[attach a PDF] I want to sign this with QES. I'm Krzysztof Tucholski, +48793405338, k.tucholski@gmail.com — and I want to sign it right here, in this chat.
QES without leaving the conversation: the assistant asks how you want the link delivered, you choose “here”, and it hands you one to open in the embedded browser.
[attach a PDF] Sign this with SES. The signatory is Alice Müller (alice.mueller@acme.de, +49 170 1234567) and she should get the link by email.
Drag the PDF into the chat — the assistant sends it to Signicat itself, creates the transaction and triggers the email.
Create a signing transaction for the already-uploaded document (fileId: 7f3a9c2e-...). Two signatories: 1) CEO Bob Johnson (bob@startup.io, +31 6 12345678, QES, signs first) and 2) CFO Clara Rivera (clara@startup.io, +49 151 9876543, SES, signs second). Notify both via email and SMS.
Multi-party sequential signing with mixed signature levels (QES + SES) and dual notification channels.
Sign the document headlessly for transaction 3fa85f64-5717-4562-b3fc-2c963f66afa6, signatory id "employee". Then verify with OTP code 847291.
Headless SES signing: drives the click-to-sign flow programmatically, then confirms with the SMS OTP you received.
I need to complete an AES (advanced electronic signature) for this signing link: https://web-api.test.identity.signicat.global/onboarding/proceed?proceedToken=abc123xyz. Show me the terms and conditions so I can review and accept them, then give me the video identification link.
AES flow: presents the terms & conditions for your review and acceptance, then returns the video identification URL to open in your browser.
