Swell uses token authentication to control access to the API.
Using Token Authentication
In order to connect to Swell, you'll need to provide your Store ID and Secret API Key. To do so, navigate to 'Admin' > 'Settings' > 'API'. At the top of the page, note your Store ID value. Under one of the secret keys, click on the eye icon to make the secret key visible. To establish a connection, set the APIKey to your Swell Secret API Key and your StoreId in the ProfileSettings connection property.
