Web services can have several types of authentication. With Basic, just the username a few password are sent with the request. When you use that in an integration, you will typically need to use the variables in the headers, but you enter them secretly in the integration. With OAuth, your integration will usually sent the client and secret and get back a token you then use in the request or header. The other type may be API key which is Custom and allows you to store the key secretly in the integration and use a variable in the data action. I hope this helps. Ask you web developers what is needed.
