+
+# Public facing base URL of the service (e.g. https://ntfy.sh or https://ntfy.example.com)
+#
+# This setting is required for any of the following features:
+# - attachments (to return a download URL)
+# - e-mail sending (for the topic URL in the email footer)
+# - iOS push notifications for self-hosted servers (to calculate the Firebase poll_request topic)
+# - Matrix Push Gateway (to validate that the pushkey is correct)
+#
+base-url: https://ntfy.pim.kunis.nl
+
+# Listen address for the HTTP & HTTPS web server. If "listen-https" is set, you must also
+# set "key-file" and "cert-file". Format: [<ip>]:<port>, e.g. "1.2.3.4:8080".
+#
+# To listen on all interfaces, you may omit the IP address, e.g. ":443".
+# To disable HTTP, set "listen-http" to "-".
+#
+# listen-http: ":80"
+# listen-https:
+
+# Listen on a Unix socket, e.g. /var/lib/ntfy/ntfy.sock
+# This can be useful to avoid port issues on local systems, and to simplify permissions.
+#
+# listen-unix: <socket-path>

+# This is optional and only required to save battery when using the Android app.
+#
+# firebase-key-file: <filename>
+
+# If "cache-file" is set, messages are cached in a local SQLite database instead of only in-memory.
+# This allows for service restarts without losing messages in support of the since= parameter.
+#
+# The "cache-duration" parameter defines the duration for which messages will be buffered
+# before they are deleted. This is required to support the "since=..." and "poll=1" parameter.
+# To disable the cache entirely (on-disk/in-memory), set "cache-duration" to 0.
+# The cache file is created automatically, provided that the correct permissions are set.
+#
+# The "cache-startup-queries" parameter allows you to run commands when the database is initialized,
+# e.g. to enable WAL mode (see https://phiresky.github.io/blog/2020/sqlite-performance-tuning/)).
+# Example:
+#    cache-startup-queries: |
+#       pragma journal_mode = WAL;
+#       pragma synchronous = normal;
+#       pragma temp_store = memory;
+#       pragma busy_timeout = 15000;
+#       vacuum;
+#
+# The "cache-batch-size" and "cache-batch-timeout" parameter allow enabling async batch writing

+# size, or after the given timeout. This is only required for high volume servers.

+#
+# Once enabled, a client may send a "Rate-Topics: <topic1>,<topic2>,..." header when subscribing to topics via
+# HTTP stream, or websockets, thereby registering itself as the "rate visitor", i.e. the visitor whose rate limits
+# to use when publishing on this topic. Note: Setting the rate visitor requires READ-WRITE permission on the topic.
+#
+# UnifiedPush only: If this setting is enabled, publishing to UnifiedPush topics will lead to a HTTP 507 response if
+# no "rate visitor" has been previously registered. This is to avoid burning the publisher's "visitor-message-daily-limit".
+#
+# visitor-subscriber-rate-limiting: false
+
+# Payments integration via Stripe
+#
+# - stripe-secret-key is the key used for the Stripe API communication. Setting this values
+#   enables payments in the ntfy web app (e.g. Upgrade dialog). See https://dashboard.stripe.com/apikeys.
+# - stripe-webhook-key is the key required to validate the authenticity of incoming webhooks from Stripe.
+#   Webhooks are essential up keep the local database in sync with the payment provider. See https://dashboard.stripe.com/webhooks.
+# - billing-contact is an email address or website displayed in the "Upgrade tier" dialog to let people reach

+# Metrics
+#
+# ntfy can expose Prometheus-style metrics via a /metrics endpoint, or on a dedicated listen IP/port.
+# Metrics may be considered sensitive information, so before you enable them, be sure you know what you are
+# doing, and/or secure access to the endpoint in your reverse proxy.
+#
+# - enable-metrics enables the /metrics endpoint for the default ntfy server (i.e. HTTP, HTTPS and/or Unix socket)
+# - metrics-listen-http exposes the metrics endpoint via a dedicated [IP]:port. If set, this option implicitly
+#   enables metrics as well, e.g. "10.0.1.1:9090" or ":9090"
+#
+# enable-metrics: false
+# metrics-listen-http:
+
+# Profiling
+#
+# ntfy can expose Go's net/http/pprof endpoints to support profiling of the ntfy server. If enabled, ntfy will listen
+# on a dedicated listen IP/port, which can be accessed via the web browser on http://<ip>:<port>/debug/pprof/.
+# This can be helpful to expose bottlenecks, and visualize call flows. See https://pkg.go.dev/net/http/pprof for details.
+#
+# profile-listen-http:
+
+# Logging options
+#
+# By default, ntfy logs to the console (stderr), with an "info" log level, and in a human-readable text format.
+# ntfy supports five different log levels, can also write to a file, log as JSON, and even supports granular
+# log level overrides for easier debugging. Some options (log-level and log-level-overrides) can be hot reloaded
+# by calling "kill -HUP $pid" or "systemctl reload ntfy".
+#
+# - log-format defines the output format, can be "text" (default) or "json"
+# - log-file is a filename to write logs to. If this is not set, ntfy logs to stderr.
+# - log-level defines the default log level, can be one of "trace", "debug", "info" (default), "warn" or "error".
+#   Be aware that "debug" (and particularly "trace") can be VERY CHATTY. Only turn them on briefly for debugging purposes.
+# - log-level-overrides lets you override the log level if certain fields match. This is incredibly powerful
+#   for debugging certain parts of the system (e.g. only the account management, or only a certain visitor).
+#   This is an array of strings in the format:
+#      - "field=value -> level" to match a value exactly, e.g. "tag=manager -> trace"
+#      - "field -> level" to match any value, e.g. "time_taken_ms -> debug"
+#   Warning: Using log-level-overrides has a performance penalty. Only use it for temporary debugging.
+#
+# Example (good for production):
+#   log-level: info
+#   log-format: json
+#   log-file: /var/log/ntfy.log
+#
+# Example level overrides (for debugging, only use temporarily):
+#   log-level-overrides:
+#      - "tag=manager -> trace"
+#      - "visitor_ip=1.2.3.4 -> debug"
+#      - "time_taken_ms -> debug"
+#
+# log-level: info
+# log-level-overrides:
+# log-format: text
