Envelopes that gather documents and signers, factors that prove identity, vaults that organize what was signed, an API to wire it into your system: the signing flow covered from sending to storage.
Each page below shows how the feature works in practice.
The signing flow itself, the guarantees around it and the connection to what your company already uses. Each card leads to the feature's full page.
Multiple documents and multiple signers sign in a single flow, sequential or parallel, ending in a certificate of completion with the full history.
The fixed text of a recurring document stays ready; typed fields mark what varies and every change produces a new version.
From a code by email to PIX validation and a selfie with liveness detection: configurable factors that prove who signed.
TLS at the edge, AES-256-GCM for secrets at rest, PAdES signatures embedded in the PDF and a timestamp on every signature.
Each document lives in a vault, and the vault defines who can see it: the account's, a user's or shared with a group.
Volume, completion rate and average signing time by period, plus audit reports that reconstruct each case.
Upload the document, build the envelope with signers and validations, publish and track the status in REST calls.
Published, signed, declined: envelope events arrive as a POST to your endpoint the moment they happen.
Your domain, your emails, your colors and even the digital certificate that seals the documents, with no reference to Signater.
Not everything needs a full page. These capabilities round out the day-to-day operation.
Find any document by identifier, name, description or email. Handy when you remember the case, but not where it was stored.
Platform, signing flow and messages in English, Portuguese, Spanish, French, German and Italian. Each signer signs in the language they understand.
Email with failover across multiple providers, SMS, WhatsApp and real-time notifications inside the platform. Triggers follow every step of the flow, on the channels you configure.
Set the date and the envelope publishes itself, with the signers notified. The deadline works the other way around: an envelope that has not completed expires automatically.
Register frequent signers once and select them on the next envelopes, without retyping their details.
Deletion on Signater is logical: the document goes to the trash and can be restored from there. A wrong click can be undone.
Upload Word, text, spreadsheet, e-book or image files in around 15 formats. Everything becomes a PDF on upload, hash already computed and pages counted.
