Hi, I have add pay pal subscription button in my website. I need to fetch the list of transaction by subscription id . When I call https://api.paypal.com/v1/billing/subscriptions/I-XJ3D0WFESK0V/transactions?start_time=2020-11-01T07:50:20.940Z&end_time=2020-12-31T07:50:20.940Z'); everething is well, I get the list of transactions. Now I put $subscriptionid = 'I-XJ3D0WFESK0V'; and call https://api.paypal.com/v1/billing/subscriptions/{$subscriptionid}/transactions?start_time=2020-11-01T07:50:20.940Z&end_time=2020-12-31T07:50:20.940Z'); it says invalid request {"name":"INVALID_REQUEST","message":"Request is not well-formed, syntactically incorrect, or violates schema.","debug_id":"51282f2c099ec","details":[{"field":"subscription_id","value":"{$subs}","location":"path","issue":"INVALID_PARAMETER_SYNTAX","description":"The value of a field does not conform to the expected format."}],"links":[{"href":"https://developer.paypal.com/docs/api/v1/billing/subscriptions#INVALID_REQUEST","rel":"information_link","method":"GET"}]} Please tell what is the way to get the transaction list using variable subscription id?
