Frequently asked questions

  • What is an API call?

    A single document opened in Zoho Office editor (e.g., Writer) equals "1 API call".

  • How do I calculate my API Usage in terms of API calls?

    The Office Integrator usage depends on the number of "open document" requests sent to Zoho. We update the API call counter by 1 with every new request.

    For example, if you open 5 different word documents (one at a time), it will be counted as 5 API calls. Similarly, a single document opened multiple times (say 5) will equal 5 API calls.

    Also, 'Save' requests are not counted as part of API calls.

  • What's the difference between Commercial and Non-Commercial pricing plan?

    Commercial: For partners who sell Office Integrator-based solution to users for a "fee".

    Non-commercial: For partners and non-profits who offer the Office Integrator-based solution to users for "free".

    Partners can choose from either of the pricing plans based on the number of API calls the establish with Zoho per month.

  • Can I try Office Integrator before subscribing to a paid plan?

    Yes, you can. We offer a Free plan with limited API calls to partners integrating Office Integrator solution. You are permitted a total of 50 API calls/month under the Free plan.

  • Can I change my Office Integrator subscription plan or buy additional API calls?

    Of course, you can! Login to your Zoho Office Integrator account, click on the "Change Plan" link from the dashboard and follow the steps on the Subscription page to switch to a new plan. There is also an option to buy additional API calls in 2000, 5000 and 10,000 unit increments for your existing plan.

  • What if we exceed our Office Integrator usage and fail to upgrade?

    You will receive automatic email alerts from Office Integrator Team when you exceed 75% & 90% of API Usage of your current subscription plan for any particular month. Once you hit the subscribed plan limit, you will get the "API Usage Exceeded" error and the API service may be interrupted.

  • What are my payment options?

    We accept payment via Visa, MasterCard, American Express and PayPal. We also accept payment via bank transfer or check transfer for yearly subscriptions. For more details, please contact:

  • Can I upgrade, downgrade or cancel a plan at anytime?

    Absolutely. Zoho Office Integrator is a month-to-month, pay-as-you-go service. You can upgrade, downgrade or cancel at any time.

  • Do all users need to have a Zoho account for using Office Integrator?

    Office Integrator-based solutions does not require each user to have a Zoho account as all API requests are authenticated through a single API key.

    The Office Editors integrated into your web application will validate that specific API key for all document open/edit requests. Further details here.

  • How different is Zoho Office Integrator to Microsoft Online Office WOPI integration?

    It's mandatory for all MS Office (WOPI) business users to have an Office 365 subscription and a Microsoft account while Zoho Office Integrator does not impose such restrictions on users of businesses integrating its Online Office solution.

    Businesses only need to set up a single Zoho account for authenticating Office Integrator API requests. Users don't have to create a separate account with Zoho.
