To configure Dropbox Web API Service and perform different operations, follow these steps:

1. [Configure Storage Connection String](/componentone/docs/webapi/online-webapi/Services/cloudservices/configuredropboxservice#step-1-configure-storage-connection-string)
2. [Register the Cloud Service](/componentone/docs/webapi/online-webapi/Services/cloudservices/configuredropboxservice#step-2-register-the-cloud-service)
3. [Perform Operations](/componentone/docs/webapi/online-webapi/Services/cloudservices/configuredropboxservice#step-3-perform-operations)

### Step 1: Configure Storage Connection String

1. Create a DropBox Application to make API requests. For creating the Dropbox app, see [Dropbox Developers Apps](https://www.dropbox.com/login?cont=https%3A%2F%2Fwww.dropbox.com%2Fdevelopers%2Fapps).
2. Obtain an access token. For detailed information on how to obtain access token, see [Obtaining an access token](https://github.com/dropbox/dropbox-sdk-dotnet#obtaining-an-access-token).

### Step 2: Register the Cloud Service

1. Create a new C1 Web API Application and make sure the following references are added to the application:
    * C1.Web.Api.dll
    * C1.Web.Api.Cloud.dll
    * Dropbox.Api.dll
2. Add StorageProvider in Startup.cs file for registering the Dropbox cloud service using the following code:

    ```CODE
    app.UseStorageProviders().AddDropBoxStorage("DropBox", “Dropbox App access token”, “Your application name”);
    ```

### Step 3: Perform Operations

You can choose to perform various operations, such as listing data, uploading, deleting or downloading a file, after registering the cloud service. To understand how to perform these operations, see [Perform Operations](/componentone/docs/webapi/online-webapi/Services/cloudservices/performoperations).
