What is holding SendGrid back
- OAuth and OpenID metadata, 5 points lost. No OAuth or OpenID metadata was found on the 4 hosts that answered. 10 other hosts did not answer the scanner and could not be checked. Agents cannot discover where to send a customer to approve access. Fix: Publish /.well known/oauth authorization server and /.well known/oauth protected resource for the customer facing APIs.
- Developer and data sharing program, 4 points lost. No developer portal or data sharing program was found on public pages. Fix: Document the program, the standard in use for example FDX in US banking, the supported partners and a sandbox.
- PKCE and client registration, 4 points lost. No authorization server metadata, so PKCE and client registration could not be confirmed. Fix: Require PKCE with S256 and support client ID metadata documents or dynamic client registration for approved agent clients.
- Passkeys at sign in, 4 points lost. No passkey signal was found on the sign in page or in the published pages read. A prompt that starts only after a person types is not visible to the scan. Fix: Offer passkeys with conditional UI on the sign in page and for step up approvals.
What already works
- Sign in page loads for a declared agent in a browser
- Content available without running scripts
- Home page for a declared agent
