# ReturnedZaps Returned ZAPs are mailings that were successfully sent but returned because the carrier couldn't physically deliver them for some reason. \ We will log any ZAPs returned as well as the reason they weren't delivered if the carrier provides one. This information can be retrived on a submission level via the following endpoint. ## GET /api/v1/RejectedRecords/{submissionId} > ```json {"openapi":"3.0.1","info":{"title":"ZAPI","version":"1.0.0"},"security":[{"Basic":[]}],"components":{"securitySchemes":{"Basic":{"type":"http","scheme":"basic"}}},"paths":{"/api/v1/RejectedRecords/{submissionId}":{"get":{"tags":["RejectedRecords"],"parameters":[{"name":"submissionId","in":"path","required":true,"schema":{"type":"string","format":"uuid"}}],"responses":{"200":{"description":"Success","content":{"application/json":{"schema":{}}}},"400":{"description":"Bad Request"},"401":{"description":"Unauthorized"},"404":{"description":"Not Found"}}}}}} ``` Records that are submitted against campaigns with dynamic images have their own rejection batching to make it easier to resolve any image related issues and resubmit the data. ## GET /api/v1/RejectedRecords/DynamicImages/{submissionId} > ```json {"openapi":"3.0.1","info":{"title":"ZAPI","version":"1.0.0"},"security":[{"Basic":[]}],"components":{"securitySchemes":{"Basic":{"type":"http","scheme":"basic"}}},"paths":{"/api/v1/RejectedRecords/DynamicImages/{submissionId}":{"get":{"tags":["RejectedRecords"],"parameters":[{"name":"submissionId","in":"path","required":true,"schema":{"type":"string","format":"uuid"}}],"responses":{"200":{"description":"Success","content":{"application/json":{"schema":{}}}},"400":{"description":"Bad Request"},"401":{"description":"Unauthorized"},"404":{"description":"Not Found"}}}}}} ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://userguide.zappost.com/zap-api/api-endpoints/returnedzaps.md?ask= ``` The question should be specific, self-contained, and written in natural language.
