A tool to validate your headers

[Maud N (Chrome)]

Hi everyone,

A tool is available here to help you detect common misconfigurations in your Attribution-Reporting-Register-Source and Attribution-Reporting-Register-Trigger headers. The tool detects issues such as wrong formatting (example: source_event_id must be a string), missing fields, typos on field names, key pieces that don't match, invalid JSON, over-limit trigger data, and more. 

Next steps

We're also working on a Chrome DevTools integration so that these precise misconfiguration warnings pop up directly in the Issues tab. Until then, use the header validation tool to gain certainty that your headers are properly configured. 

Example usage

• With a valid header

• With an invalid header

• Note the Copy Link function on the page, to share your validation results with others.
