Yammer for authentication just like facebook -

we creating web application can accessed people have yammer account. have done before facebook, google etc, not #yammer. tired creating external network not useful. please let me know if possible @ all.

first you'll need yammer network , create app in it, can use api. follow these steps. you'll need use oauth2 protocol set yammer authentication piece. means yammer login , home networks have run 3rd party apps enabled able login. if home networks not have 3rd party apps enabled, users not able login.

for simplicity, recommend use sign in yammer button code https://developer.yammer.com/v1.0/docs/authentication can create experience using server side or client side flow, documented here , sdks.

note have network able use app, once finished coding it, you'll need apply have globalized yammer (and potentially list in app directory).
