String responsebody=`'{"http_status_code":"200","response":{"InstantIDResponseEx":{"response":{"Result":{"InputEcho":{"SSN":"false","Name":{"First":"0","Last":"false"},"Address":{"Zip5":"false"},"HomePhone":"false"},"UniqueId":"false","VerifiedInput":{"Name":{"First":"false","Middle":"false","Last":"false"},"Address":{"StreetAddress1":"false","City":"false","State":"false","Zip5":"false","Zip4":"false"},"SSN":"false","HomePhone":"false","DOB":{"Year":"false","Month":"false","Day":"false"}},"DOBVerified":"false","NameAddressSSNSummary":"false","NameAddressPhone":{"Summary":"false"},"ComprehensiveVerification":{"ComprehensiveVerificationIndex":"false"},"AdditionalScore1":"false","AdditionalScore2":"false","SSNFoundForLexID":"false","AddressPOBox":"false","AddressCMRA":"false","InstantIDVersion":"false","EmergingId":"false","AddressStandardized":"false","StandardizedInputAddress":{"City":"false","State":"false","Zip5":"false","Zip4":"false"},"BureauDeleted":"false","ITINExpired":"false","IsPhoneCurrent":"false"},"Header":{"Status":0,"TransactionId":"false"},"Pdf":"abc"},"_xmlns":"200"}}}';`

APIResponse layer=new APIResponse ();

APIResponse data=layer.parse(responsebody);

I am getting null whenever I am trying to desearlize the response. Also I'm not able to access value of pdf variable. Please advise.

  • if it's null, why are you expecting to be able to access pdf? What's null exactly? your data variable? Please edit your question to be more specific about what you are seeing, because you can't be getting null.

The reason this isn't working is because your responsebody doesn't match up with your class.

Your responsebody has an extra layer to it. It has 2 properties:

  • http_status_code
  • response

Your class doesn't have these.

Either update your class to match your json, or change your json to:

  • I tried below code APIResponse ap=new APIResponse(); APIResponse resp=ap.parse(res2.getbody()); //giving my response values. Can you please tell me how can get PDF vaule which is string value. from this wrapper class. Below code APIResponse.cls_response =resp.cls_response; givine not exist Commented Sep 20, 2023 at 3:03
  • Does this answer your actual question of why you're getting null? if so, mark it as correct answer. You might also want to look at: salesforce.stackexchange.com/questions/57459/…
