# VelocityDimensionLimits

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

Velocity limits counted separately for each value of one dimension, such as each cardholder IP
address. Windows behave exactly as the merchant-wide limits on `VelocitySettings`.
