Small-Business (50 or fewer emp.) 2/29/2024 "Easy embedded document signing" 5/5 What do you like best about SignNow API? The signNow API was super easy to get started with for embedded signing. We implemented it within a month, going from no knowledge of SignNow to live in production for customers. Since setting it up over three years, it's been mostly hands off with very little issues. With the embedded flow, not our sales people as well as the customers can still within our platform to manage and sign documents. Review collected by and hosted on G2.com. What do you dislike about SignNow API? They don't really have great support for a staging environment. They do have an evaluation environment but those accounts expire and are not attached to your main account. With the main account there is a way to make use a test key to not use invitations. Then when ready, you can mark it live. However, it doesn't work quite 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 used to email quotes as PDF's to the customers and they had to print, sign, scan and email them back which was obviously a pain and took forever. Now we're automatically generating quotes that can be e-signed, which makes everyone's lifes easier and greatly improves the turnaround time. Review collected by and hosted on G2.com.

Small-Business (50 or fewer emp.) 3/1/2024 "It meets the bar but there are several things needed to make it a great fit for our needs" 3.5/5 What do you like best about SignNow API? 1) The embedable widgets were easy to incorportate and pretty easy to customize 2) Nearly every endpoint functioned as the docs described 3) The ability to customize themes in the UI and use via the API was nice. Review collected by and hosted on G2.com. What do you dislike about SignNow API? 1) I wish there was a "filling out" mode for before a user is signing and is filling out the form and we could allow users to save progress. We regularly hear I spent x time filling it out but had to stop, why can't you save my progress so I don't have to start over. 2) Pre-selecting radio buttons and checkboxes wasn't possible during document creation like we are able to pre-fill for other data types. This required a silly work around of creating the doc, then editing the doc with the desired pre-selection options for the radio buttons. This was additional work and slowed down the creation procress. 3) I wish we could provide a custom list of varables for users to use during template creation. In order for docs to work with pre-filling we need them names a specific way and getting users to follow that schema is impossible / terrible UX thus we haven't rolled out this ability to our users despite them asking for it. 4) This is mute for us now as we solved it, but the ability to have signers and assigned fields removed if no signer is passed in would have been a time saver. There are potentially 6-8 signers on a given template but for any given use it could be less thus before we created every permutation. Now we create the max signers template and during doc creation reduce the number of signers and their assigned fields to those needed...would be nice if ya'll handled that. 5) Document creation time could be improved. We've done some optization on our end but it still takes ~30-60 seconds for larger packets. Review collected by and hosted on G2.com. What problems is SignNow API solving and how is that benefiting you? The ability to support many different document templates and combine them into custom groups and send for signature.

SignNow API is making our waiver signing and storage process a breeze compared to our previous method of filling, downloading, verifying, and then uploading a PDF file!

The API was easy to use and we were able to implement it within 30 days. Our SaaS software uses SignNow to resell eSignatures.
