# Optional local config file for telesrv.
# Copy to .env for local development. Do not commit real tokens or passwords.
# Complete reference:
#   docs/configuration.en.md
#   docs/configuration.zh-CN.md
#
# This file has two parts:
#   1. Everyday settings (below) -- IPs, ports, passwords, login methods,
#      SMTP, links, calls/streaming. These are the ones the server-panel.py
#      TUI shows and lets you edit, grouped the same way as here.
#   2. "Advanced / internal tuning" (further down) -- queue sizes, cache
#      limits, retention windows and similar performance knobs. Sensible
#      defaults are already set; most self-hosters never need to touch this
#      part, so it's left out of the panel to keep that screen readable.

## Server & Network -- Where the server listens and what address it tells clients to connect to.

# Address and port the server listens on for MTProto client connections.
TELESRV_LISTEN=0.0.0.0:2398
# Your server's public IP address.
TELESRV_ADVERTISE_IP=127.0.0.1
# Which "data center" number this server presents itself as. There's only
# ever one physical server, so this normally stays 2 -- no need to change it.
TELESRV_DC=2
# ISO 3166-1 alpha-2 code returned by help.getNearestDc. CN preselects +86.
TELESRV_DEFAULT_COUNTRY_CODE=US

## Phone Login Codes -- How a login code gets to a phone number when someone signs in.

# development: every phone number accepts the same fixed code below (fine
# for local testing, or when only email/Telegram sign-in is used). webhook:
# sends a real random code to TELESRV_OTP_WEBHOOK_URL for actual delivery.
TELESRV_PHONE_CODE_DELIVERY_PROVIDER=development
# The fixed code accepted for every phone number when the provider above is
# "development". Change this if you keep phone login open in that mode.
TELESRV_DEV_AUTH_CODE=12345
# How many digits a real (webhook-delivered) login code has.
TELESRV_PHONE_CODE_LENGTH=5
# How long a login code stays valid after being sent.
TELESRV_AUTH_CODE_TTL=5m
# How many wrong guesses are allowed before a code is rejected outright.
TELESRV_AUTH_CODE_MAX_ATTEMPTS=5
# Where webhook-delivered codes are POSTed, and the shared secret used to
# sign that request (see docs/otp-delivery.md for the exact payload).
TELESRV_OTP_WEBHOOK_URL=
TELESRV_OTP_WEBHOOK_SECRET=
TELESRV_OTP_WEBHOOK_TIMEOUT=5s

## Email Login & Signup -- Signing in (or registering) with an email address instead of a phone number.

# Lets an existing phone-number account also add an email address for login
# codes. REQUIRE_SETUP forces every account without one to set it up.
TELESRV_LOGIN_EMAIL_ENABLE=false
TELESRV_LOGIN_EMAIL_REQUIRE_SETUP=false
# How many digits an email login code has.
TELESRV_LOGIN_EMAIL_CODE_LENGTH=6
# How an email login code is actually delivered: smtp (send it yourself,
# see the SMTP section below) or webhook (reuses the phone webhook above).
TELESRV_EMAIL_CODE_DELIVERY_PROVIDER=smtp
# Lets people register and log in with just an email address, no phone
# number at all. Uses the same SMTP/webhook delivery as email login above.
TELESRV_EMAIL_SIGNUP_ENABLE=false
# Comma-separated phone-number prefixes randomly assigned as the visible
# "phone number" for email-signup accounts, e.g. "888,380,373". Purely
# cosmetic -- doesn't need a client update to change.
TELESRV_EMAIL_SIGNUP_PHONE_PREFIXES=888

## SMTP (Outgoing Email) -- The mail server used to send login/signup codes by email.

TELESRV_SMTP_HOST=
TELESRV_SMTP_PORT=587
TELESRV_SMTP_USERNAME=
TELESRV_SMTP_PASSWORD=
# Sender address and display name shown on outgoing emails.
TELESRV_SMTP_FROM=
TELESRV_SMTP_FROM_NAME=OwpenGram
# Encryption mode: starttls, tls, or none (use "none" for a local test
# server like Mailpit that doesn't support encryption at all).
TELESRV_SMTP_TLS=starttls
TELESRV_SMTP_TIMEOUT=10s

## Public Links & Branding -- What clients show/open for links, and your product's name.

# Public web address for links this server generates (invite links, sticker
# packs, etc). Use your real domain once you have one, e.g. https://example.com.
TELESRV_PUBLIC_BASE_URL=http://127.0.0.1
# Custom URL scheme (like "owpg://") that public pages use to open your
# patched client. Must match what your client builds were compiled with.
TELESRV_PUBLIC_APP_SCHEME=owpg
# Optional: use "scheme://yourdomain.com/..." links instead of plain
# "scheme://...". Leave empty unless you specifically need this.
TELESRV_PUBLIC_APP_LINK_BASE=
# Address of your web client (if you have one) and the product name shown
# on public landing pages.
TELESRV_PUBLIC_WEB_BASE_URL=https://web.telesrv.net
TELESRV_PUBLIC_APP_NAME=OwpenGram
# Where the "Download" button on public pages links to.

