What This Skill Covers
- Verify a signed request using the HMAC and SHA-256 algorithms or return a 403.
- Main sections:
Tags,Validate signed requests using the WAF.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
