Klarna Rate Limits

Klarna publishes per-second rate limits for its Global API Gateway, broken down by API operation category and enforced at two levels simultaneously — Partner and Acquiring Partner. The category that applies to a given call is stated in that operation's description in the API reference. Quota is enforced per data centre, so the same Partner calling from different regions can see different rate-limit state.

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

It captures 14 rate-limit definitions, measuring requests.

Limit state is signalled in the X-Ratelimit-Limit, X-Ratelimit-Remaining, and X-Ratelimit-Reset response headers, and an exhausted limit returns HTTP 429.

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

Tagged areas include Fintech, BNPL, Payments, Rate Limiting, and Quotas.

Policies

Backoff Strategy
Klarna requires exponential back-off with jitter on 429, and recommends a token-bucket algorithm on the caller side to shape global request flow.
Enforcement level
Limits are tracked simultaneously at Acquiring Partner level (all operations including sub-Partners) and Partner level. Hitting either limit rate-limits the request.
Change management
Rate-limit adjustments follow Klarna's versioning and deprecation process, but may change without notice in response to abuse. Klarna instructs integrators to read the response headers rather than hard-code the documented numbers.
