Hi dev folks, I’m a new to Salesforce integration. I need some guidance on how to perform integrations with third party systems using Salesforce and to also know the different methods of integrations. I know the basics of integration.
 
The problem that I face now is that say if I wanted to connect LinkedIn with Salesforce. I look through the API guide of LinkedIn, then I try it in postman. Then, I try to make the callout using apex. But sometimes I struggle when there is authentication and I don't know how to authenticate and fetch the data.
 
The reason why I need to get familiar with integration is because my project uses a lot of integration and sometimes I don't understand what they are talking about. For example, recently there was a conversation about JWT, inbound and outbound integration etc. which I have no idea about.
 
I would appreciate if you can give me an overview or guidance as to where I should start and then move on to advanced concepts. It would also be great if you could list down the steps that I need to understand before I start with integrating with external systems. Also, I would really appreciate if you could provide me hands on exercise to practise and sharpen my skills.
