What Are the Limitations of Smartsheet API?
While Smartsheet continuously enhances its platform, certain limitations still apply to ensure optimal performance and reliability. Here are the key limitations to be aware of:
Row and Cell Limits:
- Adding or Updating Rows: Limit your request to 500 rows at a time.
- Sheet Cell Limit: A sheet cannot exceed a total of 500,000 cells. To calculate this, multiply the number of columns by the number of rows. For example:
- A sheet with 20,000 rows can have a maximum of 25 columns.
- A sheet with 400 columns can have a maximum of 1,250 rows.
Inbound Cell Links:
- Any one sheet can have up to 500,000 inbound cell links.
- For Smartsheet Gov, the inbound cell link limit is 100,000.
Cell Content Limit:
- No cell can contain more than 4,000 characters.
Report Data Retrieval:
- When using the
GET /reports/{reportId}
call with paging, the default is 100 rows. The maximum number of rows that can be returned per request is 10,000. - Reports are limited to 50,000 rows.
Email Sharing:
- You can send up to 1,000 emails per API call when sharing.
Connector and Feature Limits for Large Sheets: The following features are not supported for sheets with more than 5,000 rows or more than 200 columns:
- Bridge by Smartsheet
- Quip connector
- Tableau connector
- PowerBI connector
- Zapier connector
- Google Docs Merge connector
- Google Forms sync connector
- LiveData connector
- Calendar App
- Looping
These limitations are critical for developers and users to consider when designing workflows and integrating Smartsheet into their systems. Adhering to these constraints ensures smoother operation and avoids potential issues related to performance and data handling.
Step-by-step Guide on Using Smartsheet API
Whether you're looking to automate repetitive tasks, integrate Smartsheet with other tools, or build custom applications, the Smartsheet API is your gateway to enhanced productivity. Let's walk through the basics of getting started with the Smartsheet API, from setting up authentication to making your first API call.
Step 1: Sign up as a developer
Go to the Smartsheet developer sign-up page and register a developer account. (No need to sign up if you already have a Smartsheet account on Business and Enterprise plans.) The developer account gives you access to "Developer Tools," where you manage your app. In "Developer Tools," complete any required fields in your developer profile.

Step 2: Create a new app
In "Developer Tools," click on" Create New APP".

You will be directed to the app detailed page where you will be prompted to provide various details about your app, including:
- App Name: Give your app a meaningful name.
- Description: Provide a brief description of what your app does and how it interacts with Smartsheet.
- Redirect URL: Enter the redirect URL for your app. This is where users will be redirected after they authorize your app to access their Smartsheet data.
- App URL: The URL where your app is hosted. This ensures that Smartsheet can communicate with your app.

Step 3: Obtain client ID and a client secret
Click "Save" and Smartsheet will assign the app a client ID and a client secret, which is needed for obtaining OAuth tokens for accessing Smartsheet API.

Step 4: Use Apidog to Obtain the OAuth Access Tokens
While you can get the OAuth access token by following the Smartsheet document, there is an easier method that requires minimal coding—using a powerful API development tool, Apidog, to get the OAuth token. Here is a step-by-step guide on how to do it:
First, download Apidog and open a new project. Click "New Endpoint" to create a new endpoint.

Secondly, on the newly created endpoint page, find and click on"Auth", then choose the auth type. In this case, choose OAuth 2.0 as required by Smartsheet.

In the pop-up form, fill in the information needed to get the Smarsheet API tokens according to the official document.

Click on "Get Token" at the bottom of the form. If successful, a pop-up window will appear, prompting you to sign in to your Smartsheet Developer account.

Once your identity is verified, the token will be granted and displayed in Apidog.

The generated Token will be automatically attached to the Authorization Header
, prefixed with Bearer
when you send an API request with Apidog. Get more detailed information at Apidog's help center: OAuth 2.0.
Step 5: Make a Smartsheet API Request with Apidog
Now that you have obtained the Smartsheet API token, it's time to make an API request. First, choose the API request method and enter the API path in the corresponding blank. The body parameters will be automatically filled according to the API path, so you don't need to enter them manually. Additionally, you don't need to manually copy the tokens; Apidog will automatically add the token to the Authorization Header
with the Bearer
prefix when you send any Smartsheet API request. The only remaining step is to click "Send" next to the blank, and you will immediately receive the API response in the "Response" section.
