I am receiving a 500 Internal Server Error in the Visa Direct multipullfundstransaction call. It's all setup and I have been sending requests to the API and pushed through all the setup issues on my end until I got to this one with no information.
The docs say to "Contact your Visa production support contact for investigation and assistance."
We don't have support contact (but really need one) as we are going to production soon.
As you have mentioned that you have figured it out the issue at our developers email, please run more test and let us know if you have any questions or issues.
