Here is a sample script that calls the messages.json endpoint and dumps its response: its response: To make API calls in PowerShell, the Invoke-RestMethod cmdlet documented at will be used. This header looks like “Authorization: Bearer OAUTH_TOKEN” in plain text, but an example of passing this in PowerShell can be found below.

Once you have obtained this OAuth token, you need to pass it to the API in a header. It will be used it to authorize your API calls and won’t expire until something is explicitly done to revoke it.Īpp Registration Example Obtaining an OAuth Token Example Once the app is registered, click “Generate a developer token for this application” and save this OAuth token. If you are unsure what to put as the Website and Redirect URI, just put an address to your company’s website for the time being. To obtain this OAuth token, first register an app in Yammer, detailed at. To authorize an API call, an authorization header with the OAuth token is sent stating who is making the call. Each endpoint’s documentation will describe the data it can consume when generating its output.Įvery API call must be authorized before it will return data. Any data passed to that API endpoint – For example a user id or a page number.It tells the API who is making the call and that you’re authorized to make those calls. The authorization headers – This is akin to logging into the API.A list of our supported API endpoints, their URLs and the input they take can be found at. With this article, I hope to demystify APIs and illustrate how anyone can utilize them to perform tasks like obtaining, posting, and deleting messages. If you’ve never worked with an API before, this can seem like a daunting task. While most day to day tasks can be accomplished in the Yammer web app, utilizing our APIs can open up administrative and automation options previously very time consuming.
