Australia Post Rate Limits

Australia Post rate-limits all API endpoints to maintain fair and consistent service across all developers. Limits are applied per credential and can be set on any combination of requests per second, minute, hour, or day depending on the individual API. Specific numeric thresholds are not published publicly and vary per API; exceeding any limit returns HTTP 429. Current consumption is surfaced in standard X-RateLimit-* response headers so clients can implement adaptive back-off.

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

It captures 4 rate-limit definitions, measuring requests_per_second, requests_per_minute, requests_per_hour, and requests_per_day.

The profile also includes 5 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Rate Limiting, Logistics / Shipping, and Postal.

Policies

Per-credential throttling
Rate limits are applied to the credentials (API key or OAuth token) used to make requests, not the developer account as a whole. Each app and its credentials have independent quotas.
HTTP 429 on breach
When any rate limit is exceeded all subsequent requests using that credential return HTTP 429 Too Many Requests until the limit window resets.
Adaptive back-off recommended
Clients should monitor X-RateLimit-Remaining-* headers and implement exponential back-off when approaching or hitting limits.
Per-API limits
Each Australia Post API (PAC, Locations, Shipping and Tracking, Delivery Choices, Delivery Partner) may have different rate limit windows and thresholds. Consult the individual API documentation for the applicable limits.
Contact for quota increases
If existing limits are insufficient for production workloads, contact Australia Post via customer_connectivity@auspost.com.au or speak with your account manager to request higher quotas.
