About this Gig

Need to know whether your APIs, webhooks, and OAuth integrations are properly secured? Ill perform a focused security audit to identify authentication, authorization, validation, and permission weaknesses before they become serious vulnerabilities.


Ill review your API endpoints, authentication mechanisms, OAuth scopes, access tokens, webhook signatures, request validation, authorization logic, rate limiting, secrets, and integration permissions to identify security risks.


What I can help with:

  • API security assessment
  • Authentication & authorization review
  • OAuth permission & scope audit
  • Webhook signature validation
  • Request & payload validation
  • Token & credential security
  • API access-control testing
  • Excessive permission detection


Youll receive a prioritized API Security Action Plan highlighting the highest-risk findings and the recommended fixes.

Get a clearer picture of your integration security and reduce unnecessary access with a practical, developer-friendly security report.
