# UsageBudgetExceededResponse

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

The body a sandbox request is refused with when its merchant has spent the plan's transaction
allowance.

## Fields
- `error` (string) required: The refusal class. Always `TooManyRequests`. (nullable)
- `code` (string) required: The machine-readable refusal code. Always `USAGE_BUDGET_EXCEEDED`. (nullable)
- `message` (string) required: What ran out and what to do about it: when the allowance resets, or that it does not reset and  retrying won't help. (nullable)
- `limit` (integer(int64)) required: The number of sandbox transactions the plan allows in the window that refused.
- `used` (integer(int64)) required: The number already used in that window. Zero when the plan refuses sandbox transactions  outright, since nothing was spent.
