Prepare a Callback (back to all tutorials)

Most Veriplace API calls use the OAuth redirect and callback process. Before your application can make these calls, it must specify a URL for this callback.

1. Option 1: Hardcode a Callback

   The simplest approach is to hardcode your callback to a fixed URL:

2. Option 2: Determine Callback from HttpServletRequest

   In many cases, you will want to generate a callback that refers back to the same server (host and port) that initiated the request. The SDK offers any easy way to construct such a callback from an HttpServletRequest:

   The boolean argument in this example controls whether the callback includes path information from the request; you can override this and other callback behavior by using the com.veriplace.client.factory.DefaultCallbackFactory directly:

3. Option 3: Define a CallbackFactory

   If you wish to configure a callback through some other mechanism, you can implement your own version of com.veriplace.client.factory.CallbackFactory. This is particularly useful in conjuction with the Verplace web framework.
