Cdw Rate Limits

CDW's Catalog API and eProcurement integration surfaces are gated behind a B2B customer account; rate-limit documentation is not published on the public eprocurement-and-custom-catalogs page. Limits are negotiated with the CDW eProcurement / integration team during onboarding and align with the customer's expected order volume.

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

It captures 3 rate-limit definitions, measuring varies.

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 3 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include eProcurement, Catalog, PunchOut, and Rate Limiting.

PunchOut session lifecycle
PunchOut sessions are short-lived and tied to a buyer system's outbound URL; sessions expire after a documented inactivity window.
