AS Abbas S. Co-founder, Chief Product Officer Small-Business (50 or fewer emp.) 9/1/2022 "Best Solution for Embedded Signing" 4/5 What do you like best about SignNow API? From a technical standpoint, SignNow's API was simple to follow and implement. With an hour of work, I got the sequence of my intended workflow figured out and tested. Also their leadership valued long-term relationships and was willing to work with us on a win-win deal structure. Review collected by and hosted on G2.com. What do you dislike about SignNow API? The Stamp field comes across as an afterthought. It assumes that the document must be scanned with a high-res scanner, not an uploaded stamp picture. They have a powerful embedded sending, which uses their email template with very few places to personalize by us. So we had to develop our email functionality to include our branding the way we wanted. Review collected by and hosted on G2.com. What problems is SignNow API solving and how is that benefiting you? We were looking for an embedded eSignature platform with a rich set of APIs that could take smart tags (sent by us) with a smooth mobile UX. We looked at quite a few solutions, but they were either not looking great when opened in a phone, lacked an embedded functionality, or were too expensive. SignNow managed to offer the functionality we wanted at a reasonable starting price point. In addition, they eventually added mobile SDK on top of their iFrame functionality, which was great.

Robust and easy to use API for combining and generating e-signature documents, with embedded signing or email invites Review collected by and hosted on G2.com. What do you dislike about SignNow API?
