Response 401 when accessing PayPal sandbox Rest API

I was able to request an access token at https://api.sandbox.paypal.com/v1/oauth2/token and send a POST to create a new payment at https://api.sandbox.paypal.com/v1/payments/payment using the given access token. Those two APIs ran without any problem.

But when performing a GET to the payment_id that I created also using above access token, it gave me 401 https://api.sandbox.paypal.com/v1/payments/payment/PAY-XXXX. This is the step where I want to execute the payment at my return_url.

I'm using the PayPal PHP SDK downloaded from https://github.com/paypal/PayPal-PHP-SDK. Everything is still in sandbox mode. The client_id and secret are sandbox credentials.

Also, I have tried running cURL to above payment_id's URL yet it gave HTTP/1.1 401 Unauthorized as well.

curl -v https://api.sandbox.paypal.com/v1/payments/payment/PAY-XXXX 
-H 'Content-Type: application/json' 
-H 'Authorization: Bearer ACCESS_TOKEN'

According to the documentation, 401 means invalid or expired access token but I don't think it applied here because the previous POST command could run successfully.

UPDATE #1: In fact, I have tried running the whole flow (request access_token, post payment, get payment and execute) using cURL and did not have problem. So the problem must be with the PHP code

There was one typo in the PHP which gave me wrong access_token. Interestingly, the POST method to create new payment was still allowed that confused me.
