I'm super new to Salesforce but need to integrate it into a web app. Basically, we need to figure out how to use the API for four things.
- Query Salesforce and verify a user exists
- Update that users record if it exists
- Return info about that user (order number, address, product ordered, etc)
- Several pages later, update the user again.
I don't know enough about Salesforce yet to figure out this integration, but where can I look for the right information? Or are there any established methods for doing this
