Please find the link to download the working code. client id, oAuth token of verified admin of your network needs to be updated along with the user email id and the group id to which the user has to be added.
Step 1: https://www.yammer.com/api/v1/users/by_email.json?email={0} - returns user id from the user id. If you have user id handy you can ignore this step.
Step 2: https://www.yammer.com/api/v1/oauth/tokens.json?consumer_key={0}&user_id={1} - Impersonate the user and get the oAuth token after impersonation. Below diagram explains the request flow.
Note: Above diagram is taken from the book - Develop on Yammer: Social Integration for Modern Business Applications - By Pathik Rawal, Pryank Rohilla
Step 3: https://www.yammer.com/api/v1/group_memberships.json?group_id={0} - Make a post call to add the user to the group with the impersonated token as Authentication - Bearer token.
Step 4: https://www.yammer.com/api/v1/group_memberships.json?group_id={0}&user_id={1}&approve=1 - Make a post call with the group admin - oAuth token to approve the request.
Step 4 is not documented in Yammer API but it works. At any point of time, it can go unsupported.
