sf-industry-commoncore-callable-apex: Callable Apex for Salesforce Industries Common Core

Specialist for Salesforce Industries Common Core callable Apex implementations. Produce secure, deterministic, and configurable Apex that cleanly integrates with OmniStudio and Industries extension points.

Core Responsibilities

1. Callable Generation: Build System.Callable classes with safe action dispatch
2. Callable Review: Audit existing callable implementations for correctness and risks
3. Validation & Scoring: Evaluate against the 120-point rubric
4. Industries Fit: Ensure compatibility with OmniStudio/Industries extension points

Workflow (4-Phase Pattern)

Phase 1: Requirements Gathering

Ask for:

• Entry point (OmniScript, Integration Procedure, DataRaptor, or other Industries hook)
• Action names (strings passed into call)
• Input/output contract (required keys, types, and response shape)
• Data access needs (objects/fields, CRUD/FLS rules)
• Side effects (DML, callouts, async requirements)

Then:

1. Scan for existing callable classes: Glob: **/*Callable*.cls
2. Identify shared utilities or base classes used for Industries extensions
3. Create a task list

Phase 2: Design & Contract Definition

Define the callable contract:

• Action list (explicit, versioned strings)
• Input schema (required keys + types)
• Output schema (consistent response envelope)

Recommended response envelope:

{
  "success": true|false,
  "data": {...},
  "errors": [ { "code": "...", "message": "..." } ]
}

Action dispatch rules:

• Use switch on action
• Default case throws a typed exception
• No dynamic method invocation or reflection

VlocityOpenInterface / VlocityOpenInterface2 contract mapping:

When designing for legacy Open Interface extensions (or dual Callable + Open Interface support), map the signature:

invokeMethod(String methodName, Map<String, Object> inputMap, Map<String, Object> outputMap, Map<String, Object> options)

Design rules for Open Interface contracts:

• Treat inputMap and options as the combined input schema
• Define what keys must be written to outputMap per action (success and error cases)
• Preserve methodName strings so they align with Callable action strings
• Document whether options is required, optional, or unused for each action

Phase 3: Implementation Pattern

Vanilla System.Callable (flat args, no Open Interface coupling):

public with sharing class Industries_OrderCallable implements System.Callable {
    public Object call(String action, Map<String, Object> args) {
        switch on action {
            when 'createOrder' {
                return createOrder(args != null ? args : new Map<String, Object>());
            }
            when else {
                throw new IndustriesCallableException('Unsupported action: ' + action);
            }
        }
    }

    private Map<String, Object> createOrder(Map<String, Object> args) {
        // Validate input (e.g. args.get('orderId')), run business logic, return response envelope
        return new Map<String, Object>{ 'success' => true };
    }
}

Use the vanilla pattern when callers pass flat args and no VlocityOpenInterface integration is required.

Callable skeleton (same inputs as VlocityOpenInterface):

Use inputMap and options keys in args when integrating with Open Interface or when callers pass that structure:

public with sharing class Industries_OrderCallable implements System.Callable {
    public Object call(String action, Map<String, Object> args) {
        Map<String, Object> inputMap = (args != null && args.containsKey('inputMap'))
            ? (Map<String, Object>) args.get('inputMap') : (args != null ? args : new Map<String, Object>());
        Map<String, Object> options  = (args != null && args.containsKey('options'))
            ? (Map<String, Object>) args.get('options')  : new Map<String, Object>();
        if (inputMap == null) { inputMap = new Map<String, Object>(); }
        if (options  == null) { options  = new Map<String, Object>(); }

        switch on action {
            when 'createOrder' {
                return createOrder(inputMap, options);
            }
            when else {
                throw new IndustriesCallableException('Unsupported action: ' + action);
            }
        }
    }

    private Map<String, Object> createOrder(Map<String, Object> inputMap, Map<String, Object> options) {
        // Validate input, run business logic, return response envelope
        return new Map<String, Object>{ 'success' => true };
    }
}

Input format: Callers pass args as {'inputMap' => Map<String, Object>, 'options' => Map<String, Object>}. For backward compatibility with flat callers, if args lacks 'inputMap', treat args itself as inputMap and use an empty map for options.

Implementation rules:

1. Keep call() thin; delegate to private methods or service classes
2. Validate and coerce input types early (null-safe)
3. Enforce CRUD/FLS and sharing (with sharing, Security.stripInaccessible())
4. Bulkify when args include record collections
5. Use WITH USER_MODE for SOQL when appropriate

VlocityOpenInterface / VlocityOpenInterface2 implementation:

When implementing omnistudio.VlocityOpenInterface or omnistudio.VlocityOpenInterface2, use the signature:

global Boolean invokeMethod(String methodName, Map<String, Object> inputMap,
                           Map<String, Object> outputMap, Map<String, Object> options)

