Airwallex Rate Limits

Published Airwallex API rate and concurrency limits. Airwallex enforces two distinct controls - a rate limit (requests over a rolling window) and a concurrency limit (in-flight requests) - at three levels: global (all endpoints for an account/org), endpoint (one operation across all resources), and resource (one specific resource id). The authentication endpoint is carved out with its own fixed limit.

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

It captures 8 rate-limit definitions, measuring requests_per_second, concurrent_requests, and requests_per_minute.

Limit state is signalled in the documented and note response headers, and an exhausted limit returns HTTP 429.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled and quotaExceeded.

Tagged areas include Cross-Border Payments, FinTech, Payments, Rate Limiting, and Throttling.

100
A separate fixed limit that does not follow the structure above and applies regardless of account or environment. Access tokens are valid for 30 minutes and are meant to be cached and reused; authenticating per request will exhaust this limit.
Resource-level limits resource
requests_per_second
Certain resources carry their own rate and concurrency limits on a single resource id (for example POST /api/v1/pa/payment_intents/{id}/confirm on one intent). Airwallex documents these per operation in the API Reference and publishes no global number, so this is recorded as present-but-unquantified rather than guessed.

Policies

Backoff strategy
On a 429, retry with exponential backoff plus random jitter - 1s, 2s, 4s, doubling to a ceiling of roughly 16s. Jitter is explicitly called for so clients do not synchronize retries.
Client-side throttling
For scheduled batch tasks and high-volume operations, implement client-side throttling to stay within the account and endpoint limits rather than relying on 429s.
Uplift
Higher production limits, including temporary uplifts for events such as a flash sale, are arranged through Airwallex support rather than self-serve.
Load testing
Airwallex discourages load testing in the sandbox - its lower limits and mock mechanisms produce misleading results. It recommends mocking the Airwallex API with production-measured latency instead.
