OAuth 2.0 authentication can be implemented in various ways, depending on the collection structure and specific requirements. Below are two basic examples of its usage.

​
Collection level



  1. Open the collection settings and navigate to the Auth tab.
  2. Select OAuth 2.0 as the authentication method and set the grant type to Client Credentials. Fill in the necessary fields with the relevant information.
  3. In the Scripts tab, add the following script to the post-response section: 
if(req.getAuthMode() == 'oauth2' && res.body.access_token) {
    bru.setVar('access_token_set_by_collection_script', res.body.access_token);
}
This script assigns the access_token value from the response body to a runtime variable named access_token_set_by_collection_script, making it available for use in all requests within the collection. You can adjust this script to suit your needs.
  1. Return to the Auth tab and click the ‘Get Access Token’ button. You are now free to use the token stored in the access_token_set_by_collection_script runtime variable in your requests as needed.



​
Request level



  1. Create a new empty request and navigate to the Auth tab.
  2. Select Oauth 2.0 as the authentication method and set the grant type to Client Credentials. Fill in the necessary fields with the relevant information.
  3. In the Scripts tab, add the following script to the post-response section: 
bru.setVar('access_token_set_by_request_script', res.body.access_token);
This script assigns the access_token value from the response body to a runtime variable named access_token_set_by_request_script, making it available for use in all requests within the collection. You can adjust this script to suit your needs.
  1. Return to the Auth tab and click the ‘Get Access Token’ button. You are now free to use the token stored in the access_token_set_by_request_script runtime variable in your requests as needed.
