Frequently asked questions

  • How is an API plan different from other paid plans?

    The API plan gives you access to Zoho Sign features only through APIs (automation), whereas our other paid plans are offered to users who are interested in using features directly from Zoho Sign's web and mobile interface.

  • How does the API licensing work?

    You need to purchase Zoho Sign API credits in denominations of 100. For example, at per credit, you can purchase a minimum of one hundred credits to be added to your account for . Each document signature request you raise using API consumes an API credit.

  • What if I want to use Zoho Sign with its built-in interface and also use APIs for integration?

    We encourage the purchase of an API-only license only if you intend to integrate Zoho Sign with other applications for automated usage and have minimal use for the Zoho Sign web and mobile applications. If you want to make use of the Zoho Sign web and mobile apps alongside integrated API usage, we recommend purchasing the Enterprise license and a sufficient amount of API credits as add-ons. 

  • What do I get for one credit?

    Every time a document signature request is created and submitted to be sent for signatures using API, one API credit gets deducted from your account. API credit consumption is strictly confined to sending documents out for signature. Other API actions such information fetch calls, update calls, user & account management calls do not consume any API credits.

  • Do I have to pay to try the API?

    No. You can sign up for the trial account that offers all of the features, including the API. You can send up to 50 test documents by passing 'testing=true' as a parameter in API calls without needing API credits. When you're ready, you can purchase sufficient API credits to meet your requirements.

  • How do you notify me when I'm running out of credits?

    You can configure add-on alerts in your account settings where you can set low and critically low API limits. You will receive an email reminder to purchase additional API credits when the credits remaining in your account drop to these limits.

  • How long are my credits valid?

    Your API credits don't have an expiry date. They remain valid as long as your account has a valid API-only or Enterprise license.

  • Do you offer dedicated API technical support?

    Yes. We provide 24/5 API technical support for both trial and paid users, except on public holidays.
