About Hellosign

HelloSign was an electronic signature platform acquired by Dropbox in 2019 and rebranded as Dropbox Sign in 2023. The legacy API domain api.hellosign.com still routes to Dropbox Sign's API. It allows businesses to send, sign, and manage legally binding documents with audit trails, templates, and automated reminders. The SharePoint integration was discontinued in March 2026 and Dropbox Forms was sunset in September 2025.
