Try These Prompts

Upload the file ~/Documents/NDA_2026.pdf and create a signing transaction. The signatory is Alice Müller (alice.mueller@acme.de, +49 170 1234567). She should sign with SES (simple electronic signature). Send her an email notification.
Full end-to-end flow: uploads a PDF, creates a transaction with one SES signatory, and triggers email notification.
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.

AES flow: presents the terms & conditions for your review and acceptance, then returns the video identification URL to open in your browser.
