Overview

Zoho Writer APIs use OAuth 2.0 for authentication. This page gives you an overview of the authentication process. For complete details on OAuth 2.0 flows, registration, token management, and more, refer to the Zoho OAuth 2.0 documentation.

How it works

To access Zoho Writer APIs, your application needs an access token obtained through one of the OAuth 2.0 flows. At a high level, the steps are:

1. Register your application in the Zoho API Console.

2. Get consent from the user to access their data.

3. Exchange the consent for an access token.

4. Call Zoho Writer APIs using the access token.

Token expiry

Access tokens expire periodically. The expiry duration is given as expires_in (in seconds) in the access token response. To maintain uninterrupted access, request an optional refresh token, store it, and use it to generate new access tokens as needed.

Multi-DC support

Zoho operates data centers in multiple regions. If your application serves users across regions, enable Multi-DC support in the API Console and use region-specific endpoints for both OAuth and Zoho Writer API calls. See Multi-DC Support.