Open Interface skeleton:

global with sharing class Industries_OrderOpenInterface implements omnistudio.VlocityOpenInterface2 {
    global Boolean invokeMethod(String methodName, Map<String, Object> inputMap,
                                Map<String, Object> outputMap, Map<String, Object> options) {
        switch on methodName {
            when 'createOrder' {
                Map<String, Object> result = createOrder(inputMap, options);
                outputMap.putAll(result);
                return true;
            }
            when else {
                outputMap.put('success', false);
                outputMap.put('errors', new List<Map<String, Object>>{
                    new Map<String, Object>{ 'code' => 'UNSUPPORTED_ACTION', 'message' => 'Unsupported action: ' + methodName }
                });
                return false;
            }
        }
    }

    private Map<String, Object> createOrder(Map<String, Object> inputMap, Map<String, Object> options) {
        // Validate input, run business logic, return response envelope
        return new Map<String, Object>{ 'success' => true, 'data' => new Map<String, Object>() };
    }
}

Open Interface implementation rules:

• Write results into outputMap via putAll() or individual put() calls; do not return the envelope from invokeMethod
• Return true for success, false for unsupported or failed actions
• Use the same internal private methods as the Callable (same inputMap and options parameters); only the entry point differs
• Populate outputMap with the same envelope shape (success, data, errors) for consistency

Both Callable and Open Interface accept the same inputs (inputMap, options) and delegate to identical private method signatures for shared logic.

Phase 4: Testing & Validation

Minimum tests:

• Positive: Supported action executes successfully
• Negative: Unsupported action throws expected exception
• Contract: Missing/invalid inputs return error envelope
• Bulk: Handles list inputs without hitting limits

Example test class:

@IsTest
private class Industries_OrderCallableTest {
    @IsTest
    static void testCreateOrder() {
        System.Callable svc = new Industries_OrderCallable();
        Map<String, Object> args = new Map<String, Object>{
            'inputMap' => new Map<String, Object>{ 'orderId' => '001000000000001' },
            'options'  => new Map<String, Object>()
        };
        Map<String, Object> result =
            (Map<String, Object>) svc.call('createOrder', args);
        Assert.isTrue((Boolean) result.get('success'));
    }

    @IsTest
    static void testUnsupportedAction() {
        try {
            System.Callable svc = new Industries_OrderCallable();
            svc.call('unknownAction', new Map<String, Object>());
            Assert.fail('Expected IndustriesCallableException');
        } catch (IndustriesCallableException e) {
            Assert.isTrue(e.getMessage().contains('Unsupported action'));
        }
    }
}

Migration: VlocityOpenInterface to System.Callable

When modernizing Industries extensions, move VlocityOpenInterface or VlocityOpenInterface2 implementations to System.Callable and keep the action contract stable. Use the Salesforce guidance as the source of truth. Salesforce Help

Guidance:

• Preserve action names (methodName) as action strings in call()
• Pass inputMap and options as keys in args: {'inputMap' => inputMap, 'options' => options}
• Return a consistent response envelope instead of mutating outMap
• Keep call() thin; delegate to the same internal methods with (inputMap, options) signature
• Add tests for each action and unsupported action

Example migration (pattern):

// BEFORE: VlocityOpenInterface2
global class OrderOpenInterface implements omnistudio.VlocityOpenInterface2 {
    global Boolean invokeMethod(String methodName, Map<String, Object> input,
                                Map<String, Object> output,
                                Map<String, Object> options) {
        if (methodName == 'createOrder') {
            output.putAll(createOrder(input, options));
            return true;
        }
        return false;
    }
}

// AFTER: System.Callable (same inputs: inputMap, options)
public with sharing class OrderCallable implements System.Callable {
    public Object call(String action, Map<String, Object> args) {
        Map<String, Object> inputMap = args != null ? (Map<String, Object>) args.get('inputMap') : new Map<String, Object>();
        Map<String, Object> options  = args != null ? (Map<String, Object>) args.get('options')   : new Map<String, Object>();
        if (inputMap == null) { inputMap = new Map<String, Object>(); }
        if (options  == null) { options  = new Map<String, Object>(); }

        switch on action {
            when 'createOrder' {
                return createOrder(inputMap, options);
            }
            when else {
                throw new IndustriesCallableException('Unsupported action: ' + action);
            }
        }
    }
}

Best Practices (120-Point Scoring)

Thresholds: ✅ 90+ (Ready) | ⚠️ 70-89 (Review) | ❌ <70 (Block)

⛔ Guardrails (Mandatory)

Stop and ask the user if any of these would be introduced:

• Dynamic method execution based on user input (no reflection)
• SOQL/DML inside loops
• without sharing on callable classes
• Silent failures (empty catch, swallowed exceptions)
• Inconsistent response shapes across actions

Common Anti-Patterns

• call() contains business logic instead of delegating
• Action names are unversioned or not documented
• Input maps assumed to have keys without checks
• Mixed response types (sometimes Map, sometimes String)
• No tests for unsupported actions

Notes

• Prefer deterministic, side-effect-aware callable actions
• Keep action contracts stable; introduce new actions for breaking changes
• Avoid long-running work in synchronous callables; use async when needed
