EmitHQ commits to the following monthly uptime percentages for the webhook delivery API:
| Tier | Uptime SLA | Max Downtime/Month |
|---|---|---|
| Free | No SLA | — |
| Starter ($49/mo) | 99.9% | ~43 minutes |
| Growth ($149/mo) | 99.95% | ~22 minutes |
| Scale ($349/mo) | 99.99% | ~4 minutes |
“Uptime” means the webhook delivery API (POST /api/v1/app/:appId/msg) is accepting and processing requests. The dashboard and documentation site are not covered by this SLA.
If monthly uptime falls below the committed SLA, you are eligible for service credits applied to your next invoice:
| Monthly Uptime | Credit |
|---|---|
| < 99.9% but ≥ 99.0% | 10% of monthly fee |
| < 99.0% | 25% of monthly fee |
Credits are capped at 30% of your monthly fee. Credits are issued as account balance adjustments, not cash refunds. Credits must be requested within 30 days of the incident.
The following are excluded from uptime calculations:
Uptime is measured using external monitoring (synthetic health checks every 60 seconds from multiple geographic locations). A “downtime minute” is recorded when two or more monitoring locations fail to receive a successful response.
Monthly uptime percentage = (total minutes in month − downtime minutes) / total minutes in month × 100.
To claim a service credit:
In addition to API uptime, we target the following delivery performance metrics on a best-effort basis (not credit-eligible):
These targets exclude endpoint-side failures (timeouts, 5xx responses from your customers' endpoints).
