Smartthings Rate Limits

SmartThings publishes per-endpoint rate limits and platform "guardrails" (hard resource caps). Limits are applied per authenticated principal / per installed app and, for device operations, per device. Every response carries X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset headers. Exceeding a rate limit returns HTTP 429 (Too Many Requests); exceeding a guardrail (a hard cap such as max subscriptions per app) returns HTTP 422 (Unprocessable Entity). Values below are drawn from the public rate-limits documentation and are approximate; confirm current numbers before relying on them.

Smartthings Rate Limits is the machine-readable rate-limit profile for Samsung SmartThings on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 17 rate-limit definitions, measuring requests, devices, subscriptions, schedules, and rules.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled and guardrail.

Tagged areas include Smart Home, IoT, Home Automation, Rate Limiting, and Quotas.

Policies

Rate Limit Response
Requests exceeding a rate limit receive HTTP 429 (Too Many Requests).
Guardrail Response
Requests that would exceed a hard resource cap (guardrail) receive HTTP 422 (Unprocessable Entity).
Backoff Strategy
Clients should read the X-RateLimit-Reset header and implement exponential backoff with jitter on 429 responses.
