# Payload Validator This channel is a tool to help you validate event payloads sent by your site. This is especially helpful when you are developing a headless website where you send events using our browser SDK or are calling the CDN endpoint directly using POST requests. All payload validation errors will then be reported in the **Analytics** section of your site within the EdgeTag app which should help you identify which event payloads are problematic and might be causing problems. ### Details Channel name: validation --- # 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://docs.edgetag.io/channels/payload-validator.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
