OAuth 2.0 for Zoho Sign's API access
Zoho Sign API uses OAuth 2.0 authorization, a widely used protocol for granting secure and limited access to a user's data or resources without the need to share the user's credentials (such as a username and password) directly.
You need to include the OAuth access token in the header of every call made to our API. The steps to register and create OAuth tokens can be found here.
OAuth Scopes
You must provide the OAuth scopes when you create the tokens. The OAuth scopes required will vary based on the types of API calls that you would need to make.
| API Types | OAuth Scopes |
| Document management | ZohoSign.documents.CREATE ZohoSign.documents.READ ZohoSign.documents.UPDATE |
| Template management | ZohoSign.templates.CREATE ZohoSign.templates.READ ZohoSign.templates.UPDATE |
| User management | ZohoSign.account.CREATE ZohoSign.account.READ ZohoSign.account.UPDATE |
