When i first time trying to access to Magento 2 API using CLI curl command. I couldn’t find any good reference or example. So i have decided to write my own reference for future.

You can access Magento 2 API in two simple steps. Unlike from Magento 1 you don’t have to generate separate API credential you can store admin credentials to access.

Step 1: Generate Token

curl -X POST "http://magento2.test/rest/V1/integration/admin/token" \
     -H "Content-Type:application/json" \
     -d "{  \"username\":\"adminUsername\", \"password\":\"accountPassword\"} "

Expected output is a random string like this. Its your session token and will be used in further access

"gow7n7etw5lckj6hvc20ngs32z949w11"

Step 2: Access customer information
Using the same token in header that we received in earlier API call

curl -X GET "http://magento2.test/rest/V1/products/1" \
 -H "Authorization: Bearer gow7n7etw5lckj6hvc20ngs32z949w11"

Expected output will be the customer information in JSON format.
