Swipe the table sideways to see every column.
| Limit | Default | What happens |
|---|---|---|
| Runs per end user per day | 20 | Over it: 429 end_user_cap_reached with Retry-After (resets 00:00 UTC). Your org can change its cap. |
| Runs at once per product | 20 | More runs wait in line (queued), up to as many again; past that a Priority run gets 429 product_busy with Retry-After (about 5 s) and no run is created. Slower-lane runs always wait. Priority goes first. Set per product; it rises when provider quotas rise. |
| Active Relax runs per end user | 1 | The next Relax run of that end user starts when the last one ends. |
| Webhook signature window | 300 s | Reject a webhook whose timestamp is older or newer than this. |
