The API key is a unique encrypted string assigned by Soffront which identifies the user making an API call. This replaces basic username/password authentication. Once you have signed up for a Soffront account, you can get an API key by performing the following steps:
1) Navigate to the top right-hand side of your Soffront Home screen and click on the Settings icon
2) Then go to the left-hand side and click on the API Key option under the Integration section
3) It will show you the confirmation dialog box below
4) Click on the API KEY button to generate an alphanumeric API key, which you can copy and use to make API calls.
