I've been trying to create a subscription product for a button on my webpage but have run into some errors that I can't seem to find answers for on Google.

What I have tried:

I retrieved an access token using this command from this page

curl -v https://api.sandbox.paypal.com/v1/oauth2/token -H "Accept: application/json" -H "Accept-Language: en_US" -u "client_id:secret" -d "grant_type=client_credentials"

(I removed the slashes “\” at the line endings and moved everything to one line because the command prompt didn’t seem to run them correctly. I also replaced “client_id” with my app id and “secret” with my app secret leaving the colon between them).

That gave me this:

{"scope":"https://uri.paypal.com/services/invoicing https://uri.paypal.com/services/disputes/read-buyer https://uri.paypal.com/services/payments/realtimepayment https://uri.paypal.com/services/disputes/update-seller https://uri.paypal.com/services/payments/payment/authcapture openid https://uri.paypal.com/services/disputes/read-seller https://uri.paypal.com/services/payments/refund https://api.paypal.com/v1/vault/credit-card https://api.paypal.com/v1/payments/.* https://uri.paypal.com/payments/payouts https://api.paypal.com/v1/vault/credit-card/.* https://uri.paypal.com/services/subscriptions https://uri.paypal.com/services/applications/webhooks","access_token":"A21AAFhs-YZory3SFkTsoj_oHmJ9ix5oVWdrclEJ7Xtqvt15A6LlbRPZhBS391z6Jzs3Kb30aYzaHbbNF9XPEjTPCCWoDokBA","token_type":"Bearer","app_id":"removed","expires_in":32400,"nonce":"2019-12-27T00:35:26ZvOsLgtjrs2Sx7Gz1rUyiAQuvJwLKSPvEZbZP2_Ud0MQ"}

I use the generated access token in the next command.

Then I tried to use the command from this page:

curl -v -X POST https://api.sandbox.paypal.com/v1/catalogs/products -H "Content-Type: application/json" -H "Authorization: Bearer A21AAFhs-YZory3SFkTsoj_oHmJ9ix5oVWdrclEJ7Xtqvt15A6LlbRPZhBS391z6Jzs3Kb30aYzaHbbNF9XPEjTPCCWoDokBA" -d '{"name":"Video Streaming Service","description": "Video streaming service","type": "SERVICE","category": "SOFTWARE","image_url": "https://example.com/streaming.jpg","home_url": "https://example.com/home"}'

Which gave me this:

{"name":"INVALID_REQUEST","message":"Request is not well-formed, syntactically incorrect, or violates schema.","debug_id":"da8f20e6f976e","details":[{"location":"body","issue":"Unexpected character (''' (code 39)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') line: 1, column: 2"}],"links":[]}

So then I tried removing the “Bearer” part of the access token (I thought it might be throwing off the syntax checker or something). That gave me this:

{"name":"AUTHENTICATION_FAILURE","message":"Authentication failed due to invalid authentication credentials or a missing Authorization header.","links":[{"href":"https://developer.paypal.com/docs/api/overview/#error","rel":"information_link"}]}

So I’m kind of at a loss here. Maybe I need to look into the forward slashes not working properly? Or is there some blatant error I’m making that I’m unaware of?

Thank you for any assistance you can provide.