# Warning text shown on a profile/channel the admin panel flagged as
# scam/fake. Leave empty to use the built-in English text.
TELESRV_SCAM_WARNING=
TELESRV_FAKE_WARNING=

## Admin Panel -- Login and access for the web-based admin dashboard.

# Secret token shared between the main server and the admin panel process --
# both must use the exact same value, or the admin panel can't save changes.
TELESRV_ADMIN_API_TOKEN=
# Password to log into the admin panel (or use a token below instead; set
# at least one of the two).
TELESRV_ADMIN_UI_PASSWORD=
TELESRV_ADMIN_UI_TOKEN=
# Encrypts the admin panel's login session cookie. Use a random string of
# at least 32 characters; changing it logs everyone out.
TELESRV_ADMIN_SESSION_KEY=
# Address the main server exposes its admin API on. Leave empty to disable
# the admin panel entirely; set to a loopback address (127.0.0.1:...) to
# enable it without exposing it outside this machine.
TELESRV_ADMIN_API_ADDR=
# Address the admin panel's own web UI listens on.
TELESRV_ADMIN_UI_ADDR=127.0.0.1:2600
# Permissions granted to an Admin UI session that logged in with
# TELESRV_ADMIN_UI_PASSWORD / _TOKEN. Comma-separated; "*" means every
# permission and is the default, so enabling RBAC never locks an operator out of
# a panel that worked before. Names are letters/digits/._:- and may end in
# "namespace.*" to grant a whole namespace.
TELESRV_ADMIN_UI_PERMISSIONS=*
# Additional Admin API bearer tokens with a bounded permission set each, so an
# integration gets exactly the rights it needs instead of the unrestricted
# TELESRV_ADMIN_API_TOKEN. Format: "name:token:perm1,perm2" entries separated by
# ';'. A token may not contain ':' or whitespace, names and tokens must be
# unique, and reusing TELESRV_ADMIN_API_TOKEN here is refused; any malformed
# entry fails startup rather than silently granting or dropping rights.
TELESRV_ADMIN_SCOPED_TOKENS=

## Bot API Gateway -- Optional HTTP gateway for bot libraries (e.g. python-telegram-bot).

# Leave empty to disable. Set to an address like 127.0.0.1:2500 to enable.
TELESRV_BOT_API_ADDR=

## Database -- Where the server stores its data.

TELESRV_POSTGRES_DSN=postgres://owpengram:owpengram@127.0.0.1:5432/owpengram?sslmode=disable
TELESRV_REDIS_ADDR=127.0.0.1:6399
TELESRV_REDIS_PASSWORD=
TELESRV_REDIS_DB=0

## Public Web Listener -- Serves public profile pages, avatars, and sticker/emoji pack previews.

# Host:port this listens on (not a URL). Let nginx (or similar) proxy
# public traffic to it rather than exposing this port directly.
TELESRV_PUBLIC_LINK_WEB_ADDR=0.0.0.0:2401

## Telegram Login (OpenID Connect) -- Self-hosted "Log in with Telegram" for third-party sites.

# Keep disabled until you've generated the required key files with:
#   go run ./cmd/telegramloginkeygen -mode init
TELESRV_TELEGRAM_LOGIN_ENABLE=false
# The public HTTPS origin this login provider identifies itself as.
TELESRV_TELEGRAM_LOGIN_ISSUER=https://telesrv.net
# Allow plain HTTP instead of HTTPS (only for local testing).
TELESRV_TELEGRAM_LOGIN_ALLOW_HTTP=false

## Passkey Login (WebAuthn) -- Signing in with a device passkey/fingerprint instead of a code.

# Must match the real public domain you serve this from, or passkey login
# will fail (browsers check this against their own address bar).
TELESRV_PASSKEY_RP_ID=telesrv.net

## Calls -- Voice/video calls (1-to-1 and group), and the relay servers they need to work across networks.

# Turns off the TURN relay for 1-to-1 calls (falls back to direct
# connections only, which fail across most home/mobile networks).
TELESRV_TURN_ENABLE=true
# Port the built-in TURN/STUN relay listens on. Must be open in your firewall.
TELESRV_TURN_UDP_PORT=12400
# Public IP the relay tells clients to connect to. Leave empty to reuse
# TELESRV_ADVERTISE_IP above.
TELESRV_TURN_ADVERTISE_IP=
# Secret used to sign relay credentials. Leave empty for a random one
# generated at startup (fine for a single server instance).
TELESRV_TURN_SECRET=
# Port range the relay hands out for active call media. Must be open in
# your firewall.
TELESRV_TURN_RELAY_MIN_PORT=12500
TELESRV_TURN_RELAY_MAX_PORT=12999
# Turns off the group-call media server (SFU) -- group calls become
# signaling-only, with no actual audio/video.
TELESRV_SFU_ENABLE=true
# Single UDP port the group-call media server listens on. Must be open in
# your firewall.
TELESRV_SFU_UDP_PORT=12399
# Public IP the group-call media server tells clients to connect to. Leave
# empty to reuse TELESRV_ADVERTISE_IP above. Warning: setting this to
# 127.0.0.1 silently breaks calls from real devices.
TELESRV_SFU_ADVERTISE_IP=
# Maximum number of people allowed in one group call.
TELESRV_GROUPCALL_MAX_PARTICIPANTS=32

