What is a Rule?
A rule defines how many requests are allowed for a specific action within a time window. Rules are scoped to a single project.
Creating a Rule
- Open your project from the Projects page
- Click the Rules tab
- Click New Rule
- Fill in the form:
| Field | Description | Example |
|---|
| Name | Unique identifier, used in SDK | send_email |
| Limit | Max requests per window | 10 |
| Window | Duration in seconds | 3600 (= 1 hour) |
| Algorithm | Fixed or Sliding Window | FIXED_WINDOW |
- Click Create — the rule is live immediately.
Use descriptive, snake_case names for rules. Your developers will use this string directly in code: limiter.check({ rule: "send_email" }).
Editing a Rule
Click the edit icon (pencil) on any rule card to update its limit, window, or algorithm. The rule name cannot be changed — if you need a new name, delete and recreate it.
Deleting a Rule
Click the delete icon (trash) on a rule card. A two-tap confirmation is required to prevent accidental deletions.
Deleting a rule will stop all enforcement for that rule name. Existing SDK calls for this rule will fail with an error.
Searching Rules
Use the search bar at the top of the Rules tab to filter rules by name.
