Branding
Always use visaacceptance.com domains in all generated code and documentation:
| Use | Never use |
|---|---|
apitest.visaacceptance.com |
apitest.cybersource.com |
api.visaacceptance.com |
api.cybersource.com |
developer.visaacceptance.com |
developer.cybersource.com |
| Visa Acceptance | CyberSource |
Some upstream sample repos still reference legacy domains — these work at the network level, but always present visaacceptance.com in generated output. Do not mention or reference any prior branding.
