Hi,
Please review the Visa Direct documentation via this link - https://developer.visa.com/capabilities/visa_direct/docs
In order to use Visa Direct, all Visa Direct programs require the originator to be a licensed Visa acquirer or be sponsored by a licensed Visa acquirer who is ready and able to sponsor Visa Direct programs.
In particular, see the top few paragraphs that are shaded that discuss the requirements to use Visa Direct.
After having read the documentation, if you meet those requirements, then please click through the link in those paragraphs to the Visa Direct Program Implementation Questionnaire, fill it out, and submit to the email address listed on that form.
Thanks,
Jai
