Smile Io Rate Limits

Smile.io documents a fixed per-token request-rate limit for its REST API: up to 10 requests per second per token. When the limit is exceeded, further requests return HTTP 429 - Too Many Requests, and after one second has elapsed the token's limit resets and requests respond normally. Enterprise plans can negotiate custom API rate limits. Separately, plan-level monthly order allowances govern how much loyalty activity a program can process (with per-order overage), which is a billing quota rather than an API request limit.

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

It captures 3 rate-limit definitions, measuring requests and orders.

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

Tagged areas include Loyalty, Rewards, E-commerce, Rate Limiting, and Quotas.

Enterprise plans can negotiate custom API rate limits.
Monthly Order Allowance account
orders
per plan
Billing quota per plan tier (for example 200 / 500 / 1000 / 2500 / 7500), with per-order overage above the allowance. Not an API request limit.

Policies

Throttling
Requests beyond 10/second per token receive HTTP 429; the token limit resets after one second.
Backoff Strategy
Clients should implement exponential backoff with jitter and retry after the one-second reset window on 429 responses.
Request Reduction
Smile recommends caching responses and reducing request volume to stay within the per-second limit.
