Fraud Protection

Custom forms are not protected by Click & Pledge's fraud protection guarantee since reCAPTCHA cannot be enforced, as well as various server-side checks & balances we have included in the CONNECT forms.  Please make sure the forms are tested against credit card validation robo-attacks.  By using the API you are accepting complete responsibility for all fraudulent transactions.


Click & Pledge’s Payment Application Interface (PAI) provides a comprehensive API for the Trio payment and administrative engine. Through the PAI, programmers may interact with the Trio system within their respective applications. To prevent spam and fraudulent attacks on webforms that use Click & Pledge’s API all forms must include reCAPTCHA to validate patrons.

By default all accounts are set up with the API credentials. To access the API information follow the steps listed below:

Make sure to check the sample code section as well as the Sandbox for testing the XML’s generated by your code. [Check the table of content for links].
