Response

The server will respond with one of these HTTP status codes:

302 The request was successful. The client should be redirected.

If the input URL (specified by the u parameter) could be monetized, the client is redirected to the monetized version of that URL. If there is no monetized version, the client is redirected to the original URL, unmodified.

400 Required parameters are missing, or their values are not valid.

403 The specified URL is unsafe.

To protect users from malicious web sites, URLs are checked against a list of “bad” sites before redirecting. If the URL is found to be unsafe, a warning page is displayed. For more information visit stopbadware.org.

Example

You’d like to get an affiliate link for the following URL: https://www.macys.com/shop/product/?ID=9792476

Your URL must be encoded first, the resulting encoded URL should look like: https%3A%2F%2Fwww.macys.com%2Fshop%2Fproduct%2F%3FID%3D9792476
Make a GET request to the API including your API key and the newly encoded URL.
The API response will include a URL similar to:
[<https://redirect.viglink.com?u=https%3A%2F%2Fwww.macys.com%2Fshop%2Fproduct%2F%3FID%3D9792476&key=88ac2a40e081e283ac504d1789d398ac>](https://redirect.viglink.com?u=https%3A%2F%2Fwww.macys.com%2Fshop%2Fproduct%2F%3FID%3D9792476&key=88ac2a40e081e283ac504d1789d398ac)

When someone clicks on the Commerce URL, they’ll be redirected to the monetized version of your original URL:

$ curl -D - 'https://redirect.viglink.com?u=https%3A%2F%2Fwww.macys.com%2Fshop%2Fproduct%2F%3FID%3D9792476&key=88ac2a40e081e283ac504d1789d398ac'
