Integrate CCBill API Into Single Webpage using Wix

I need to integrate CCBill Flexform API into a single webpage, passing in a variable from URL querystring, into code within the page to generate MD5 hash and then invoke the CCbill API into the iFrame within the page. FROM CCBILL SUPPORT: https://kb.ccbill.com/Dynamic+Pricing Also, please find below link for md5 Hash generator: [login to view URL] I will include an explanation from our knowledge base regarding GENERATING THE MD5 HASH along with code examples: The formDigest value is a hex-encoded MD5 hash, calculated using a combination of the above fields and a salt value. More information can be found about salt cryptography here. CCBill uses your salt value to verify the hash and can be obtained in one of two ways: Contact merchant support and receive the salt value, OR Create your own salt value (up to 24 alphanumeric characters) and provide it to Merchant Support. Using your preferred MD5 hash generation tool and the Hex encoding method, you will need to create an MD5 Hex Digest using certain variable values. Values should be concatenated into one single string with no spaces prior to hashing. For single billing transactions, use the following values in the order they are listed: initialPrice initialPeriod currencyCode salt For recurring transactions, use the following values in the order they are listed: initialPrice initialPeriod recurringPrice recurringPeriod numRebills currencyCode salt The resulting MD5 hash will be used as the value for the formDigest variable. This value can be statically hard-coded into a page or generated “on the fly” using a custom script.
