So I am working with the D&B Hoover Direct 2.0 API to try and integrate data from there to Salesforce. I am successfully getting a JSON response that looks as follows:

                }
            ]
        }
    }
}

The problem I am running into is that some of the data I need (org Name, address, revenue etc) have special characters like $ and @ that are reserved in Apex, preventing the de-serialization from working properly when I create a class using https://json2apex.herokuapp.com/ . I cannot create data structures to store these values as Apex will not allow $ and @ in variable names and class names.

If anyone has any ideas or suggestions to create an Apex class to properly handle the deserialization that would be greatly appreciated. I am beginning to think I may have to use the JSON parser method to manually parse the response and create classes/data members accordingly.

From a few minutes of looking, the best option looks like using the JSON2Apex "Create explicit parse code" option as a starting point because that generates code such as this:

if (text == '@CurrencyISOAlpha3Code') {
    @CurrencyISOAlpha3Code = parser.getText();

and it would be pretty simple to knock off the awkward characters from only the variable names:

if (text == '@CurrencyISOAlpha3Code') {
    CurrencyISOAlpha3Code = parser.getText();

Alternatively, for this sort of problem, JSON.deserializeUntyped where the data is pulled into a tree of Map<String, Object> so arbitrary strings can be kept in the keys can be a good way to go, particularly if you only want to extract a few values by pulling those values out using the key value strings.

  • Thanks for the tips, I will try that out now and see if it works! Commented Jul 18, 2018 at 14:43
  • For what it's worth, JSON2Apex hasn't been updated to use a switch, either, which should have considerable performance benefits over the chained-if-else method.

  • @sfdcfox Yeah it's a good example of where switch might help (for large data volumes). Another JSON2Apex tweak would be to automatically sanitise the field names...
