New: Application API docs
Pick the API you are reading here — the Merchant API for your own store, the Application API for partner apps.
For partner applications: browse merchants and products, hand customers a checkout link, and follow the orders it creates.
Caching, rate limits and secret rotation — what to plan around once your integration is live.
| Topic | What to know |
|---|---|
| Caching | Categories, subcategories and locations are cached server-side; catalogue changes can take a few minutes to appear. |
| Rate limits | No per-application limit is enforced today. Do not build on that — back off on any 429. |
| Rotating secrets | When your app_secret is rotated, requests signed with the old one fail immediately, and webhooks are signed with the new one. Plan deployments accordingly. |
