Connecting to Dropbox

Connecting to Dropbox

Dropbox uses the OAuth authentication standard.

Dropbox OAuth Scopes

You need to choose between using CData's embedded OAuth app or Create a Custom OAuth App.

Headless Machines

To configure the driver, use OAuth with a user account on a headless machine. You need to authenticate on another device that has an internet browser.

  1. Choose one of two options:
    • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
    • Option 2: Install the adapter on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow.
  2. Then configure the adapter to automatically refresh the access token on the headless machine.

Option 1: Obtain and Exchange a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL.

Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.

  1. Choose one of these options:
    • If you are using the Embedded OAuth Application, call the GetOAuthAuthorizationURL stored procedure. Open the URL returned by the stored procedure in a browser.
    • If you are using a custom OAuth application, set the following properties:
      • InitiateOAuth: Set to OFF.
      • OAuthClientId: Set this to the noted App key value from your OAuth app settings.
      • OAuthClientSecret: Set this to the App secret from your OAuth app settings.
      Then call the GetOAuthAuthorizationURL stored procedure with the appropriate CallbackURL. Open the URL returned by the stored procedure in a browser.
  2. Log in and grant permissions to the adapter. You are then redirected to the redirect URI. There will be a parameter called code appended to the redirect URI. Note the value of this parameter. Later you will set this in the OAuthVerifier connection property.
Next, you need to exchange the OAuth verifier code for OAuth refresh and access tokens.

On the headless machine, set the following connection properties to obtain the OAuth authentication values:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthVerifier: Set this to the noted verifier code (the value of the code parameter in the redirect URI).
  • OAuthClientId: (custom applications only) Set this to the noted App key value from your OAuth app settings.
  • OAuthClientSecret: (custom applications only) Set this to the App secret from your OAuth app settings.
  • OAuthSettingsLocation: Set this to persist the encrypted OAuth authentication values to the specified file.

Test the connection to generate the OAuth settings file, then re-set the following properties to connect:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthClientId: (custom applications only) Set this to the noted App key value from your OAuth app settings.
  • OAuthClientSecret: (custom applications only) Set this to the App secret from your OAuth app settings.
  • OAuthSettingsLocation: Set this to the file containing the encrypted OAuth authentication values. Make sure this file gives read and write permissions to the adapter to enable the automatic refreshing of the access token.

Option 2: Transfer OAuth Settings

Prior to connecting on a headless machine, you need to install and create a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the path specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.

Test the connection to generate the OAuth settings file, then copy the OAuth settings file to your headless machine.

On the headless machine, set the following connection properties to connect to data:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthClientId: (custom applications only) Set this to the noted App key value from your OAuth app settings.
  • OAuthClientSecret: (custom applications only) Set this to the App secret from your OAuth app settings.
  • OAuthSettingsLocation: Set this to the path to the OAuth settings file you copied from the machine with the browser. Make sure this file gives read and write permissions to the adapter to enable the automatic refreshing of the access token.
