What do you want to build?

Automate workflows in your own account

Set up backend scripts, create scheduled jobs, or just test API endpoints with your own data.

Get started by creating a self client. No need for redirect URIs or multi-step authorization flows.

Get started with self client

Build apps and integrations for other users

Build an app and let users access it after getting the required permissions from them.

Get started by registering your app in the API console, and learn how to get delegated access from users through secure OAuth flows.

Register your app

Built for developers

Our REST API framework features power reliable, scalable integrations.

Industry-standard authentication

Zoho APIs are authenticated using the OAuth 2.0 standard, which supports every app type including web apps, JavaScript apps, mobile or desktop apps, and IoT devices.

Learn how OAuth works

Self client for automation & testing

Set up app-to-app communication without any user interaction, or test API endpoints using our Self Client option. Simple authorization without the need of any redirect URIs.

Try self client

Built-in multi-region support

Build once and deploy in every region. With multi-DC support, you can enable your app to be accessible for Zoho users in any region.

Incremental authorization

Don't want to ask for all permissions upfront from a user? Start with necessary permissions and request more when your app needs them.

Frequently asked questions

  • Do I need a Zoho account to use the APIs?

    Yes. You need a Zoho account to use Zoho APIs. You would also need to register your application and obtain the credentials. You can create a free account to get started.

    Create account

  • What is Zoho API Console?

    The API console is where you register your application and manage your credentials. It's the starting point for accessing Zoho APIs.

    You can register different application types including:

    • Web applications (server-based)
    • JavaScript applications (client-based)
    • Mobile and desktop applications
    • IoT and limited-input devices (non-browser based)
    • Self client (for automating and testing)
    Go to API Console

  • How are Zoho APIs authenticated?

    Zoho APIs use OAuth 2.0, the industry-standard authorization protocol. Instead of sharing passwords, users authorize your app to access their data through secure token-based authentication.

    Zoho supports different OAuth flows based on the type of your application.

    Learn about OAuth flows

  • Can I test the APIs without affecting my production data?

    Yes. You have two options.

    Sandbox environments: Many Zoho apps (CRM, Books, Desk, etc.) provide sandbox environments where you can test integrations safely without affecting live data.

    Self client: Generate tokens without any user-authorization flows to try out the API endpoints with your own account data.

    Learn about self client

  • How do I get started with Zoho APIs?

    Here's a quick start path:

    • Browse the API directory to find the Zoho products you want to integrate with.
    • Register your app in the API console to get credentials.
    • Authenticate using the appropriate OAuth flow for your app type.
    • Make your first API call using the obtained access token.

  • Where can I find the documentation for Zoho APIs?

    Each Zoho product has its own comprehensive API documentation. You can browse all available APIs by category in our API Directory and find documentation for each there.

  • How do I support users in different regions accessing my app?

    Zoho users' accounts are present in different data centers across the globe. To enable users from different regions to access your app, you can configure multi-DC support from the API console. You need to configure region-specific endpoints in your app to accommodate for users in other regions.

  • Do Zoho APIs have rate limits?

    Some Zoho APIs have rate limits that vary by product and subscription plan. For specific limits, check the documentation for the Zoho product you're integrating with.
