Key Insights

Insight	Details	Action
Named Credential Architecture	Legacy (pre-API 61) vs External Credentials (API 61+)	Check org API version first
Callouts in Triggers	Synchronous callouts NOT allowed in triggers	Always use async (Queueable, @future)
Governor Limits	100 callouts per transaction, 120s timeout max	Batch callouts, use async patterns
External Services	Auto-generates Apex from OpenAPI specs	Requires Named Credential for auth

---

⚠️ CRITICAL: Named Credential Architecture (API 61+)

Legacy Named Credentials vs External Credentials

Feature	Legacy Named Credential	External Credential (API 61+)
API Version	Pre-API 61	API 61+ (Winter '24+)
Principal Concept	Single principal per credential	Named Principal + Per-User Principal
OAuth Support	Basic OAuth 2.0	Full OAuth 2.0 + PKCE, JWT
Permissions	Profile-based	Permission Set + Named Principal
Recommendation	Legacy orgs only	Use for all new development

Workflow (5-Phase Pattern)

Phase 1: Requirements Gathering

Use AskUserQuestion to gather:

1. Integration Type: Outbound REST/SOAP, Inbound REST, Event-driven (Platform Events, CDC)
2. Authentication Method: OAuth 2.0 (Client Credentials, JWT Bearer, Authorization Code), Certificate-based, API Key/Basic Auth
3. External System Details: Base endpoint URL, API version, rate limits, required headers
4. Sync vs Async Requirements: Real-time response needed → Sync | Fire-and-forget or DML-triggered → Async (Queueable)

Phase 2: Template Selection

Integration Need	Template	Location
Named Credentials	oauth-client-credentials.namedCredential-meta.xml	templates/named-credentials/
External Credentials	oauth-external-credential.externalCredential-meta.xml	templates/external-credentials/
External Services	openapi-registration.externalServiceRegistration-meta.xml	templates/external-services/
REST Callouts	rest-sync-callout.cls, rest-queueable-callout.cls	templates/callouts/
SOAP Callouts	soap-callout-service.cls	templates/soap/
Platform Events	platform-event-definition.object-meta.xml	templates/platform-events/
CDC Subscribers	cdc-subscriber-trigger.trigger	templates/cdc/

Phase 3: Generation & Validation

File Locations:

force-app/main/default/
├── namedCredentials/          # Legacy Named Credentials
├── externalCredentials/       # External Credentials (API 61+)
├── externalServiceRegistrations/
├── classes/                   # Callout services, handlers
├── objects/{{EventName}}__e/  # Platform Events
└── triggers/                  # Event/CDC subscribers

Validate using scoring system (see Scoring System below)

Phase 4: Deployment

Deployment Order (CRITICAL):

1. Named Credentials / External Credentials FIRST
2. External Service Registrations (depends on Named Credentials)
3. Apex classes (callout services, handlers)
4. Platform Events / CDC configuration
5. Triggers (depends on events being deployed)

Use sf-deploy skill: Skill(skill="sf-deploy")

CLI Commands: See CLI Commands Reference

Phase 5: Testing & Verification

1. Test Named Credential: Setup → Named Credentials → Test Connection
2. Test External Service: Invoke generated Apex methods
3. Test Callout: Anonymous Apex or test class with Test.setMock()
4. Test Events: Publish and verify subscriber execution

---

Named Credentials

Auth Type	Use Case	Template	Key Config
OAuth 2.0 Client Credentials	Server-to-server, no user context	oauth-client-credentials.namedCredential-meta.xml	scope, tokenEndpoint
OAuth 2.0 JWT Bearer	CI/CD, backend services	oauth-jwt-bearer.namedCredential-meta.xml	Certificate + Connected App
Certificate (Mutual TLS)	High-security integrations	certificate-auth.namedCredential-meta.xml	Client cert required
Custom (API Key/Basic)	Simple APIs	custom-auth.namedCredential-meta.xml	username/password

Templates in templates/named-credentials/. ⚠️ NEVER hardcode credentials - always use Named Credentials!

