Dropbox SDK for Go [UNOFFICIAL]

An UNOFFICIAL Go SDK for integrating with the Dropbox API v2. Tested with Go 1.5+

Warning

This SDK is NOT yet official. What does this mean?

There is no formal Dropbox support for this SDK at this point
Bugs may or may not get fixed
Not all SDK features may be implemented and implemented features may be buggy or incorrect

Uh OK, so why are you releasing this?

the SDK, while unofficial, is usable. See dbxcli for an example application built using the SDK
we would like to get feedback from the community and evaluate the level of interest/enthusiasm before investing into official supporting one more SDK

Installation

$ go get github.com/dropbox/dropbox-sdk-go-unofficial

Note that while the import path ends in dropbox-sdk-go-unofficial, it actually exports the package dropbox. There are additional subpackages, one for each namespace in the API:

github.com/dropbox/dropbox-sdk-go-unofficial/users
github.com/dropbox/dropbox-sdk-go-unofficial/files
github.com/dropbox/dropbox-sdk-go-unofficial/sharing
github.com/dropbox/dropbox-sdk-go-unofficial/team

Usage

First, you need to register a new "app" to start making API requests. Once you have created an app, you can either use the SDK via an access token (useful for testing) or via the regular OAuth2 flow (recommended for production).

Using OAuth token

Once you’ve created an app, you can get an access token from the app’s console. Note that this token will only work for the Dropbox account the token is associated with.

// NOTE: this imports package `dropbox`
import "github.com/dropbox/dropbox-sdk-go-unofficial"

func main() {
  api := dropbox.Client(token, dropbox.Options{Verbose: true}) // second argument enables verbose logging in the SDK
  // start making API calls
}

Using OAuth2 flow

For this, you will need your APP_KEY and APP_SECRET from the developers console. Your app will then have to take users though the oauth flow, as part of which users will explicitly grant permissions to your app. At the end of this process, users will get a token that the app can then use for subsequent authentication. See this for an example of oauth2 flow in Go.

Once you have the token, usage is same as above.

Making API calls

Each Dropbox API takes in a request type and returns a response type. For instance, /users/get_account takes as input a GetAccountArg and returns a BasicAccount. The typical pattern for making API calls is:

Instantiate the argument via the New* convenience functions in the SDK
Invoke the API
Process the response (or handle error, as below)

Here’s an example:

  arg := users.NewGetAccountArg()
  if resp, err := api.GetAccount(arg); err != nil {
    return err
  }
  fmt.Printf("Name: %v", resp.Name)

Error Handling

As described in the API docs, all HTTP errors except 409 are returned as-is to the client (with a helpful text message where possible). In case of a 409, the SDK will return an endpoint-specific error as described in the API. This will be made available as EndpointError member in the error.

Note on using the Teams API

All features of the Team API are supported except acting on behalf of team members. This should be available soon.

Note that to use the Team API, you will need to create a Dropbox Business App. The OAuth token from this app will only work for the Team API.

Please read the API docs carefully to appropriate secure your apps and tokens when using the Team API.

Caveats

To re-iterate, this is an UNOFFICIAL SDK and thus has no official support from Dropbox
Only supports the v2 API. Parts of the v2 API are still in beta, and thus subject to change
This SDK itself is in beta, and so interfaces may change at any point
