Frequently asked questions

  • How do I get started?

    Simple. Sign up for a free trial of mSign. You’ll find your API key within the settings tab. You can use our extensive API docs to start sending API requests right away.

  • Do you offer a free testing account?

    Yes. Simply sign up for an mSign account and you’ll automatically get a 14-day free trial (no credit card required) to start using all the API features available with mSign.

  • How does embedded signing work?

    You won’t have to send your users to mSign to get your documents signed. Instead, embedded signing enables you to create an embedded document within your website or app where users can sign as part of a seamless (and non-branded) experience.

  • Where can I view API docs and get additional help?

    You can view our API docs here. We also have a variety of resources available in our Help Center. If you have more questions, you can reach out to our knowledgeable staff using the chat window in the lower right corner of your screen or emailing support@documo.com.
