The Smartsheet API enables licensed Smartsheet users to programmatically access and manage their organization's Smartsheet account and data. It is designed to be simple and intuitive, and is based on widely accepted standards and conventions, including REST, JSON, and HTTP success and error codes. If you already have experience with other publicly available RESTful APIs, you will feel right at home.
Smartsheet now uses 37 character API keys. Your 26 character API keys will still work but it’s a good idea to update your existing keys to take advantage of the additional security.
To generate an API key:
- At the bottom right corner of the screen, click your account icon and then select Apps & Integrations.
- From the left menu, select API access. From this screen, you can either generate new tokens (keys) or revoke existing tokens.
