Smartsheet API: what you can do and how to use it with AI agents
The Smartsheet API lets you read and update sheets, rows, columns, attachments and comments, as well as reports and workspaces. PMOs, operations and IT teams that manage projects and trackers in Smartsheet use it. Access is through an API token generated by the user, or OAuth 2.0.
What the Smartsheet API offers
Sheets
Creating, reading and copying sheets and templates.
Rows and cells
Adding, updating and deleting rows and values.
Columns
Column types, dropdown lists and contacts.
Attachments and comments
Files and discussions on rows and sheets.
Reports and dashboards
Reports that consolidate several sheets.
Webhooks

How to access the Smartsheet API
- Public APIAn API token generated in the user settings, sent as a bearer token, or OAuth 2.0 for apps. Permissions follow how the sheets are shared.
- There are per-minute request limits, so group updates into batches.
- The token inherits everything the user can see, so use a dedicated user.
- Shared sheets may hold sensitive data.

What an iTeam agent does with the Smartsheet API
Project status without a manual sheet
The agent asks owners in Teams how their tasks are going and updates the rows of the schedule.
Delay flagged
The agent finds tasks with a past due date and an open status and tells the project manager.
Request that becomes a row
Requests received by email become rows in the demand sheet, with requester and priority.
Summary for leadership
Every week, the agent reads the portfolio report and sends the projects at risk.
From the credential to the agent at work, with approval
Generate the token or authorize the app
Use an integration user with access only to the sheets needed.
Store it in the iTeam vault
The token stays in the vault, and each agent updates only the columns it is cleared for.
Test with approval
Deleting rows and changing structure go through human approval.
