Smartsheet SDK for JavaScript Build Status Coverage Status npm version

This is a client SDK to simplify connecting to the Smartsheet API from Node.js applications.

System Requirements

The SDK supports Node.js versions 6.x or later.


To install this SDK, simply run the following command in a terminal window:

npm install smartsheet


The Smartsheet API documentation with corresponding SDK example code can be found here.

Example Usage

To call the API, you must have an access token, which looks something like this example: ll352u9jujauoqz4gstvsae05. You can find the access token in the Smartsheet UI at Account > Personal Settings > API Access.

The following is a brief sample using promises that shows you how to:

  • Initialize the client
  • List all sheets
  • Load one sheet
// Initialize the client
var client = require('smartsheet');
var smartsheet = client.createClient({
  accessToken: 'll352u9jujauoqz4gstvsae05',
  logLevel: 'info'

// The `smartsheet` variable now contains access to all of the APIs

// Set queryParameters for `include` and pagination
var options = {
  queryParameters: {
    include: "attachments",
    includeAll: true

// List all sheets
  .then(function (result) {
    var sheetId =[0].id;                // Choose the first sheet

    // Load one sheet
    smartsheet.sheets.getSheet({id: sheetId})
      .then(function(sheetInfo) {
      .catch(function(error) {
  .catch(function(error) {

Although the example above is using promises and the API documentation samples use promises, you could also access the APIs in this SDK by using callbacks.

// List all sheets using callbacks
smartsheet.sheets.listSheets({}, function(error, data) {
  if (error) {
  } else {

See the node-read-write-sheet project for a code example that shows how to call methods to read and write to a sheet using this SDK.

Basic Configuration

When creating the client object, pass an object with any of the following properties to tune its behavior.

  • maxRetryDurationSeconds - The maximum time in seconds to retry intermittent errors. (Defaults to 15 seconds.)

  • logLevel - Set to 'info' to log each call and return value to the console.

Advanced Configuration Options

Logging Configuration

This library leverages winston for logging.

Supported log levels are:

Level What is logged
'error' Failures only
'warn' Failures and retries
'info' Each call URL and response code
'verbose' Payloads, truncated to 1024 characters
'debug' Full payloads
'silly' Full payloads and HTTP headers

You may create your own winston container or configure the default winston.loggers container, adding a logger named 'smartsheet'. Specify this container using the configuration option loggerContainer. (winston documentation on configuring loggers.)

If you want to use your own logger, pass a logger object as the configuration option logger that implements the following methods:

  • silly, verbose, debug, info, warn, error - Standard logging methods
  • log - Similar to the above, but accepting the logging level string as its initial parameter; the log level is guaranteed be one of the above options.

Retry Configuration

For additional customization, you can specify a calcRetryBackoff function. This function is called with two arguments:

  • The first accepts the index of the retry being attempted (0 for the first retry, 1 for the second, etc.)
  • The second accepts the Error Object that caused the retry.

The function must return the number of milliseconds to wait before making the subsequent retry call, or a negative number if no more retries should be made.

The default implementation performs exponential backoff with jitter.


The source code comes with several scripts for running tests:

Script Action
npm run test Runs all tests. Note, the mock API tests will fail unless the mock server is running
npm run test-functional Runs only functional tests
npm run test-mock-api Runs only mock API tests. Clone the Smartsheet SDK tests repo and follow the instructions from the README to start the mock server
npm run coverage Runs functional tests and reports on code coverage
gulp jshint Runs JSHint against the codebase
gulp [watch] Watches the codebase and runs JSHint whenever changes are made
