RIA Sign
Claude connectorCommunityElectronic document signing via WhatsApp
RIA Sign lets you send documents for electronic signature and track them from Claude. Signers receive the request on WhatsApp and sign inside a native WhatsApp Flow or on a mobile web page, with no app install or account required.
What you can do:
- Send a PDF for signature to one or more signers, with signing order and optional identity checks (selfie and ID photo)
- Draft a contract from a plain-language description, or send contract text you already have
- Save reusable contract templates with placeholders that each signer fills in when signing
- Track envelope status, send reminders, cancel envelopes, and download the signed PDF
- List your contacts, templates, and usage
Signatures follow Brazilian law (Lei 14.063/2020 and MP 2.200-2/2001) at the simple or advanced level. Each completed document gets a certificate page with an audit trail, an RFC 3161 timestamp, a server signature, and a public verification link.
Authentication uses OAuth with your RIA Sign account. Sending a document dispatches real WhatsApp messages to the signers.
