Tried geting help from the PayPal forum but never any answer and no answer in their docs that help so trying to get help here.
We use a custom ColdFusion shopping cart for our ecommerce site. The PayPal form we use works fine for our live, actual payment to PayPal. However, when we add the sandbox part of the URL for testing, we receive the ever present following error message from PayPal: “PayPal cannot process this transaction because of a problem with the seller's website. Please contact the seller directly to resolve this problem.”
I have both the personal and business accounts set up on the developer sites and am using the business account on sandbox form.. That seemed to go okay But that’s as far as I got. Once that was done there was no guide I could find to suggest what to do next. I’ve checked my developer account activity and history and there is none.
I continue to get this error also: “We’re sorry, but something went wrong. Please try again.” It’s at this URL: https://developer.paypal.com/webapps/developer/applications/myapps
paypal sandbox merchant account error
At the URL above, the forum suggestion stated: “ .. click the link for sandbox accounts on the left” of the Applications Tab. But there is nothing there indicating “sandbox account” on the left side or anywhere.
I’d really like to see an example of a sandbox paypal form where the cost is set to a variable, and in our case we use a cfquery output variable.
I guess I need to “create a preconfigured test seller account.” But where? How? Just a big circle on the PayPal developer site.
I’ve read other examples from others here in their forum but the suggestions don’t always seem to match up with the actual page, perhaps PayPay developer site has changed and the url is obsolete at best.
Obviously, everything else is working so we have the correct setup to charge but something must be wrong with the sandbox account. We have both business and personal accounts set up but the error remains. I’ve spent two hours researching but cannot find a clue to what the problem may be. The massive amount of data on PayPal is no help I’ve yet been able to find.
We’d use the standard Buy Now buttons but they have built in payment amounts. Our payment amounts change dynamically so we need to use a variable in the form of the payment amount so that’s why we decided to use a custom form.
Would like someone to explain what may be the problem on the sandbox setup, or go thrugh the stages what needs to be done once the business and personal accounts are defined, then maybe point me to an example of what the basic html form looks like and the requirements of that form (allowing custom price amounts based on a variable amount) to send to PayPal sandbox.
