"Reliable E-Sign"

4/5

What do you like best about BoldSign eSignature API?

I wanted an affordable alternative of Adobe for signing of my contracts, Boldsign provides me fast and secure option for that. As a software developer, I have integrated this API into my services which enables my clients to easily sign the documents, at the same time I can track the status and download the signed documents. API success rate is quite impressive, also enables to upload multiple formats of files. Review collected by and hosted on G2.com.

What do you dislike about BoldSign eSignature API?

Little difficult to integrate, Boldsign should provide more tutorials or documentation for beginners to use it effectively, during initial phase. Review collected by and hosted on G2.com.

What problems is BoldSign eSignature API solving and how is that benefiting you?

Boldsign helps me to legally sign my documents end to end securely without the dependence of any third party service or physical token. The API Response time is also fast (around 400 ms). It was easy to integrate the functionality on my existing solutions, without spending time and money on development and maintenance of it by my own company. It lets me upload my documents, I can choose the signature fields also, I can modify the signed documents look by attaching my brands and logos to authorize it as per my organization. It generates a copy of signed document and sends it both to the recipient as well as the authenticating authority once the paper is signed. Review collected by and hosted on G2.com.
