Accept Hosted help with IFrame/Lightbox asp.net

I currently have a SIM style asp.net page that opens the old school Authorize.net hosted page.  Currently the page collects transaction details, then posts the collected information to the old Authorize.net hosted page via a single button click. I have been looking at the new Accept Hosted implementations and am trying to get the IFRAME/Lightbox up and running as it is the only scenario that appears to support custom reciepts and redirecting (we email our own receipt and redirect to a confirmation page).

 

So modifying the IFrame/Lightbox code shown on 

 

https://developer.authorize.net/api/reference/features/accept_hosted.html#Displaying_the_Form

 

I am able to obtain a token when the button is clicked, however, I have not been able to display the hosted form in the IFrame/Lightbox.  I obtain the token in the asp.net codebehind the page, but can't seem to pass it back out to the AuthorizeNetPopup.openPopup or alternately execute the AuthorizeNetPopup.openPopup script from the codebehind.

 

Basically, what I am wanting to do is obtain the token and display the accept hosted page in an IFrame/Lightbox with a single button click in an asp.net page and I can't seem to figure out how to make that happen, or if it is even possible.  Any thoughts/samples would be appreciated.

Re: Accept Hosted help with IFrame/Lightbox asp.net

[ Edited ]

Finally got this to work.  In the HTML code I removed the following lines:

 

$("#popupToken").val($("<% = thetoken %>").val());
form.action = "https://test.authorize.net/payment/payment";

and in the Sub PosttoProcessingCenter subroutine of the .aspx code behind I added:

 

ScriptManager.RegisterClientScriptBlock(Page, GetType(String), "Javascript", "AuthorizeNetPopup.openPopup(); return false;", True)

 just below the line:

thetoken = mymessage("token").ToString

@emlinney 

 

It should be doable. What you do is have your form API call programmed to execute with no button press.   As soon as the page loads, you will have a token. The customer then presses the button which submits that token as a POST request to get the form.

Again, I'm trying to develop a proof of concept for the page that I need to incorporate this into.  That page is just a form that donors to our foundation fill out noting how much they would like to donate. They would then click a button which should generate the token and display the credit card payment. page.

Re: Accept Hosted help with IFrame/Lightbox asp.net

And the codebehind page...there is extra code in here from stuff that I have tried which did not seem to work...hopefully someone will see something that can get me going in the right direction.  I can generate the token, but can't seem to display the accept hosted form in the lightbox.

Re: Accept Hosted help with IFrame/Lightbox asp.net

Thank you for the reply and the suggestion.  I'm just not sure how to do what you propose.  Our current form takes in an amount and uses the button click to initiate the "get token" process. It is at that point that I can't figure out how to launch the accept hosted form in an iframe/lightbox.

Re: Accept Hosted help with IFrame/Lightbox asp.net

Glad you found your solution. There are many ways to go about this. I am building an iframe integration right now and I have my token generated entirely with values that are pulled from the customers records in the database.

Interesting.  If you have some time, would you be able to briefly explain how you are doing that? I thought a token could only be generated if you had an amount to pass along to the API.

Re: Accept Hosted help with IFrame/Lightbox asp.net

@emlinney

That is correct. I have a Review Your Order page and then the next button click takes them to the iframe payment page. On the iframe payment page all of the customers info, including the products in their cart, are pulled from the dB and those are used to calculate the amount to make the api call. The api call is made by the server side code and JavaScript loads the iframe on load.
