Smartsheet

Read and write Smartsheet workspaces, sheets, rows with column-title mapping, discussions, comments and attachments metadata.

Use project sheets as operational trackers: push records into rows and pull status, owners and dates back out.

Data types

Validation status

Implemented · fixture tested.

Implementation is checked against provider-shaped fixtures for every action, authentication failures, rate limits, pagination and duplicate safety. Provider sandbox and authorised account validation are recorded separately when credential-backed runs are completed.

Authentication

Smartsheet API access token

Plans and access

Smartsheet Business and Enterprise plans (the API is restricted to these plans). Access follows the sharing permissions of the user who owns the access token.

Test environment

Use a Smartsheet trial or a developer account; there is no separate sandbox host.

Rate limits

300 requests per minute per token; file attachments and cell history count 10x. HTTP 429 on excess.

Provider events

Smartsheet webhooks with callback verification and HMAC signatures. Nexra event triggers are not yet available; flows run on demand or on a schedule.

Before you build a flow

Row writes take column IDs. Reads return cells keyed by column title as well as by column ID; map titles to IDs with List columns.
Smartsheet Gov (api.smartsheetgov.com) is not offered.
Attachment metadata is read and URL attachments can be added; file uploads and downloads are not transferred.
Smartsheet has no idempotency key; uncertain row additions are not repeated automatically.
Deletes, sharing and automation rules are not implemented.
