AppExchange Integration Playbook for Warehousing: Security Review, Data Access, and Permission Design

Listing warehouse management solutions on Salesforce AppExchange requires passing a mandatory security review. The AppExchange security review confirms that applications protect customer data and follow Salesforce platform security standards. Understanding requirements early prevents costly redesigns and failed submissions.

What Does the AppExchange Security Review Evaluate?

The security review is a mandatory evaluation that every application must complete before appearing publicly on AppExchange. According to the Salesforce Developers Blog, the review validates that packages meet current best security practices and have no known vulnerabilities.

The review examines several critical security areas:

• SOQL Injections: Protection against malicious code injection attacks
• Cross-Site Scripting (XSS): Validation that apps do not allow unauthorized scripts
• CRUD/FLS Enforcement: Verification that users only access authorized data
• Authentication Protocols: Checks for secure authentication mechanisms
• Third-Party Libraries: Assessment of external dependencies for vulnerabilities

How to Implement CRUD and FLS in Warehouse Applications?

Create, Read, Update, Delete (CRUD) and Field-Level Security (FLS) are configured on profiles and permission sets to restrict access to objects and fields. Developers must design applications to enforce organizational CRUD and FLS settings on both standard and custom objects.

Salesforce provides multiple methods for enforcing security in Apex code. The Salesforce Trailhead security module recommends using user mode database operations as the preferred approach.

Key implementation methods include:

• stripInaccessible method: Removes fields from query results that the current user cannot access, preventing inadvertent data exposure
• User mode operations: Respects current user's profile and permission sets instead of running with elevated system privileges
• WITH SECURITY_ENFORCED clause: Validates field and object-level security permissions in SOQL queries

User mode database operations ensure that sharing rules, CRUD/FLS, and restriction rules are respected and enforced automatically.

What Data Access Controls Do Warehouse Applications Need?

Beyond CRUD/FLS, warehouse applications require granular data access controls to protect sensitive information.

Record-Level Security
Sharing rules determine which records users can view and edit. Warehouse applications should implement:

• Organization-Wide Defaults (OWD): Set private defaults for sensitive objects like customer data
• Sharing Rules: Grant access to specific user groups based on warehouse location or role
• Manual Sharing: Allow managers to share specific records with team members when needed

Data Visibility by Warehouse Location
Multi-warehouse operations require location-based data segregation. Workers at Warehouse A should not access inventory records from Warehouse B unless business rules permit.

Sensitive Field Protection
Certain fields require additional protection beyond object-level access:

• Customer payment information (restrict to billing roles only)
• Cost and margin data (restrict to finance and management)
• Employee performance metrics (restrict to supervisors)
• Integration credentials (restrict to system administrators)

How to Design Permissions for Warehouse Operations?

Warehouse applications involve multiple user types with different access needs. Designing permission sets for each role reduces security risks and maintains compliance.

Warehouse Workers

Workers need access to assigned tasks, inventory in work zones, and transaction recording capability. Permission sets should grant:

• Read access to inventory objects
• Write access for transaction recording
• Limited visibility to assigned orders only

Workers should not access financial data, customer personal information beyond shipping addresses, or inventory outside assigned zones.

Warehouse Managers

Managers require broader visibility across operations and work reassignment capabilities. Permission sets include:

• Read access to all warehouse inventory
• Visibility into worker productivity
• Ability to modify task assignments

Financial data access may be limited to operational costs without revenue or margin data.

System Administrators

Administrators need configuration access for warehouse locations, workflows, and integrations. Full CRUD access to warehouse configuration objects is required, along with permission set management for other users.

External Integration Users

API integrations from warehouse management systems require dedicated integration users with specific permissions. Integration users should have API-only access without UI login capability, restricted to objects required for integration functions.

Use OAuth for integration authentication rather than username/password credentials. OAuth tokens can be revoked without changing passwords.

What Are the Advantages of Proper Security Design?

Implementing comprehensive security controls before submission delivers measurable benefits.

• Faster security review approval (most apps pass within 2-3 submission cycles)
• Reduced resubmission costs ($999 per paid app submission attempt)
• Increased customer trust through AppExchange listing
• Compliance with enterprise security requirements
• Protection against data breach liability

Risks of Poor Security Preparation

Applications with inadequate security design face significant consequences. According to IBM's 2025 Cost of a Data Breach Report, U.S. organizations now face an average cost of $10.22 million per data breach incident.

• Failed security reviews causing launch delays
• Required code refactoring after vulnerabilities are identified
• Multiple resubmission fees accumulating costs
• Data exposure through inadequate FLS enforcement
• Potential removal from AppExchange for unresolved issues

Integration Security Best Practices

When warehouse applications integrate with external services, security vulnerabilities can emerge at connection points. Developers should review callback endpoints to ensure data does not leak beyond intended boundaries. Secure API endpoints must validate inputs, authenticate requests, and handle errors without exposing system details.

Secure API Design:

• Validate all incoming data before processing
• Use OAuth 2.0 for authentication instead of API keys or passwords
• Implement rate limiting to prevent abuse
• Return generic error messages without exposing stack traces

Data minimization principles apply to all integrations. Transfer only necessary data between Salesforce and warehouse systems. Avoid syncing entire customer records when only shipping addresses are needed for fulfillment operations.

Endpoint Security Requirements:

• Use HTTPS for all external communications
• Validate SSL certificates on outbound connections
• Implement IP allowlisting where possible
• Log all integration activity for audit trails

How Does Tejas Handle AppExchange Security?

Tejas Software's TWM AppExchange solution implements comprehensive security controls meeting Salesforce requirements. The Salesforce-native warehouse management system enforces CRUD and FLS through user mode database operations and stripInaccessible methods.

TWM AppExchange is preintegrated with Salesforce Order Management and supports inventory management, pick management, putaway management, PO receive, pick scan, and pack workflows. Permission sets are designed for specific warehouse roles, including workers, managers, administrators, and integration users. Each role receives minimum necessary access without excess privileges.

Prepare for Successful Security Review

AppExchange security review preparation requires thoughtful design of data access controls, permission structures, and integration security. Starting with security considerations during design reduces rework and accelerates approval.
