale is correct. – andrykonchin

You are inputting all the parameter and value under Headers.

You should put all the parameters/values under Params, located at the right side the URL endpoint field.
