Error and warning codes are numeric and are published as a machine-readable registry at https://adfapi.rightmove.co.uk/v1/property/errorcodes, but that endpoint sits behind the same mutual-TLS gate as the rest of the feed and returns HTTP 403 to anonymous callers (probed 2026-07-26), so the code list itself CANNOT be harvested without a Rightmove-issued client certificate. The envelope below is documented in the public specification and is recorded verbatim; no codes are invented here. response_kinds: - kind: Success description: The call has been successful. - kind: Warning description: >- The call has been successful, but one of the business rules has failed, generating a warning message. Warnings cover both technical and business-rule conditions (for example a Premium Listing product partially applied). - kind: Error description: The call has not been successful due to an error. envelope: common_fields: [Request_ID, Message, Success, Request_Timestamp, Response_Timestamp] property_block: fields: [Agent_Ref, Rightmove_ID, Rightmove_URL, Change_Type] note: >- Error responses echo the Agent_Ref supplied in the request where possible; if the error occurs before the message can be processed (an authentication or connection error) the Agent_Ref may be absent. errors: array: Errors fields: [Error_Code, Error_Description, Error_Value] warnings: array: Warnings fields: [Warning_Code, Warning_Description, Warning_Value] code_registry: url: https://adfapi.rightmove.co.uk/v1/property/errorcodes reachable_anonymously: false probed: '2026-07-26' http_status: 403 gate: mutual TLS (Rightmove-issued X.509 client certificate) harvested: false schemas: url: https://adfapi.rightmove.co.uk note: >- The JSON Schemas for every call are served from the same mutual-TLS host and are likewise unreachable anonymously (403). Schemas are also obtainable by emailing adfsupport@rightmove.co.uk. agent_reporting: note: >- Warning codes and full warning text are additionally surfaced to the agent inside the Real Time Data Feed Error Report in RightmovePlus — an authenticated web surface, not an API. covers_calls: - SendPropertyDetails - OverseasSendPropertyDetails - RemoveProperty - GetBranchPropertyList - AddPremiumListing - AddFeaturedProperty - RemoveFeaturedProperty - GetBranchPerformance - GetPropertyPerformance - GetBrandEmails - GetBranchEmails - GetPropertyEmails
