"Using the Legalesign API is a breeze, sending and processing e-signed documents couldn't be easier"

James

Director of Information Systems, Ready Project

Integrating Legalesign via its API into a customers solution worked flawlessly. The attention to detail within the front end of the product is great and the backend API is equally thought through. Any questions that I did have were answered very quickly and thoroughly...The quality of integration is great, and if you have specific features you need I would highly recommend partnering with Legalesign."

"I am definitely planning on using the Legalesign e-Signature API again soon. I appreciated the support and attention to security."

Arthur King

Head of IT, N4Gtv.com

I would recommend that anyone looking for a document signing solution to have a good look at Legalesign. The system is very reliable and has great functionality + via their API you can achieve excellent levels of integration with existing software. However the best part is without doubt their customer service. A lot of online providers shout about their support; these people actually exceed what you expect.

I've integrated Legalesign into a CMS product. The use case was for users to have to sign an NDA before gaining full access to the system. I managed to do this with ease using the Legalesign REST API such that the entire process of user sign-up, NDA signing and granting full access to the system is entirely automated. Their support team are knowledgable on development related issues and are very responsive. I also trialled Adobe EchoSign... and without a doubt, Legalesign most definitely represent the best solution when it comes to features, flexibility and robustness versus pricing.
