Application-Only Authentication Flow

Applications can use the client credentials grant type of the OAuth2 specification to get an access token that will provide access to public, non-user-specific data (events, listings, etc).

1. Create a Basic Authorization header

• URL encode your application's client id and client secret according to RFC 1738
• Concatenate the encoded client id, a colon character “:” and the encoded consumer secret into a single string
• Base64 encode the string from the previous step

2. Obtain an access token

• The value calculated in Step 1 must be exchanged for an access token:

Request

curl

curl -X POST "https://account.viagogo.com/oauth2/token"
  -u "clientId:clientSecret" --basic
  -H "Content-Type: application/x-www-form-urlencoded"
  -d "grant_type=client_credentials"
  -d "scope=read:events"

C#

var api = new ViagogoClient(
    "clientId",
    "clientSecret",
    new ProductHeaderValue("MyAwesomeApp"));
var token = await api.OAuth2.GetClientAccessTokenAsync(new[] {"read:events"});

Ruby

api = GogoKit::Client.new(client_id: CLIENT_ID, client_secret: CLIENT_SECRET)
token = api.get_client_access_token({scope: 'read:events'})
