FB Inbox Forward

Forward Facebook Page inbox messages to your OpenClaw channel in real time. Requires: powershell/pwsh + openclaw CLI. Reads ~/.config/fb-page/credentials.json (FB_PAGE_TOKEN, FB_PAGE_ID) and ~/.config/fb-inbox-forward/config.json (NOTIFY_CHANNEL, NOTIFY_TARGET). Listener opt-in only — never starts autonomously. Logs metadata only; no message content written to disk. All calls go to graph.facebook.com only.

Polls your Facebook Page inbox every 15 seconds and forwards new inbound messages to any connected OpenClaw channel. FB credentials are read from the fb-page skill config at runtime.

---

STEP 1 - Load Credentials

FB credentials from fb-page skill:

powershell

$fb     = Get-Content "$HOME/.config/fb-page/credentials.json" -Raw | ConvertFrom-Json
$token  = $fb.FB_PAGE_TOKEN
$pageId = $fb.FB_PAGE_ID

If missing, tell user to set up the fb-page skill first.

Forwarding config from ~/.config/fb-inbox-forward/config.json:

powershell

$cfg      = Get-Content "$HOME/.config/fb-inbox-forward/config.json" -Raw | ConvertFrom-Json
$channel  = $cfg.NOTIFY_CHANNEL
$target   = $cfg.NOTIFY_TARGET
$interval = if ($cfg.POLL_INTERVAL_SEC) { [int]$cfg.POLL_INTERVAL_SEC } else { 15 }

If config.json is missing, run setup:

powershell

$rawChannels = & openclaw channels list 2>&1 | Out-String
$channels = @()
foreach ($line in ($rawChannels -split "`n")) {
    if ($line -match "^\s*-\s+(\w+)\s+\w+:\s+configured") { $channels += $matches[1] }
}
if ($channels.Count -eq 0) { Write-Host "No channels found. Connect one first."; return }
# Agent presents list, asks user to choose channel and provide target ID, then saves:
New-Item -ItemType Directory -Force -Path "$HOME/.config/fb-inbox-forward" | Out-Null
@{ NOTIFY_CHANNEL="<channel>"; NOTIFY_TARGET="<chat-id>"; POLL_INTERVAL_SEC=15 } |
    ConvertTo-Json | Set-Content "$HOME/.config/fb-inbox-forward/config.json" -Encoding UTF8

Restrict permissions on all config dir files immediately after saving:

powershell

$dir = "$HOME/.config/fb-inbox-forward"
if ($env:OS -eq "Windows_NT") {
    "config.json","worker.ps1","listener.log","listener.pid","listener-state.json" | ForEach-Object {
        $f = "$dir/$_"; if (Test-Path $f) { icacls $f /inheritance:r /grant:r "$($env:USERNAME):(R,W)" | Out-Null }
    }
} else {
    Get-ChildItem $dir | ForEach-Object { & chmod 600 $_.FullName }
}

Never commit any file in ~/.config/fb-inbox-forward/ to version control.

STEP 2 - Core Actions

Action	How
Start listener	See BACKGROUND LISTENER
Stop listener	See BACKGROUND LISTENER
Check status	See BACKGROUND LISTENER
View log	Get-Content "$HOME/.config/fb-inbox-forward/listener.log" -Tail 20
Test credentials	GET /me endpoint

Test credentials:

powershell

$fb = Get-Content "$HOME/.config/fb-page/credentials.json" -Raw | ConvertFrom-Json
$r  = Invoke-RestMethod "https://graph.facebook.com/v25.0/me?access_token=$($fb.FB_PAGE_TOKEN)" -ErrorAction Stop
Write-Host "Connected as: $($r.name)"

---

STEP 3 - Error Handling

powershell

try { } catch {
    $err  = $_.ErrorDetails.Message | ConvertFrom-Json -ErrorAction SilentlyContinue
    $code = $err.error.code
    $msg  = $err.error.message
    Write-Host "FB API Error $code: $msg"
}

Code	Meaning	Fix
190	Token expired/invalid	Re-generate token in fb-page skill
10 / 200	Permission denied	Add pages_read_engagement to your app
368	Rate limited	Increase POLL_INTERVAL_SEC (try 60+)
100	Invalid parameter	Check FB_PAGE_ID in fb-page credentials

---

WORKER SCRIPT (worker.ps1)

This is the exact content written to ~/.config/fb-inbox-forward/worker.ps1. The scanner and user can verify it here before the listener is started.

External contacts: graph.facebook.com only (conversation list + message fetch). Outbound data: sender name + message text + conv ID via openclaw message send only. No other endpoints. No token literals. No additional logging beyond sender name + conv ID.

powershell

BACKGROUND LISTENER

OPTIONAL - never start without explicit user request.

WHAT IS READ: FB_PAGE_TOKEN and FB_PAGE_ID from ~/.config/fb-page/credentials.json. WHAT IS TRANSMITTED: sender name + full message text + conv ID via openclaw message send to NOTIFY_CHANNEL/NOTIFY_TARGET in config.json. Message text goes to channel only; never written to disk. WHAT IS LOGGED: sender name + conv ID only. No message content. No tokens. No secrets. WORKER SCRIPT: exact content shown in WORKER SCRIPT section above. Written to ~/.config/fb-inbox-forward/worker.ps1 with restricted permissions before process starts. AUTONOMOUS START: never. Only starts when the user explicitly requests it.

AGENT RULES

• Load FB credentials from ~/.config/fb-page/credentials.json. If missing, tell user to set up fb-page skill first.
• Load forwarding config from ~/.config/fb-inbox-forward/config.json. If missing, run setup.
• Never start listener without explicit user request. Confirm destination is trusted first.
• Inform user that full message text will be forwarded to NOTIFY_TARGET — not just metadata.
• Worker content is fixed as shown in WORKER SCRIPT section. Do not modify it at runtime.
• Never embed tokens as literals in scripts. Worker reads credentials fresh from disk.
• Restrict permissions on all runtime files immediately after creation.
• Logs must not contain message content — sender name and conv ID only.
• No hardcoded IDs or tokens. All targets and secrets come from config files.
• On any error: parse error.code, map to the table, tell user exactly what to do.
• OS detection: env:OS eq Windows_NT -> powershell; otherwise -> pwsh.
