AEM Edge Delivery Services Authentication

Authenticate to obtain a token for all Edge Delivery Services admin operations. Auto-detects identity provider from org+site — no content source question needed. Opens the user's default browser for login and receives the token via a local callback server.

Token Usage

The authToken works for admin APIs:

API	Header	Usage
admin.hlx.page	x-auth-token: ${AUTH_TOKEN}	Preview, publish, status, code sync, jobs, logs, config
Config Service	x-auth-token: ${AUTH_TOKEN}	Sites, config, secrets, API keys, profiles

Note: admin.da.live uses a separate Adobe IMS token with Authorization: Bearer header. See the DA-specific login flow in ops/resources/da.md.

When to Use This Skill

• API returns 401 Unauthorized
• User says "login", "authenticate", "auth"
• Before any admin operation when token is missing/expired
• Before generating guides that need API access

Prerequisites

• Node.js installed

Authentication Flow

Step 1: Check Existing Token

Tokens are cached at the user level (~/.aem/ims-token.json), shared across all projects.

mkdir -p "${HOME}/.aem"

AUTH_TOKEN=$(node -e "
  const fs = require('fs');
  try {
    const t = JSON.parse(fs.readFileSync(process.env.HOME + '/.aem/ims-token.json', 'utf8'));
    if (t.authToken && t.authTokenExpiry > Math.floor(Date.now()/1000) + 60) {
      process.stdout.write(t.authToken);
    }
  } catch (e) {}
")

if [ -n "$AUTH_TOKEN" ]; then
  echo "Token valid"
  exit 0
fi

echo "Token missing or expired. Starting login..."

Step 2: Resolve Org and Site

The auto-login endpoint /login/{org}/{site}/main redirects to the correct identity provider automatically — no need to know the content source.

Resolve org and site from available sources (project-config, ops-config, git remote):

# Try project-config first (handover context)
ORG=$(cat .claude-plugin/project-config.json 2>/dev/null | node -e "
  const d = require('fs').readFileSync(0,'utf8');
  try { process.stdout.write(JSON.parse(d).org || ''); } catch(e) {}
")

# Fallback to ops-config (ops context)
if [ -z "$ORG" ]; then
  ORG=$(node -e "
    const fs = require('fs');
    try {
      const c = JSON.parse(fs.readFileSync(process.env.HOME + '/.aem/ops-config.json', 'utf8'));
      process.stdout.write(c.org || '');
    } catch(e) {}
  ")
fi

# Site: try git remote first, then ops-config
SITE=$(basename -s .git $(git remote get-url origin 2>/dev/null) 2>/dev/null)
if [ -z "$SITE" ]; then
  SITE=$(node -e "
    const fs = require('fs');
    try {
      const c = JSON.parse(fs.readFileSync(process.env.HOME + '/.aem/ops-config.json', 'utf8'));
      process.stdout.write(c.site || '');
    } catch(e) {}
  ")
fi

echo "org=${ORG:-NOT SET} site=${SITE:-NOT SET}"

If ORG is empty, ask the user:

"I need your organization name to authenticate. You can provide either:

• The org name (the {org} in https://main--site--{org}.aem.page)
• A preview/live URL like https://main--mysite--myorg.aem.page/"

If user provides a URL, parse org and site from it:

URL="$USER_INPUT"
if echo "$URL" | grep -q '\.aem\.page\|\.aem\.live'; then
  HOST_PART=$(echo "$URL" | cut -d'/' -f3 | cut -d'.' -f1)
  ORG=$(echo "$HOST_PART" | awk -F'--' '{print $NF}')
  SITE=$(echo "$HOST_PART" | awk -F'--' '{print $(NF-1)}')
  echo "Parsed from URL: org=$ORG site=$SITE"
fi

If SITE is still empty (not in a git repo and no URL provided), ask the user:

"I also need a site name to auto-detect your login provider. What is your site name? (the {site} part of https://main--{site}--{org}.aem.page)"

Do NOT proceed until both org and site are available.

Step 3: Capture Token via Loopback Redirect

Opens the user's default browser for login. A temporary local HTTP server receives the token callback after login completes. The user must click "Send" on the confirmation page to deliver the token. Works with all identity providers (Adobe IMS, Google, Microsoft).

User-facing message (display BEFORE running the script below):

Browser opened for login to {org}/{site}. Click "Send" after authenticating — you can close the tab once done.

Token Storage

User-level token cache — ~/.aem/ims-token.json:

{
  "authToken": "eyJ...",
  "authTokenExpiry": 1780489855
}

Field	Description
authToken	Admin JWT from login callback
authTokenExpiry	Unix timestamp when token expires (~24 hours)

Shared across every project on this machine. File is written with 0600 permissions.

---

Using the Token

# Read token from user-level cache
AUTH_TOKEN=$(node -e "
  const fs = require('fs');
  try {
    const t = JSON.parse(fs.readFileSync(process.env.HOME + '/.aem/ims-token.json', 'utf8'));
    process.stdout.write(t.authToken || '');
  } catch (e) {}
")

# admin.hlx.page and Config Service use the same header
curl -H "x-auth-token: ${AUTH_TOKEN}" "https://admin.hlx.page/status/{org}/{site}/main/"
curl -H "x-auth-token: ${AUTH_TOKEN}" "https://admin.hlx.page/config/{org}/sites.json"

---

Troubleshooting

Issue	Solution
Browser doesn't open	Manually open the URL printed in the terminal
"Send" button not working	Check browser console for errors; ensure no ad-blocker is blocking localhost requests
No authToken in callback	The helix-admin PR adding authToken to CLI login response has not yet been deployed
Token not received	Ensure you clicked "Send" on the confirmation page before the 5-minute timeout
401 after login	Token expired, re-authenticate
403 on API	User lacks permission for that org/site
State mismatch	Another process may have sent a rogue callback; re-run login

---

How It Works

1. CLI starts a temporary HTTP server on a random localhost port
2. Opens the user's default browser to admin.hlx.page/login/{org}/{site}/main with client_id=aem-cli and redirect_uri=http://localhost:{port}/...
3. Admin API auto-detects IDP (Google, Microsoft, Adobe) and redirects to login
4. User authenticates in their real browser
5. After login, admin API shows a confirmation page with a "Send" button
6. User clicks "Send" — browser POSTs { state, authToken } to localhost
7. CLI validates state nonce, saves authToken to ~/.aem/ims-token.json, exits
