For at least thirty years, people have talked about the "paperless office." With cloud-based services, it may finally be possible. Yet, for many organizations, a major hang-up is contracts, which require ink signatures. In our first public API report, sponsored by DocuSign, we looked at electronic signature platforms. Specifically, we examined the features and developer friendliness of e-signature APIs, which allow non-ink signatures to be automated and integrated into business processes. Without a doubt, e-signatures are a growing field, as evidenced by the recent acquisition of EchoSign by Adobe.
