Test vs live keys
Key prefixes
| Prefix | Delivery |
|---|---|
xrl_dev_… | Sink only — stored, events simulated, not delivered to public MX |
xrl_prd_… | Production MTA delivery |
When to use each
- Test — local dev, CI, QA of templates and webhooks
- Live — production application servers only
CI & staging
Inject XUREL_API_KEY=xrl_dev_… as a secret. Webhook test events work the same way
with test keys so you can assert signature verification in pipelines.
