Yammer REST API: How to get access tokens for external networks?

You need to hit https://www.yammer.com/api/v1/oauth/tokens.json. This topic is covered over on the Zapier blog. Their blog specifies an access_token as a query string parameter, but that is no longer supported. Specify the access token for the current user on the Authorization header as shown on the Yammer developer site.
