"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.

5/5

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?

Embedded invite and sending invite are treated as separate so if 2 signatures are required the countersign needs to be done as an embedded invite also Review collected by and hosted on G2.com.
