I'm new to Apex REST/SOAP web services world and I'm struggling with a project of integration. What I have a API documentation from client which contains cURL examples, fields and sample JSON response. My questions,
How should I start and how can I call this API data inside Salesforce? I need ability to pull and push the data into Salesforce.
Are there any changes that need to do in external API system or can I call web services directly in Salesforce if I have login ID and Password of API?
In integration projects like this, what should be first step? What information will I need from client to start the integration?
I have read few articles online on REST but none of the article provide real time examples. Can you Apex Gurus please help? Any help is much appreciated.
