1. What is the VAU Merchant Enrollment API?
The VAU Merchant Enrollment API is a secure, scalable, and high-performance web service/API for Acquirers to automate their VAU merchant enrollment process. The VAU Merchant Enrollment API automates the merchant enrollment process in real time when all the required information is provided and considerably saves several days in enrollment using the existing process.
2. How does VAU Merchant Enrollment API work?
The VAU Merchant Enrollment API takes as input either a single or multiple merchants (max: 100) in one call eliminating the need to call repeatedly to enroll merchants in real time for US merchants and non-US merchants except in those cases where additional research is required by the compliance department.
3. Does this API replace another existing VAU process?
No, this API is not meant to replace the existing VAU Merchant Enrollment Excel file. It is an optional additional channel added to automate the merchant enrollment process in real time saving several days and enabling immediate enrollment so the merchant can start benefiting from use of VAU right away.
4. Is the API available globally?
The API is available in regions/countries where VAU is available.
5. If I am supporting multiple acquirers, can I use the VAU Merchant Enrollment API?
Yes. Please note that separate registration is required for each acquirer, as each acquirer has their own unique Visa Business ID and associated VAU segment IDs..
6. What are the features of the VAU Merchant Enrollment API?
7. What are the responses of the VAU Merchant Enrollment API?
If the VAU Merchant Enrollment API request call is successful, the API would return the following outcomes:
Success -- when the merchant(s) are successfully enrolled.
In-Progress – when the merchant(s) enrollment is not complete and requires additional research.
-- To check for updated status of merchants where “in-progress” response was provided to initial enrollment, please use VAU Merchant Search API.
Reject – This happens either when merchant(s) did not qualify for compliance check, or, when required fields are missing.
A rejected message is also provided in the response.
8. How can an acquirer get status updates on whether a merchant was previously enrolled?
The VAU Merchant Search API is a secure, scalable, and high-performance web service/API for Acquirers to check the updated status for those merchants where initial response to enrollment was “In-progress”. This API can also be used to check the enrollment status of any merchants previously enrolled or submitted for enrollment by the acquirer. For more information, please refer to VAU Merchant Search API FAQs.
9. What fields are required to be included for the VAU merchant enrollment API?
To ensure successful merchant enrollment and to avoid potential delays due to insufficient information, Visa highly recommends that clients should provide values for the optional fields to avoid false positives during the screening process and increase the chance of successful merchant enrollment.
10. If I have multiple CAIDs, which one should I use?
We recommend that the mostly used CAID be used in the API request.
11. If I have multiple MCCs, which one should I use?

Acquirers are strictly advised not to use pipe “|” in merchant name.
14. If I already have a project created on VDC and using other APIs, do I need to create a new project and add the Merchant Enrollment API?
No. If you have a project created, you can re-use the project and select ‘Add API’ link and add VAU Merchant Enrollment API from the project dashboard.
