node.js - Whether or not my PayPal subscription system is working like it's supposed to -

i have integrated paypal subscription system using express checkout offered paypal in node app, because don't want send card details server , , stay pci compliant.

everything in code works , it's supposed to. no errors. however, when log sandbox account, can't see subscription details. transaction details like:

payment initialized , executed. billing plans created , finally, billing agreement completed. also, correct amount of money deducted sandbox balance.

the issue have when portion of code run:

paypal.billingplan.update(billingplan.id, billingplanupdateattributes, (err, updatedplan) => {    if(err) {      console.log(err);    } else { console.log(updatedplan); }}); 

when run in callback after creating plan, displayed (this updatedplan object above):

{ httpstatuscode: 200 } 

essentially, printed status code no other json data. rest of functions call return nice, full json object id's can save things canceling subscriptions in future.

does ready you? paypal api confusing work with, want make sure working it's supposed to.

thanks
