  1. Click the Copy to Clipboard button located directly beneath the code sample
  2. In Postman, click Import to display the Import dialog box.
  3. In the Import dialog box, click Paste Raw Text, and then paste in the copied code. The Import dialog box should look similar to this:

  4. Click Import, and the Curl command will be converted to a format that can be run from within Postman. All you need to do now is configure the command to work with your Janrain implementation.
