Hi I am using paypal sdk. I got stuck and I think there is a problem with paypal. I am trying set a plan in an agreement and I can't move on. Please help. $plan = Plan::get('P-8S006071UD1304535TRTZZNI', $apiContext); $agreement->setPlan($plan); I get this error: Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/billing-agreements/. And when I try with anything like this: $plan = Plan::get('Illputwhatever', $apiContext); $agreement->setPlan($plan); I get this error: Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/billing-plans/Illputwhatever.
