Magento 2 - Request sample for carts/mine (GET)

I try to call the carts/mine GET route of the Magento 2 REST API, but it does not show a request sample in the documentation.

It says "Returns information for the cart for a specified customer."

But how do I specify the customer?

You should include a customer bearer to call this API. You can get it from calling /integration/customer/token. Here is an example:

POST https://<host>/rest/V1/integration/customer/token
Content-Type: application/json

{"username":"<email>", "password":"<password>"}

It will return a customer token looks like this:

"3zznrpsthn6m3dheeacyfe3xzdjryd3y"

Then use this bearer token to call cart/mine API:

GET {{host}}/rest/V1/carts/mine/
Authorization: Bearer 3zznrpsthn6m3dheeacyfe3xzdjryd3y
Content-Type: application/json

And this is an example response:
