Third-party applications do more than connect to digital platforms. They also inherit part of the platform’s trust.
A Shopee integration may pull orders, update product listings, manage shipments, or power customer communications. Along the way, it often handles personal data, access tokens, and business-critical functions as well. That access creates a security dependency that Shopee cannot fully control on its own.
A weakness in an external application can expose merchant data or buyer information. In some cases, it can also allow an attacker to take unauthorized actions on the platform itself. This is the primary reason Shopee and other major platforms increasingly require third-party developers to provide security evidence before granting that access.
The requirement is not simply about producing a report. It tests whether the integration protects the trust it has been given.
When Does Shopee Require a Penetration Test?
As of July 2026, Shopee Open Platform guidance outlines a specific requirement for penetration testing, commonly called pentesting.
It applies to Third-party Partner Platform developers who serve, or plan to serve, sellers in Thailand. The requirement applies specifically when those developers request access to buyer personally identifiable information.
Shopee has also published a mandatory report-submission policy for independent software vendors already accessing that data. The policy sets a compliance deadline of March 1, 2026, and requires reports to be renewed every two years.
There is also a broader contractual basis. Shopee’s Data Protection Policy gives Shopee the right to request a pentest report after providing reasonable notice, and it specifies that the test must be conducted by a third-party vendor Shopee has approved.
None of this amounts to a single universal requirement for every Shopee application. The applicable process depends on country, developer category, requested permissions, and the data being accessed, and Shopee may apply its own assessor or submission conditions as well. Developers should confirm those conditions before finalizing the assessment scope.
A technically sound report can still be rejected. This happens when the scope, environment, assessor, or report age does not meet what the platform requires.
Third-Party Applications Extend the Security Boundary
Digital platforms rely on APIs to support external services and integrations. These connections provide real operational value: they can automate inventory, synchronize products, consolidate orders, and support analytics. However, they also extend sensitive access into systems the platform itself does not operate.
A third-party application may hold API credentials, OAuth tokens, merchant information, and buyer data at the same time, often serving many merchants through a single shared environment. This makes the integration an attractive target in its own right. An attacker does not need to breach the main platform if the trusted integration next to it is easier to compromise.
The OWASP API Security Top 10 describes this kind of risk directly, identifying broken authorization, broken authentication, security misconfiguration, and unsafe API consumption as recurring problems. These issues become more serious in multi-tenant applications, where a single authorization failure can affect many customer accounts.
A platform can remain fully secure while the integration built on top of it exposes the access it was trusted with. That distinction should shape the scope of the pentest.
Why Manual Testing Matters
Automated scanners remain useful. They are effective at identifying known vulnerabilities, outdated components, exposed services, and common configuration errors.
However, scanners rarely understand business intent.
Consider a platform that assigns each order a unique identifier. A scanner can confirm that the endpoint functions correctly, but it will not test whether one merchant can request another merchant’s order simply by changing that identifier. The authentication control may work correctly while the authorization boundary still fails.
OWASP classifies this weakness as broken object-level authorization. It is exploited by changing identifiers within otherwise legitimate API requests. The same problem can affect administrative functions, account roles, token scopes, and merchant separation.
These issues require contextual testing, meaning the tester must understand what each user, tenant, and integration should be able to access. The OWASP Web Security Testing Guide provides a structured foundation for this work, covering authentication, authorization, session management, input validation, and configuration testing.
A useful assessment must go beyond identifying vulnerabilities. It should test whether those weaknesses can violate the application’s security model.
What Should the Assessment Validate?
A platform-focused pentest should follow the actual data flow and trust model.
The assessment should cover the web application, APIs, and administrative interfaces. Mobile applications may also require testing.
Authentication testing should examine login controls, session handling, account recovery, and privileged access. Authorization testing should use several roles and merchant accounts, since this is the only way to validate object, function, and tenant boundaries. API testing should cover documented and undocumented endpoints, as well as older versions, administrative functions, and sensitive business workflows.
OAuth testing should examine redirect handling, token storage, scope enforcement, revocation, and refresh-token protection. This area deserves particular attention, because a stolen token can provide trusted access without exposing a password. Our articles on modern credential theft and token theft examine this risk in more detail.
The supporting cloud environment may also belong in scope. Public services, storage, identity controls, and deployment systems can expose the application indirectly. The test should also follow sensitive data through logs, backups, exports, and development environments. A secure user interface does not compensate for exposed infrastructure or weak data handling.
How Other Platform Requirements Differ
Shopee is part of a wider platform-assurance trend, but each provider uses a different model. Treating these programs as interchangeable can lead to avoidable compliance and scoping errors.
Amazon Selling Partner API
Amazon’s vulnerability-management guidance requires annual pentesting for relevant solution providers. It also requires code vulnerability scanning before each release, and Amazon sets defined remediation periods for critical and high-risk findings.
This model extends beyond a single assessment. It connects penetration testing with software releases, remediation, retesting, and evidence retention. Developers should treat the report as one component of an ongoing vulnerability management program rather than a one-time requirement.
Google APIs and OAuth
Google uses a different process for applications requesting restricted OAuth scopes. Google’s security-assessment guidance requires an annual assessment for applications accessing those scopes. Successful applications receive a Letter of Validation from the security assessor.
Google’s annual recertification guidance requires reassessment every 12 months, covering the complete application even without major changes. This process should not be described as a generic annual pentest. It follows Google’s defined Cloud Application Security Assessment framework and OAuth verification process.
Microsoft 365
Microsoft 365 Certification uses a yearly independent audit that includes penetration testing along with reviews of data handling, privacy, and security practices. Microsoft’s submission guidance requires a manual pentest report completed within the previous 12 months. The report cannot consist only of automated scan results, and it must include the environment supporting the application.
Architecture therefore affects the scope. The assessment may need to cover hosting, infrastructure, and supporting services.
Salesforce AgentExchange
Salesforce now uses the AgentExchange name for its marketplace, though many developers still recognize the former AppExchange name. Solutions distributed through the marketplace must pass the Salesforce security-review process. Salesforce’s Product Security team tests submitted solutions, and the process also requires developers to complete their own preparation and testing.
Salesforce may also conduct periodic security re-reviews, which include automated and manual testing. This process does not universally require an independent pentest report. An independent assessment can still improve submission readiness, but it does not replace Salesforce’s own review.
Why Reports Fail to Provide Useful Assurance
A pentest report can appear professional while still providing limited value.
The most common problem is incomplete scope. Teams may test only the public website while excluding APIs, administrative interfaces, or cloud infrastructure. They may also test with a single user account, which cannot validate tenant separation or role boundaries.
Environment selection is another common problem. A simplified test environment may not reflect production architecture or data flows. Report age can also create rejection risk, since platforms often define validity periods or renewal schedules. The assessor requirement matters equally: Shopee, for example, can require a third-party vendor it has approved. Developers must confirm that requirement before signing an engagement.
The report should clearly identify the tested systems, dates, methods, limitations, and findings. It should also document remediation and retesting. Without those elements, the report may satisfy neither the platform nor the development team.
How Developers Should Prepare
Preparation should begin with the platform requirement rather than a generic testing package.
First, confirm the developer category, country, permissions, and information requested. Then map every application, API, mobile component, and supporting service involved. Provide test accounts with different roles and merchant relationships, since these accounts allow testers to challenge authorization boundaries. Document the architecture and sensitive data flows, including OAuth scopes, token handling, storage, logging, and third-party services. Finally, confirm the report format, assessor conditions, validity period, and retesting expectations.
Our guide on preparing for penetration testing explains the broader scoping process. Strong preparation improves coverage and reduces delays, scope changes, and unnecessary retesting.
Compliance Is the Trigger, Not the Objective
A platform requirement often initiates the assessment, but it should not define its full value.
The real objective is to test whether trusted platform access can be misused. A strong assessment can reveal cross-tenant exposure, weak token controls, or dangerous administrative paths, as well as weaknesses within cloud services and deployment systems. This evidence supports more than a single platform submission. It can also strengthen enterprise sales, procurement reviews, and customer assurance.
However, testing only provides a point-in-time view. The NIST Secure Software Development Framework recommends integrating security practices throughout the software development lifecycle. Developers should connect pentest findings with root-cause analysis, secure development, and recurring validation. This approach turns a compliance request into a stronger product-security program.

Frequently Asked Questions (FAQs)
Does every Shopee application require a penetration test?
No universal requirement applies to every application and country. Current Shopee guidance identifies specific conditions involving Thailand sellers and buyer personally identifiable information. Developers should confirm their requirements through Shopee Open Platform before arranging the assessment.
How often must the Shopee report be renewed?
Shopee’s mandatory submission policy states that relevant reports require renewal every two years. Developers should confirm whether additional conditions apply to their application or market.
Is a vulnerability scan enough?
Not when the platform requires manual penetration testing or a defined security assessment. Scanners cannot reliably test business logic, tenant separation, or complex authorization behavior.
Can one report support several platforms?
Possibly, but acceptance should never be assumed. Each platform can define different scope, assessor, report-age, remediation, and submission requirements.
