The Visa B2B Connect APIs can be used in the sanbox by any developer with a registration and upon acceptance of terms and conditions. The sandbox does not have Visa network connectivity, so validating the receipt of a pull funds, push funds, or reverse funds transfer cannot occur in the sandbox.
You can use the API explorer provided in the API Reference section to understand the usage of the APIs in the Sandbox.
