Smartsheet API

A RESTful interface for automating sheet operations, managing users, and synchronizing enterprise data at scale.

The Smartsheet API provides programmatic access to the platform's core engine, allowing developers to execute CRUD operations on sheets, rows, and cells via standard HTTP methods. It supports OAuth 2.0 for secure authentication and delivers responses in JSON format. Engineers use it to bridge the gap between CRM systems like Salesforce and project dashboards, automate update requests, and manage large scale user provisioning across thousands of workspaces. With rate limits set at 300 requests per minute per token, it is built to handle high volume data synchronization and complex cross sheet reporting workflows.
