I'm kind of new to REST API and I have to map an endpoint that returns me this JSON:
{"request": {"Target": "Affiliate_Offer","Format": "json","Service": "HasOffers","Version": "2","api_key": "3225235c5633454cf60d35838cf8466f8fcf184b1360d","Method": "findAll","contain": ["Country" ]},"response": {"status": 1,"httpStatus": 200,"data": {"18292": {"Offer": {"id": "18292","name": "247 Profit Formula","description": "<b>Description:</b> Register for a chance to earn $500 or more per day from home!<br><br>\r\n\r\n<b>Requirement:</b> First Page Submit<br><br>\r\n\r\n<b>Country(ies):</b> US<br><br>\r\n\r\n<b>Media:</b> Blog, Display, Newsletter, Social Media, Text Links<br><br>\r\n\r\n<b>Restrictions:</b> No Incentives; no Email<br><br>\r\n\r\n<b>Other:</b> None.<br><br>\r\n","require_approval": "0","require_terms_and_conditions": 0,"terms_and_conditions": null,"preview_url": "https://www.247profitsecret.com/formula?","currency": null,"default_payout": "0.90000","protocol": "server","status": "active","expiration_date": "2039-01-06 04:59:59","payout_type": "cpa_flat","percent_payout": null,"featured": null,"conversion_cap": "0","monthly_conversion_cap": "0","payout_cap": "0.00","monthly_payout_cap": "0.00","allow_multiple_conversions": "0","allow_website_links": "0","allow_direct_links": "0","show_custom_variables": "0","session_hours": "24","show_mail_list": "0","dne_list_id": "0","email_instructions": "0","email_instructions_from": "Your List Name","email_instructions_subject": "Survey Takers Needed\r\nFortune 500 Companies Need You!\r\nEarn $45 Per Online Survey\r\nSimple Survey Jobs","enforce_secure_tracking_link": "1","has_goals_enabled": "0","default_goal_name": "","modified": 1634138487,"use_target_rules": "0","use_payout_groups": "0","link_platform": null,"is_expired": "0","dne_download_url": null,"dne_unsubscribe_url": null,"dne_third_party_list": false,"approval_status": "approved" },"Country": {"US": {"id": "840","code": "US","name": "United States","regions": [] } } },"17823": {"Offer": {"id": "17823","name": "American Career Guide","description": "<b>Description:</b> American Career Guide is your free guide to help you search jobs in your city!<br><br>\r\n\r\n<b>Requirement:</b> Email Submit<br><br>\r\n\r\n<b>Country(ies):</b> US<br><br>\r\n\r\n<b>Media:</b> Display, Email, Newsletter, Search, Text Link<br><br>\r\n\r\n<b>Restrictions:</b> 18+; no Incentives, no Social Media<br><br>\r\n\r\n<b>Other:</b> Contact Affiliate Manager for Suppression list. <br><br>\r\n","require_approval": "1","require_terms_and_conditions": 0,"terms_and_conditions": null,"preview_url": "https://jobs.theamericancareerguide.com/api/offer","currency": null,"default_payout": "2.40000","protocol": "server","status": "active","expiration_date": "2030-01-08 04:59:59","payout_type": "cpa_flat","percent_payout": null,"featured": null,"conversion_cap": "200","monthly_conversion_cap": "0","payout_cap": "0.00","monthly_payout_cap": "0.00","allow_multiple_conversions": "0","allow_website_links": "0","allow_direct_links": "0","show_custom_variables": "1","session_hours": "24","show_mail_list": "0","dne_list_id": "0","email_instructions": "1","email_instructions_from": "AmericanCareerGuide\r\nAmerican_Career_Guide\r\nTheAmericanCareerGuide\r\nJobsAvailable","email_instructions_subject": "Job Offers Are Waiting For You\r\nJobs Available - Positions Paying Up to $35/Hour\r\nHelp Wanted - Jobs Available in Your Area!\r\nHelp Wanted in Your Area - Pick Your New Job Today!\r\nLooking for a New Career?

@GetMapping("/find-all-offers-api")public ResponseEntity<OfferMapper> findAllOffersApi() { log.info("Find All Offers From Api - Controller Call"); return service.findAllOffersApi();}My service implementation:
@Overridepublic ResponseEntity<OfferMapper> findAllOffersApi() { log.info("Find All Offers From Api - Service Call"); HttpHeaders headers = new HttpHeaders(); headers.setAccept(List.of(MediaType.APPLICATION_JSON)); HttpEntity<String> entity = new HttpEntity<>("parameters", headers); return restTemplate.exchange(GET_ALL_OFFERS_API, HttpMethod.GET, entity, OfferMapper.class);}Now I'm getting a little bit confused. I created the OfferMapper to receive all the attributes from this JSON but some properties are coming null also I don't know if creating sub-objects (OfferRequest request, OfferResponse response) is the correct way to map it.
@Data@AllArgsConstructor@NoArgsConstructor@JsonIgnoreProperties(ignoreUnknown = true)public class OfferMapper { OfferRequest request; OfferResponse response;}Here is the OfferResponse request and response:
@Data@NoArgsConstructor@AllArgsConstructor@JsonIgnoreProperties(ignoreUnknown = true)public class OfferRequest { private String target; private String format; private String service; private String version; private String api_key; private String method; private List<String> contains;}@Data@NoArgsConstructor@AllArgsConstructor@JsonIgnoreProperties(ignoreUnknown = true)public class OfferResponse { private int status; private int httpStatus; private OfferData data;}When I call with postman I get this response:
{"request": {"target": null,"format": null,"service": null,"version": null,"api_key": "3225235c5633454cf60d35838cf8466f8fcf184b1360d","method": null,"contains": null},"response": {"status": 1,"httpStatus": 200,"data": {"offer": null }}}
The call return some values but I don't understand why Im getting those nulls values and also how I'm gonna make this part in Java because its not like a list structure the JSON does not have [] for the offers only {}:
"data": {"18292": {"Offer": {"id": "18292","name": "247 Profit Formula",
