There was an error, but FirstData didn't send back an error message.

It this on a local dev environment?

This is where the form is set:

https://www.aem-laredo.org/donaciones-y-membresias/

Now the message is Invalid credit card number.

Just can′t make it work,

“There was an error, but FirstData didn’t send back an error message.” usually happens when FirstData can’t communicate with your site for some reason.

FirstData also recently updated their API to v12 and we use v11 and they are slowly phasing it out and you may have been hit. I have future plans to fix this when I am able.

First Data answered this:

You can determine which version of the WSDL you are using by checking where you are submitting payment. If you are submitting to “/transaction”, you are using version 8. If you are using any other version, your submission URL would be “/transaction/v” followed immediately by the version you are using (ie. “/transaction/v11” for Version 11”).

Then this shall work, yet is doesn′t, any new ideas?

Thanks!

I am having the very same problem. I’m not in a local dev either, and yes, I am collecting credit card information. I double-checked the credentials and the feed settings. Not sure what else to try.
The weird part is that FirstData can communicate with my website when I use one of their generated buttons my my site, but that does not offer all the fields that I need (suggested amounts, for example). I sure hope you can help us with this!

This might be due to any one of the issues on https://github.com/aubreypwd/gravityforms-firstdata/issues
