Remove field from object list in class [closed]

Question

I have list of accounts and want to use them for post request. How can I remove unnecessary fields like id to set that list in setbody? Now I am just using for loop and json serialize.

Some code. So I need remove id and some other fields. Maybe use Map with key?

Http http = new http();
HttpRequest request = new httprequest();
request.setHeader();
for(Account acc: accList){
String body = json.serialize(acc);
request.setbody(body);

}

Upd: AccList is just a list of recently created account records.It’s in trigger so Trigger.new.

Probably the easiest way to do what you want is use getPopulatedFieldsAsMap, then remove any fields you want to block.

Map<String, Object> fields = acc.getPopulatedFieldsAsMap();
fields.remove('Id');
// etc
request.setBody(JSON.serialize(fields));
