How do I add MD5 Hash to my payment form for Authorize.net

How do I add  MD5 Hash to my payment form for Authorize.net

With our current Authorize.net integration, you won't need to add an MD5 Hash. All we require from you to complete the Integration would be your API Login ID and Transaction Key.

In case we misunderstood your question, just get back to us with a bit more info and a clearer description of what you're trying to do so we can better assist you.

I have to use MD5 Hash, thus I'm asking asking how to enter it... in the jotform...

I understand you're using the MD5 Hash security feature of Authorize.net but there's no option within JotForm where you can add it.

Just to confirm though, does it cause any trouble if you're not able to add the MD5 Hash? Are the API Login ID and Transaction Key not working on their own without the hash? If that's the case, can you share with us the form you're currently working on where you're seeing this problem?

Otherwise, if you're only confirming if there's a way to add your MD5 Hash in JotForm, then I'm afraid there's no option to do that atm.
