| `twilio-verify-service` | `NTFY_TWILIO_VERIFY_SERVICE` | *string* | - | Twilio Verify service SID, e.g. VA12345beefbeef67890beefbeef122586 |
| `keepalive-interval` | `NTFY_KEEPALIVE_INTERVAL` | *duration* | 45s | Interval in which keepalive messages are sent to the client. This is to prevent intermediaries closing the connection for inactivity. Note that the Android app has a hardcoded timeout at 77s, so it should be less than that. |
| `manager-interval` | `NTFY_MANAGER_INTERVAL` | *duration* | 1m | Interval in which the manager prunes old messages, deletes topics and prints the stats. |
| `message-poll-limit` | `NTFY_MESSAGE_POLL_LIMIT` | *number* | *(uncapped)* | Max number of cached messages returned per topic when the cache is replayed (a poll, or a `since` request). A poll without a `since` cursor returns a topic's entire cache, which is unbounded in size. When set, the newest messages are kept and the response carries an `X-Messages-Truncated: 1` header. Together with `message-size-limit` this bounds the memory one replay can allocate. |
| `message-size-limit` | `NTFY_MESSAGE_SIZE_LIMIT` | *size* | 4K | The size limit for the message body. Please note that this is largely untested, and that FCM/APNS have limits around 4KB. If you increase this size limit, FCM and APNS will NOT work for large messages. |
| `message-delay-limit` | `NTFY_MESSAGE_DELAY_LIMIT` | *duration* | 3d | Amount of time a message can be [scheduled](publish.md#scheduled-delivery) into the future when using the `Delay` header |
| `global-topic-limit` | `NTFY_GLOBAL_TOPIC_LIMIT` | *number* | 15,000 | Rate limiting: Total number of topics before the server rejects new topics. |
