How to pass the total payment value to a URL?

I'm trying to identify the field name for a variable amount that calculated in the payment wizard so I can return it to prefill a url please. I have attached a screenshot and here's a link to a test form.

Thanks

Chris

Dear Chris,

As I've understood your problem, you wanted to send the total payment value to another URL.

My recommendation is adding a Form Calculation widget to your form in order to get the total value of the Purchase Order as you can see the screenshot below:

Also, you can set this calculation field hidden not to let your users see it on the form.

Finally, you can post the total payment (as calculation field) to another URL as you can find in the following document: https://www.jotform.com/help/351-How-to-Automatically-Pass-Form-Data-to-Another-Form

As I have checked your form, you have redirected your thank you page to the following external link: https://pnpnet.qvalent.com/OnlinePaymentServlet?cd_community=SLSA&cd_currency=AUD&cd_supplier_business=519&CP_p1typeId=67&CP_p1desc=Australia%20Day&CP_p1amount={payment_total_checksum}

You can use the {calculation} field in order to prepopulate your field in your external link.

Moreover, please find the following document for further information related to sending submission data via Post Method: https://www.jotform.com/help/213-Send-Submission-Data-via-Post-Method-and-Thank-You-Settings

Thanks in advance.

Hi Candy,
