Creating a custom badge for your OAuth App

You can replace the default badge on your OAuth App by uploading your own logo image and customizing the background.

By default, a new OAuth App will have an automatically generated identicon. An identicon badge looks something like this:

After you create an OAuth App, you can customize the app's badge by uploading a logo and selecting a background color. A badge is a square logo image inside of a circular badge. You can choose a background color for the badge, which can be used to visually distinguish your app.

Your logo should be a PNG, JPG, or GIF file under 1 MB in size. For the best quality rendering, we recommend an image size of at least 200px x 200px.