---

External Credentials (API 61+)

Use Case: Modern OAuth 2.0 with per-user or named principal authentication

Template: templates/external-credentials/oauth-external-credential.externalCredential-meta.xml

Key Features:

• Named Principal vs Per-User Principal support
• OAuth 2.0 with PKCE
• JWT Bearer flow
• Permission Set-based access control

Quick Start:

<ExternalCredential xmlns="http://soap.sforce.com/2006/04/metadata">
    <label>{{CredentialLabel}}</label>
    <authenticationProtocol>Oauth</authenticationProtocol>
    <principals>
        <principalName>{{PrincipalName}}</principalName>
        <principalType>NamedPrincipal</principalType>
    </principals>
</ExternalCredential>

---

External Services (OpenAPI/Swagger)

Process:

1. Obtain OpenAPI 2.0 (Swagger) or 3.0 spec from external API
2. Create Named Credential for authentication
3. Register External Service in Salesforce (Setup → External Services OR via metadata)
4. Salesforce auto-generates Apex classes: ExternalService.{{ServiceName}}

Template: templates/external-services/openapi-registration.externalServiceRegistration-meta.xml

CLI Alternative:

sf api request rest /services/data/v62.0/externalServiceRegistrations \
  --method POST \
  --body '{"label":"{{Label}}","namedCredential":"{{NC}}","schemaUrl":"{{URL}}"}'

Usage Example:

ExternalService.Stripe stripe = new ExternalService.Stripe();
ExternalService.Stripe_createCustomer_Request req = new ExternalService.Stripe_createCustomer_Request();
req.email = '[e-mail]';
ExternalService.Stripe_createCustomer_Response resp = stripe.createCustomer(req);

Callout Patterns

REST Callouts

For detailed REST callout patterns, see resources/callout-patterns.md

Quick Reference

Pattern	Use Case	Template
Synchronous	User-initiated, need immediate response	rest-sync-callout.cls
Asynchronous (Queueable)	Triggered from DML (triggers), fire-and-forget	rest-queueable-callout.cls
Retry Handler	Handle transient failures with exponential backoff	callout-retry-handler.cls

Key Points:

• Use Named Credentials: req.setEndpoint('callout:{{NamedCredentialName}}/{{path}}')
• Set timeout: req.setTimeout(120000) (120s max)
• Handle status codes: 2xx success, 4xx client error (don't retry), 5xx server error (retry)

Detailed Examples:

• Synchronous REST Callout
• Asynchronous Queueable Callout
• Retry Handler with Exponential Backoff

SOAP Callouts

For detailed SOAP callout patterns, see resources/callout-patterns.md#soap-callout-patterns

Quick Reference

WSDL2Apex Process:

1. Setup → Apex Classes → Generate from WSDL
2. Upload WSDL file
3. Salesforce generates stub classes

Usage:

{{WsdlGeneratedClass}}.{{PortType}} stub = new {{WsdlGeneratedClass}}.{{PortType}}();
stub.endpoint_x = 'callout:{{NamedCredentialName}}';
stub.timeout_x = 120000;
return stub.{{OperationName}}(request);

Detailed Examples:

• WSDL2Apex Process
• SOAP Service Implementation

---

Event-Driven Patterns

Platform Events

For detailed Platform Event patterns, see resources/event-patterns.md#platform-events

Quick Reference

Event Types:

• Standard Volume: ~2,000 events/hour, 3-day retention
• High Volume: Millions/day, 24-hour retention, at-least-once delivery

Templates:

• Event Definition: templates/platform-events/platform-event-definition.object-meta.xml
• Publisher: templates/platform-events/event-publisher.cls
• Subscriber: templates/platform-events/event-subscriber-trigger.trigger

Publishing:

