This is unresolved, and I'm facing the same issue. The original post mentions that they're using the PayPal Smart Buttons solution to create the subscription. The same problem is happening in my project, a javascript console error `POST https://www.sandbox.paypal.com/v1/billing/subscriptions 404 (Not Found)` For reference my code is the same as the documentation but with the plan_id I generated substituted in (note, this isn't my actual plan_id): paypal.Buttons({
createSubscription: function(data, actions) {
return actions.subscription.create({
'plan_id': 'P-75432334R0481662WL7ZER6A'
});
}
}).render('#paypal-button-container'); Edit: Furthermore the link provided in the console error ( https://developer.paypal.com/docs/api/v1/billing/subscriptions#RESOURCE_NOT_FOUND ) redirects to an unhelpful page, I believe the relevant info is at https://developer.paypal.com/docs/subscriptions/troubleshoot/ , although this info didn't help me address the problem anyway.
