A mechanism that restricts the number of API requests or messages processed within a specified time to prevent overload or abuse.
Why Rate Limiting Matters
Without a limit, a single misbehaving script, a runaway loop, a compromised API key, could flood a route or an account's API access far beyond what it was provisioned for, degrading service for everyone sharing that infrastructure. Rate limiting exists to cap that blast radius per account or per key.
How Rate Limiting Works
Requests or message submissions are counted against a configured ceiling, typically requests per second or messages per second, per account or API key. Traffic beyond that ceiling within the window is queued, delayed, or rejected depending on how the limit is configured.
How SMPPCenter Uses This
SMPPCenter enforces rate limits per account and per API key independently of the underlying route's own TPS ceiling, so one account's traffic spike cannot consume capacity that was provisioned for another account on the same platform.
