To aid in the development process, TokenEx has enabled an echo endpoint to allow you to test Detokenization before sending the request to the gateway test server. To enable echo mode for your request, simply append the querystring "?test=true" to the URL (i.e. for Detokenize).

If this process is successful, the value "***SUCCESS***" will appear in place of the token(see Error Handling). Once the request has been tested successfully, simply remove the querystring "?test=true" from the URL.

Approved Hosts

Before you begin using the Transparent Gateway API, you need to check to see if TokenEx has allowed communication with the desired host. This is accomplished by making a GET request to to obtain a list of the approved hosts.


If the remote API's host name is not in the list, please open a support ticket in our Customer Portal to have it added.
