Sf Connected Apps

sf-connected-apps: Salesforce Connected Apps & External Client Apps

Expert in creating and managing Salesforce Connected Apps and External Client Apps (ECAs) with OAuth configuration, security best practices, and metadata compliance.

Core Responsibilities

1. Connected App Generation: Create Connected Apps with OAuth 2.0 configuration, scopes, and callbacks
2. External Client App Generation: Create ECAs with modern security model and separation of concerns
3. Security Review: Analyze OAuth configurations for security best practices
4. Validation & Scoring: Score apps against 6 categories (0-120 points)
5. Migration Guidance: Help migrate from Connected Apps to External Client Apps

Workflow (5-Phase Pattern)

Phase 1: Requirements Gathering

Use AskUserQuestion to gather:

Then:

1. Check existing: Glob: **/*.connectedApp-meta.xml, Glob: **/*.eca-meta.xml
2. Create TodoWrite tasks

Phase 2: App Type Selection

Quick Decision:

• Multi-org or ISV → External Client App
• Regulated industry → External Client App (audit requirements)
• Simple single-org → Connected App sufficient
• Automated DevOps → External Client App (key rotation)

Phase 3: Template Selection & Generation

Template Locations (try in order):

1. ~/.claude/plugins/marketplaces/sf-skills/sf-connected-apps/templates/[template]
2. [project-root]/sf-connected-apps/templates/[template]

Template Selection:

Output Locations:

• Connected Apps: force-app/main/default/connectedApps/
• External Client Apps: force-app/main/default/externalClientApps/

Phase 4: Security Validation & Scoring

Scoring Categories:

Score: XX/120 ⭐⭐⭐⭐
├─ Security: XX/30 (PKCE, token rotation, IP restrictions, certificates)
├─ OAuth Config: XX/25 (callbacks, flows, token expiration, OIDC)
├─ Metadata: XX/20 (required fields, API version, naming)
├─ Best Practices: XX/20 (minimal scopes, named principal, pre-auth)
├─ Scopes: XX/15 (least privilege, no deprecated)
└─ Documentation: XX/10 (description, contact email)

Thresholds:

📋 Detailed scoring: See Phase 4 in previous version for point breakdown per criteria.

Phase 5: Deployment & Documentation

Deploy:

Skill(skill="sf-deploy", args="Deploy connected apps to [target-org] with --dry-run")

Completion Output:

✓ App Created: [AppName]
  Type: [Connected App | External Client App]
  Location: force-app/main/default/[connectedApps|externalClientApps]/
  OAuth Flow: [flow]
  Scopes: [list]
  Score: XX/120

Next Steps:
- Retrieve Consumer Key from Setup > App Manager
- Test OAuth flow (Postman/curl)
- For ECA: Configure policies in subscriber org

Metadata Structure Essentials

Connected App XML

<?xml version="1.0" encoding="UTF-8"?>
<ConnectedApp xmlns="http://soap.sforce.com/2006/04/metadata">
    <label>My Integration App</label>
    <contactEmail>admin@company.com</contactEmail>
    <description>Integration description</description>

    <!-- OAuth Configuration -->
    <oauthConfig>
        <callbackUrl>https://app.example.com/oauth/callback</callbackUrl>
        <certificate>MyCertificate</certificate> <!-- JWT Bearer only -->
        <scopes>Api</scopes>
        <scopes>RefreshToken</scopes>
        <isAdminApproved>true</isAdminApproved>
        <isConsumerSecretOptional>false</isConsumerSecretOptional>
        <isPkceRequired>true</isPkceRequired> <!-- Public clients -->
    </oauthConfig>

    <!-- OAuth Policy -->
    <oauthPolicy>
        <ipRelaxation>ENFORCE</ipRelaxation>
        <refreshTokenPolicy>infinite</refreshTokenPolicy>
        <isRefreshTokenRotationEnabled>true</isRefreshTokenRotationEnabled>
    </oauthPolicy>
</ConnectedApp>

External Client App Files

1. Header File ([AppName].eca-meta.xml):

<ExternalClientApplication xmlns="http://soap.sforce.com/2006/04/metadata">
    <label>My External Client App</label>
    <contactEmail>admin@company.com</contactEmail>
    <description>Modern integration</description>
    <distributionState>Local</distributionState> <!-- or Packageable -->
</ExternalClientApplication>

2. Global OAuth ([AppName].ecaGlblOauth-meta.xml):

<ExtlClntAppGlobalOauthSettings xmlns="http://soap.sforce.com/2006/04/metadata">
    <callbackUrl>https://app.example.com/oauth/callback</callbackUrl>
    <externalClientApplication>My_App_Name</externalClientApplication>
    <label>Global OAuth Settings</label>
    <isPkceRequired>true</isPkceRequired>
    <isConsumerSecretOptional>true</isConsumerSecretOptional>
</ExtlClntAppGlobalOauthSettings>

⚠️ Important: File suffix is .ecaGlblOauth (abbreviated), NOT .ecaGlobalOauth

3. Instance OAuth ([AppName].ecaOauth-meta.xml):

<ExtlClntAppOauthSettings xmlns="http://soap.sforce.com/2006/04/metadata">
    <externalClientApplication>My_App_Name</externalClientApplication>
    <commaSeparatedOauthScopes>api,refresh_token</commaSeparatedOauthScopes>
    <label>Instance OAuth Settings</label>
    <isClientCredentialsEnabled>false</isClientCredentialsEnabled>
</ExtlClntAppOauthSettings>

Scratch Org Setup (External Client Apps)

{
  "orgName": "ECA Development Org",
  "edition": "Developer",
  "features": [
    "ExternalClientApps",
    "ExtlClntAppSecretExposeCtl"
  ]
}

Common CLI Commands

# List Connected Apps in org
sf org list metadata --metadata-type ConnectedApp --target-org [alias]

# Retrieve Connected App
sf project retrieve start --metadata ConnectedApp:[AppName] --target-org [alias]

# Deploy
sf project deploy start --source-dir force-app/main/default/connectedApps --target-org [alias]

# Retrieve Consumer Key (after deployment)
# Go to Setup > App Manager > [App] > View

Migration: Connected App → External Client App

Quick Steps:

1. Assess: Glob: **/*.connectedApp-meta.xml
2. Create: Map OAuth settings to ECA structure
3. Parallel: Deploy ECA alongside old app
4. Test: Verify flows with new Consumer Key
5. Cutover: Update integrations, disable old app
6. Archive: Remove after 30-day grace period

Scoring Benefit: ECAs typically score 15-20 points higher.

📘 Detailed migration: See docs/migration-guide.md for step-by-step process.

Cross-Skill Integration

Key Insights

Notes

• API Version: 62.0+ recommended, 61.0+ required for External Client Apps
• Scoring: Block deployment if score < 54 (54% threshold)
• Consumer Secret: Never commit to version control - use environment variables
• External Client Apps: Preferred for new development (modern security model)
• Testing: Use Postman for OAuth flow testing before production
