linkedin com/in/dragos bulugean/ learn how to secure api documentation, prevent data leaks, and ensure compliance with best practices like rbac, encryption, and automated security checks secure your api documentation before it’s too late imagine this scenario you just publish a new update on the api documentation, but you forgot to blur sensitive end user information scary situation, right? in this article, we’ll show you how to avoid this problem ( and many others ) when writing and https //www archbee com/blog/importance of api documentation you’ll find out what security pitfalls to avoid and how to ensure data privacy in api documentation without having to limit accessibility \#data privacy in api documentation is mandatory \#exposing sensitive data in documentation can cost a lot when https //www archbee com/blog/how to write api documentation , you need to show various examples for your users to better understand the steps they need to take however, exposing sensitive data is a major risk if you share api keys or authentication tokens it can lead to unauthorized users gaining access to api they could exploit the api endpoints to retrieve or modify data or simply leak it online unfortunately, data breaches are not uncommon an australian telecommunications company, optus, experienced a https //www reuters com/technology/cybersecurity/australia takes singtel owned optus court over 2022 cyber attack 2024 05 22/ that exposed personal information of approximately 9 8 million current and former customers the breach was attributed to a coding error in an api's access control mechanism, which left the api vulnerable to unauthorized access this error remained undetected for 4 years before it was exploited in 2022, allowing attackers to access sensitive customer data such as names, dates of birth, home addresses, phone numbers, and identification document numbers in january 2024, a hacker leaked data from over https //equixly com/blog/2024/09/06/top 10 api breaches in 2024/ the issue came from a public rest api that didn’t need authentication, letting anyone access user info with just a username or id while emails were supposed to be private, a hidden flaw in the api let hackers check if an email was linked to a trello account based on the error message this mistake in the api documentation created a security risk, making it easier for attackers to find and target trello users that’s why you should treat your api as a member only club don’t allow all employees, third party contractors, or external vendors to gain access to sensitive data because they are at risk for social engineering attacks \#integrate regulatory frameworks in api documentation regulations like gdpr, and ccpa enforce strict data privacy and security standards, significantly impacting api documentation practices organizations must ensure that api documentation aligns with these regulations to protect user data and avoid legal penalties not to mention that not following these regulations can cost a lot! the https //www edpb europa eu/news/news/2023/12 billion euro fine facebook result edpb binding decision en? to date is 1 2 billion euros \#falling for these security pitfalls in api documentation? api documentation is essential for developers but can introduce security risks if not managed properly below are some critical security pitfalls that you should be aware of and actively mitigate \#hardcoding secrets in example requests sometimes, mistakes happen including real https //www fortinet com/resources/cyberglossary/api key , oauth tokens, or authentication credentials in examples can happen however, hardcoded secrets can be accidentally exposed in public repositories, internal documents, or api calls this can lead to unauthorized access to apis also, automated scanning tools can detect and exploit exposed secrets plus, you can risk exposing sensitive end user data this is a security risk here’s what you should include instead \#access controls issues for internal or external documentation you might unintentionally expose sensitive api documentation to the public or fail to enforce proper access controls for internal teams misconfigurations can lead to internal documentation being https //developers google com/search/docs/crawling indexing , exposing critical implementation details publicly exposed documentation can reveal internal api structures, leading to security loopholes also, this can lead to data leakages and other security issues a notable example is the one from https //securityonline info/postman security lapse 30000 workspaces leak api keys more/#google vignette , an api development and testing platform in december 2024, it was discovered that over 30,000 publicly accessible postman workspaces were exposing sensitive information , including api keys, tokens, and confidential business data the exposure was primarily caused by misconfigured access controls and poor data handling practices this highlights the risks associated with improperly managed api documentation and workspaces \#public facing docs need anonymity public api documentation should never include real user data a simple screenshot used for example can expose sensitive end user data like an email address, phone number, or even personal address apart from the potential gdpr or https //www cookiehub com/blog/what are the penalties for violating ccpa , you also risk privacy breaches that can lead to identity theft or fraud this can damage the user's trust and has a negative impact on your company’s reputation this is a security risk here’s what you should include in the api documentation instead \#best practices for secure api documentation \#require authentication and implement role based access controls authentication confirms identities, while authorization assigns them their privileges it’s not just about keeping unauthorized users out; it’s about ensuring the right people have the right access apis are like city roads; without traffic management, chaos ensues implement single sign on (sso), multi factor authentication (mfa), or oauth based access controls to limit access also, using a private documentation platform like archbee can help you secure your api docs archbee’s permission settings allow teams to restrict, manage, and audit access to api documentation, ensuring that only https //www archbee com/blog/get more external api users can view and edit critical api details rbac goes beyond authentication by restricting api documentation access based on user roles this prevents lower lever users from accessing admin or internal api docs for instance, public users only have access to basic api docs, while developers can view internal api documentation, but not admin endpoints lastly, admins can view and modify all api documentation unauthorized users will