## Live Streaming -- Broadcasting live video into a channel (RTMP ingest, e.g. from OBS).

TELESRV_LIVESTREAM_ENABLE=true
# TCP address the RTMP ingest listens on for incoming streams.
TELESRV_LIVESTREAM_RTMP_ADDR=:2400
# Path to the ffmpeg executable used to process incoming streams. Leave as
# "ffmpeg" if it's already on your system PATH.
TELESRV_LIVESTREAM_FFMPEG_PATH=ffmpeg

## Maps -- Optional map previews (e.g. for shared locations) in patched clients.

# Mapbox access token. Leave empty to disable map previews.
TELESRV_MAPBOX_TOKEN=

## AI Features -- Optional AI-assisted message composing, business auto-replies, and translation.

# Master switch for the "improve my message" AI button in patched clients.
TELESRV_AI_ENABLED=true
# Auto-reply generator for Business accounts: "echo" just echoes the
# message back (safe default to verify the feature works end-to-end).
TELESRV_BUSINESS_AI_PROVIDER=echo
# Master switch for in-app message/chat translation.
TELESRV_TRANSLATION_ENABLED=true

## Moderation, Verification & Rating -- Toggles for the report-review queue, official/third-party verification, and the account-rating score.

# Reports and moderation-case review are always on; this only gates the
# official platform-checkmark flow applicants file through @verifybot. Rate
# limits and cooldowns for it live in the Advanced section below.
TELESRV_VERIFICATION_ENABLED=true
# Plain user accounts as verification subjects. Off by default: the official
# process verifies a public presence (bot, public channel, public supergroup).
TELESRV_VERIFICATION_ALLOW_USER_TARGETS=false
# Third-party bot verification marks (an icon + description shown before a
# peer's name) -- a separate mechanism from the checkmark above, not the
# platform badge. Its tuning lives in the Advanced section below.
TELESRV_BOT_VERIFICATION_ENABLED=true
# THIS FEATURE IS NOT FULLY FINISHED AND MAY CAUSE UNSTABLE SERVER BEHAVIOR.
# Hides third-party bot verification instead of removing it: the admin panel
# drops its "Third-party marks" nav entry and refuses every underlying route
# with 404 regardless of session permissions, and the built-in @marksbot
# service bot stops responding to messages entirely. Everything stays wired
# up (nothing is deleted), so setting this to false re-enables it. Default
# true -- leave it alone unless you are specifically testing this feature.
TELESRV_HIDE_THIRD_PARTY_VERIFICATION=true
# Local composite account-rating score (stars/activity/moderation-based).
# Shown to every viewer via userFull.stars_rating, not admin-only. Scoring
# weights and recompute timing live in the Advanced section below.
TELESRV_RATING_ENABLED=true

## Storage & Media -- Where uploaded media is stored, and how the server reacts to running low on space.

# Where uploaded media (photos, documents, stickers) is physically stored.
# "s3" (the default) writes to an S3-compatible object store -- out of the
# box that's the self-hosted MinIO container started by
# deploy/docker-compose.yml (see its "minio" service), pre-configured below
# to just work; point TELESRV_S3_* at AWS S3 instead if you'd rather not
# self-host it. "localfs" writes to TELESRV_BLOB_DIR on this machine's disk
# instead -- fully supported, just not the default. Switching backends only
# affects new uploads: existing files stay wherever they were written and
# remain readable/deletable as long as that backend's settings below stay
# filled in (don't blank out the old backend's config right after switching
# away from it, or its files become unreachable).
TELESRV_BLOB_BACKEND=s3
# Only used when TELESRV_BLOB_BACKEND=s3 (or after switching away from s3,
# for as long as old s3-stored files still need to stay reachable).
# Defaults below match deploy/docker-compose.yml's "minio" service exactly.

# MinIO needs this on (bucket in the URL path); AWS S3 does not.
TELESRV_S3_PATH_STYLE=true
# Reject new uploads once storage is nearly full, instead of letting the disk
# fill up. Thresholds live in the Advanced section below.
TELESRV_STORAGE_LOW_SPACE_GUARD_ENABLE=true
# Automatically delete old media once it's no longer referenced by any
# message, profile photo, or sticker set (never deletes media still visible
# in a conversation). Off by default -- storage usage is tracked and shown
# in the admin panel either way; enable this once you're comfortable with
# what it will reclaim. Retention age lives in the Advanced section below.
TELESRV_STORAGE_RETENTION_ENABLE=false
