Please review the Visa Direct documentation via this link. https://developer.visa.com/capabilities/visa_direct/docs
In particular, see the top few paragraphs that are shaded in yellow 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. Please let us know if you have other questions.
Regarding the Outbound configurations:
1. Outbound callback is for mVisa (Merchant Payment “MP”, Cash-in and Cash-out) not Visa Direct (Fund Transfer “PP”)
2. If the client wants to implement the receive side then they will need to use the outbound callback:
3. In that case, Visa will call this API to request client to receive and process the payment transaction sent by the Sending institution.
