Limits
The default global limit is 200 requests per 60 seconds. The Thank You promo read uses a higher limit so a store can serve a sale without sharing one tight bucket across every shopper:
That Thank You limit is about 50 requests per second from one IP. It covers a large store’s checkout burst, or a platform node calling the API for many brands, when those calls leave through the same address. Cache the response briefly on your side when you can. The offer changes rarely, and a short cache avoids one upstream call per shopper.
When you exceed a limit
We respond with HTTP 429 and an OpenAPI error body:Working within the limits
Retry later after you receive a429. Space requests across the 60-second window when you poll or backfill.
If these limits are too tight for a legitimate integration, contact support.
