Chapter 2. Using tokens for authentication

Procedure

1. Visit the Red Hat Subscription Manager API Tokens page.
2. Click the Generate Token button.

Procedure

1. Set the offline token value. In this example, we set it in plaintext and shorten the token value for clarity:

   # offline_token='eyJhbGciOiJSUzI1NiIsInR5cCIgOiA'

   Copy to Clipboard Toggle word wrap

2. Enter the following command to create a function to easily filter out JSON values.

   # function jsonValue() {
   KEY=$1
   num=$2
   awk -F"[,:}]" '{for(i=1;i<=NF;i++){if($i~/'$KEY'\042/){print $(i+1)}}}' | tr -d '"' | sed -n ${num}p
   }

3. Enter the following command to extract the access_token:

   # curl https://sso.redhat.com/auth/realms/redhat-external/protocol/openid-connect/token -d grant_type=refresh_token -d client_id=rhsm-api -d refresh_token=$offline_token

   The expected output is similar to the following, where access_token is the token used to authorize your account:

4. Enter the following command to set the access_token as an authorization token that can be used to perform the API call.

   # token=`curl https://sso.redhat.com/auth/realms/redhat-external/protocol/openid-connect/token -d grant_type=refresh_token -d client_id=rhsm-api -d refresh_token=$offline_token | jsonValue access_token`
