The Salesforce tool for Superface allows you to quickly add the following capabilities:
You will need a Salesforce account to authenticate with Superface.
You must provide the domain name for your Salesforce instance as well as connecting your personal Salesforce account.
When logged into Salesforce, take a look at the address bar of your browser. The URL should look something like https://superface-dev-ed.develop.lightning.force.com. The domain you need for Superface is everything that comes after https:// and before .lightning.force.com.
In the example above, the domain would be superface-dev-ed.develop.
Next, you need to connect your Salesforce account by clicking Sign in with Salesforce. If you are already signed in you will be redirected to the authentication flow below. If not, you may be asked to log in first.
Check that you are happy with the level of permissions and click on Allow.
If the connection is successful you will be redirected back to the Superface tool hub.
