Environment reference¶

The canonical list lives in .env.example. This page groups variables by purpose.

Required¶

Variable	Purpose
`API_ID`	my.telegram.org API id
`API_HASH`	my.telegram.org API hash
`BOT_TOKEN`	@BotFather token
`MONGO_URI`	MongoDB connection string
`ADMIN_IDS`	Comma-separated Telegram user ids
`ADMIN_CHANNEL_ID`	Forum supergroup id (`-100…`)

Telegram session¶

Variable	Default	Notes
`SESSION_DIR`	`"."`	Directory pyrofork writes `*.session` to. On ephemeral hosts (Railway, Render, Fly, Heroku) point this at a persistent volume (e.g. `/data`) or every deploy re-runs `auth.ImportBotAuthorization` and Telegram rate-limits the bot with `FLOOD_WAIT_X`.

Logging¶

LOG_LEVEL, LOG_JSON, DEBUG_MODE, ERROR_LOG_TOPIC_ID.

SLA / auto-close / cooldown¶

SLA_WARN_MINUTES, SLA_BREACH_MINUTES, AUTO_CLOSE_DAYS, AUTO_CLOSE_SWEEP_MINUTES, COOLDOWN_RATE, COOLDOWN_WINDOW, COOLDOWN_MUTE_SECONDS.

i18n¶

DEFAULT_LANG (default en).

Redis (optional)¶

REDIS_URL, REDIS_NAMESPACE.

AI (optional)¶

AI_ENABLED, AI_MODEL_DEFAULT, AI_MODEL_FAST, AI_MODEL_VISION, AI_MODEL_TRANSCRIBE, AI_MAX_TOKENS, AI_TEMPERATURE, AI_REQUEST_TIMEOUT_S, AI_PII_REDACTION. Provider keys: ANTHROPIC_API_KEY, OPENAI_API_KEY, GEMINI_API_KEY.

Feature flags¶

FEATURE_AI_DRAFTS, FEATURE_AI_SUMMARY, FEATURE_AI_SENTIMENT, FEATURE_AI_ROUTING, FEATURE_AI_TRANSLATE, FEATURE_AI_TRANSCRIBE, FEATURE_AI_KB_DRAFTER, FEATURE_BUSINESS_HOURS, FEATURE_CSAT, FEATURE_ANALYTICS_DIGEST, FEATURE_KB_GATE, FEATURE_LINK_SCANNER, FEATURE_START_CAPTCHA, FEATURE_WEBHOOKS_OUT, FEATURE_DISCORD_BRIDGE, FEATURE_SLACK_BRIDGE, FEATURE_EMAIL_INGRESS, FEATURE_NEW_ONBOARDING, FEATURE_CUSTOMER_HISTORY_PIN, FEATURE_AGENT_INBOX.

Integrations¶

WEBHOOK_SECRET, CAPTCHA_SECRET, DISCORD_WEBHOOK_URL, SLACK_WEBHOOK_URL, DIGEST_TOPIC_ID.

REST API¶

Variable	Default	Notes
`API_ENABLED`	`false`	Set `true` to serve the FastAPI app alongside pyrofork
`API_HOST`	`0.0.0.0`	Bind address
`API_PORT`	`8000`	Local bind port; `$PORT` (Railway / Render / Fly / Heroku) takes precedence via `settings.effective_api_port`
`API_CORS_ORIGINS`	`""`	Comma-separated allow-list; `*` allows everything
`API_RATE_LIMIT_PER_MINUTE`	`120`	Per-key token bucket; needs Redis for multi-replica

Scopes recognised by /apikey create: tickets:read, tickets:write, projects:read, projects:write, users:read, analytics:read, webhooks:write, rules:read, rules:write, admin:full.

See also API quickstart, API authentication, and the dedicated Railway guide.

Admin SPA¶

Variable	Default	Notes
`WEB_ENABLED`	`true`	Mount the built React SPA at `/` with an `index.html` fallback so React-Router paths survive a refresh
`WEB_DIST_DIR`	`web/dist`	Path (from repo root) to the build output; override only if your CI puts it somewhere else

Dual-mode UI (Telegram WebApp)¶

See Web App feature and the dedicated Deploy the Web App guide for the full story.

Variable	Default	Notes
`UI_MODE`	`chat`	`chat` / `webapp` / `hybrid`. Typo-tolerant — unknown values fall back to `chat`
`WEBAPP_URL`	`""`	Public HTTPS URL of the Mini-App. Must match the WebApp domain configured via @BotFather
`WEBAPP_SET_MENU_BUTTON`	`false`	When true, the bot calls `setChatMenuButton` at boot so every chat shows a persistent "Open App" button
`WEBAPP_MENU_BUTTON_TEXT`	`Open App`	Label for the global menu button

Per-user overrides (users.ui_pref + graceful fallback for old clients or empty WEBAPP_URL) are described in the feature doc.

Observability¶

METRICS_ENABLED, METRICS_PATH, OTEL_SERVICE_NAME, OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_PROTOCOL, OTEL_TRACES_SAMPLER, OTEL_TRACES_SAMPLER_ARG.
