Salesforce Integration Interview Questions check how you connect Salesforce with other systems, and how much code-level knowledge you have as an admin. This is Part 13 of our 25-part series.<\/p>\n\n\n\n

In Part 8<\/a>, we touched on APIs. Here we go deeper into authentication, events, middleware and the basic SOQL and Apex that admins are now often asked about. Our External Client Apps guide<\/a> is a good start.<\/p>\n\n\n\n

How to Use These Salesforce Integration Interview Questions<\/h2>\n\n\n\n

You do not need to code to answer most of these. First, learn the words: API, OAuth, integration user, event and middleware. Next, learn what admins set up versus what developers build. Then practise the scenarios, naming the tool and the security step in every answer.<\/p>\n\n\n\n