receive a ”403 forbidden” error, even if they are authenticated h3 follow the principle of least privilege the principle of least privilege states that you should only grant the minimum level of access and permissions that are necessary for your users or applications to perform their tasks this reduces the risk of unauthorized or unintended actions , such as modifying, deleting, or leaking your data or systems you should follow this principle when designing and https //www archbee com/blog/api documentation checklist , and only expose the endpoints, parameters, methods, and data that are relevant and essential for your api functionality you should also document the roles and responsibilities of your api users and the consequences and remedies for any violations or errors using environment variables instead of exposing api keys https //medium com/chingu/an introduction to environment variables and how to use them f602f66d15fa are secure, external configuration settings that store sensitive information , such as api keys, database credentials, and authentication tokens, outside the source code this prevents developers from hardcoding secrets directly in https //www archbee com/blog/api documentation tools or source code, reducing the risk of accidental exposure in public repositories, logs, or documentation using environment variables helps you prevent accidental leaks, enhances security, and allows you to separate configuration from https //www archbee com/blog/code documentation best practices plus, you are in compliance with security standards such as gdpr and iso 27001 audit and redact sensitive data mistakes happen to avoid a simple mistake turning into a huge data breach, you should regularly check to see if any sensitive data has been exposed there are tools like https //trufflesecurity com/trufflehog , https //www gitguardian com/ , or https //gitleaks io/ to scan repositories for exposed api keys implement ci/cd security checks before deploying api documentation if you find any issues, replace real credentials with placeholders and mask out any sensitive data access logs are recommended to track who is viewing or modifying the documentation h3 applying encryption and secure storage for internal documentation internal api documentation often contains sensitive system architecture details, admin apis, and confidential data encrypting and securely storing api documentation prevents unauthorized access using a private documentation platform like archbee provides built in access controls, authentication, and security measures necessary to keep your docs secure h3 keep api documentation up to date with security fixes api documentation is not a one time effort— it needs https //www archbee com/customers/traject data to reflect security patches, new authentication methods, and policy changes outdated documentation can lead to security vulnerabilities, api misuse, and compliance risks you should regularly check and remove references to outdated authentication methods (e g , deprecated api keys, old oauth flows) also, if a vulnerability is patched, explain what changed so developers can update their implementations \#how to balance transparency with security for api docs you don’t need to sacrifice transparency and accessibility for security archbee supports secure documentation, both for public and private documents \#centralized api documentation with version control with archbee, you don’t need to perform document https //www archbee com/blog/document version control manually a traditional file and folder system is time consuming and can lead to errors if end users access a deprecated version of your api documentation it’s a security risk you don’t want to take archbee centralizes api documentation in one secure location, making updates easier it helps maintain multiple api versions, ensuring deprecated security methods are clearly labeled also, teams can update security policies, authentication methods, and api changes instantly \#collaborate with other teams without exposing sensitive information when working on api documentation, different teams need access to documentation at various levels however, exposing sensitive information like internal api endpoints, authentication mechanisms, or infrastructure details to unauthorized users can lead to security risks and compliance issues with archbee, you can collaborate securely by controlling access , restricting content visibility, and ensuring role based permissions \#provide the right permission and access control every member of your team and all of your suppliers require the right permissions to view and modify api documentation https //docs archbee com/team access control is a key feature when it comes to high level docs you can assign specific roles to ensure the right access level also, you can limit access to internal api documentation for developers & security teams only \#don’t let a simple mistake turn into a full blown data breach api documentation is more than just a developer resource it’s a potential security risk if not managed properly a single exposed api key , misconfigured access control, or outdated security practice can open the door to unauthorized access, data leaks, and compliance violations by implementing strong security practices such as rbac, secret scanning, regular audits, and encryption, you can protect sensitive information while maintaining clear, developer friendly documentation start your https //app archbee com/signup? gl=1 1jv7n47 gcl au mtk1mteymjg2mc4xnzqwnjq1mzkx or https //www archbee com/book a demo for a personalized walkthrough to see how effortlessly you can keep your api documentation secure, up to date, and fully collaborative with archbee frequently asked questions why is it such a big deal if sensitive info shows up in my api docs? because secrets in docs act like keys if api keys, tokens, or real user data appear—even briefly—anyone who sees them can impersonate users, call your api, exfiltrate data, or alter resources documentation is often widely shared, cached, and indexed, so a short lived exposure can persist via search engines, screenshots, or forks automated scanners constantly hunt for leaked credentials, accelerating exploitation beyond technical damage, you face compliance and legal risk (gdpr/ccpa), incident response costs, and reputational harm high‑profile cases like optus (faulty api access control exposing 9 8m records) and trello (api behavior revealing private emails) show how documentation and api design missteps can lead to large scale compromises—even when the underlying app seems harmless how do i stop secrets from slipping into my api docs? what best practices keep api docs secure without making them hard to use? documentation, technical writing tips and trends blog join
