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".

Click "Create New App" to create a new app at Smartsheet

You will be directed to the app detailed page where you will be prompted to provide various details about your app, including:

  1. App Name: Give your app a meaningful name.
  2. Description: Provide a brief description of what your app does and how it interacts with Smartsheet.
  3. 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.
  4. App URL: The URL where your app is hosted. This ensures that Smartsheet can communicate with your app.
Fill detailed information about the created app in Smartsheet

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.

Create a new endpoint at Apidog

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.

Find and choose Auth type for obtaining API tokens

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

Fill in information needed to get Smartsheet API token at Apidog

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.

Get Smartsheet API token at Apidog by verifying identity

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.