List<Database.SaveResult> results = EventBus.publish(events);

Subscribing:

trigger {{EventName}}Subscriber on {{EventName}}__e (after insert) {
    for ({{EventName}}__e event : Trigger.new) {
        {{EventName}}Handler.processEvent(event);
    }
}

Detailed Examples:

• Platform Event Definition
• Event Publisher
• Event Subscriber Trigger

Change Data Capture (CDC)

For detailed CDC patterns, see resources/event-patterns.md#change-data-capture-cdc

Quick Reference

Enablement: Setup → Integrations → Change Data Capture

Channel Naming: {{ObjectAPIName}}ChangeEvent (e.g., AccountChangeEvent)

Subscriber Template:

trigger {{ObjectName}}CDCSubscriber on {{ObjectName}}ChangeEvent (after insert) {
    for ({{ObjectName}}ChangeEvent event : Trigger.new) {
        EventBus.ChangeEventHeader header = event.ChangeEventHeader;
        String changeType = header.getChangeType(); // CREATE, UPDATE, DELETE, UNDELETE
        List<String> changedFields = header.getChangedFields();
        String recordId = header.getRecordIds()[0];

        switch on changeType {
            when 'CREATE' { {{ObjectName}}CDCHandler.handleCreate(event); }
            when 'UPDATE' { {{ObjectName}}CDCHandler.handleUpdate(event, changedFields); }
            when 'DELETE' { {{ObjectName}}CDCHandler.handleDelete(recordId); }
            when 'UNDELETE' { {{ObjectName}}CDCHandler.handleUndelete(event); }
        }
    }
}

Detailed Examples:

• CDC Enablement
• CDC Subscriber Trigger
• CDC Handler Service

🔧 Helper Scripts

sf-integration includes automation scripts to configure credentials without manual UI steps.

Available Scripts

Script	Purpose	Usage
configure-named-credential.sh	Set API keys via ConnectApi (Enhanced NC)	./scripts/configure-named-credential.sh <org-alias>
set-api-credential.sh	Store keys in Custom Settings (legacy)	./scripts/set-api-credential.sh <name> - <org-alias>

Auto-Run Behavior

When you create credential metadata files, Claude automatically suggests running the appropriate script:

File Pattern	Suggested Action
*.namedCredential-meta.xml	Run configure-named-credential.sh
*.externalCredential-meta.xml	Run configure-named-credential.sh
*.cspTrustedSite-meta.xml	Deploy endpoint security

Example Workflow

# 1. Claude generates credential metadata files
# 2. Hook detects and suggests next steps
# 3. Deploy metadata first
sf project deploy start --metadata ExternalCredential:WeatherAPI \
  --metadata NamedCredential:WeatherAPI \
  --target-org MyOrg

# 4. Run automation script
./scripts/configure-named-credential.sh MyOrg
# Enter API key when prompted (secure, hidden input)

Prerequisites

• Salesforce CLI v2+: sf command available
• Authenticated org: sf org login web -a <alias>
• Deployed metadata: External Credential and Named Credential deployed

📚 Documentation: See docs/named-credentials-automation.md for complete guide.

---

Anti-Patterns

Anti-Pattern	Problem	Correct Pattern
Hardcoded credentials	Security vulnerability, credential rotation nightmare	Use Named Credentials
Sync callout in trigger	CalloutException: Uncommitted work pending	Use Queueable with Database.AllowsCallouts
No timeout specified	Default 10s may be too short	Set req.setTimeout(120000) (max 120s)
No retry logic	Transient failures cause data loss	Implement exponential backoff
Ignoring status codes	Silent failures	Check statusCode and handle 4xx/5xx
100+ callouts per transaction	Governor limit exceeded	Batch callouts, use async
No logging	Can't debug production issues	Log all callout requests/responses
Exposing API errors to users	Security risk, poor UX	Catch and wrap in user-friendly messages
