External Supplier KYC & Document Upload Portal (/r/:token — Microsoft Forms Fix)
Bypass the Microsoft Forms external file-upload restriction! Dispatch a single-use /r/:token intake portal where external vendors submit structured fields + up to 5 SHA-256 verified documents.
Why Makers Use This Blueprint: Microsoft Forms disables file uploads for external respondents, forcing IT teams to create risky SharePoint anonymous folders or manage Entra B2B Guest accounts.
