Inbound API using Apex code

In this tutorial, we will look at creating an endpoint for Inbound Salesforce API using Apex code.

We will stick to a nice and easy simple example. Our endpoint will rely on the account object.

We will have 3 methods associated with @HttpGet, @HttpPost, @HttpDelete

Get method will return 6 accounts

Post method creates a new account with name.

Delete method will delete the individual account based on ID supplied.

@RestResource(urlMapping ='/AccountInfo/*')
Global class AccountInfo {
    @httpget
    global static List<account> GetAccount()
    {
        list<account> a = [select name from account limit 6];
        return a;
    }
    @httppost
    global static string PostNewAccount(string aName)
    {
        account a = new account();
        a.name = aname;
        insert a;
        return a.id;
    }
    
    @httpdelete
    global static void DeleteAccount()
    {
        RestRequest Req = RestContext.request;
        string val = req.requestURI.substring(req.requestURI.lastIndexof('/')+1);
        delete [select id from account where id =: val];
    }
    
    
}
