Send pre-filled offer letters to new hires for signature the moment an offer is extended — automatically, from your HR system or ATS.
Offer letters are time-sensitive. A candidate who receives a slow, manual offer process doubts your organisation before they even start. Yet most HR teams still export a Word doc, fill in the details, convert to PDF, attach to an email, and wait. When the candidate signs a paper copy and scans it back, the process is finally done.
When a candidate is marked as hired in your ATS or HR system, trigger an API call. eSignature API generates the offer letter PDF pre-filled with the candidate's name, role, salary, start date, and any other variable terms — and sends it for signature immediately. The candidate receives a professional, branded document to sign on any device. You receive the signed copy via webhook, ready to store in your HR system.
Design your offer letter template with all standard terms. Mark variable fields — candidate name, role title, salary, start date, manager name — for dynamic population from your HR data.
When a candidate is marked as hired, trigger an API call via Zapier, Make, or direct REST integration. Pass the candidate's details to the API — the offer letter is generated and sent for signing automatically.
The candidate receives an email with a signing link. They sign on any device. You receive a webhook with the completed offer letter — ready to attach to the candidate record in your ATS.
When a candidate stage changes to "Offer Accepted" in Greenhouse, Lever, or Workday, trigger automatic offer letter generation and signing.
Send offer letters to multiple candidates simultaneously using parallel signing — each candidate receives their own personalised document.
HR signs first, then the candidate countersigns. Configure sequential signing so the order is enforced automatically.
Send an offer letter, an NDA, and a data protection agreement in the same signing request — all completed in one session.
