Repair API For Payment Gateway

A developer wrote an API for us, between one of our databases and a lodging site. He made mistakes with the API, and the payment functionality is not working. After a credit card is entered, and "Order" is hit, an error message appears.

This needs to be resolved, as well as a pop up box showing the no cancellation, no refund, etc policy. In addition, the text and links on the confirmation page must be changed.

You must have had experience working with payment API's, like [login to view URL] or Plugnpay. The job is not that complex but experience with online payment systems will be a big plus.

Note that the price shown is just a placeholder. We can discuss the price.

We want to work with an individual developer, not a company or an agency or someone associated with an agency.

Please start your proposal with the word "butterfly", so I know you read our requirements and this is not a spam response.

Thanks for the interest.

Skills: Javascript, MySQL, PHP, RESTful
