Payjp Rate Limits

PAY.JP enforces per-second request rate limits split into three zones by key type and operation. Token creation (publishable-key "pk" zone), payment operations such as charges and refunds ("payment" zone), and other secret-key requests ("sk" zone) each have their own thresholds, with much lower limits in test mode. Exceeding a limit returns HTTP 429 with the over_capacity error code.

Payjp Rate Limits is the machine-readable rate-limit profile for PAY.JP on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, measuring requests_per_second.

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled and errorCode.

Tagged areas include Payments, FinTech, Japan, Rate Limiting, and Quotas.
