How should ticketing APIs and credentials be secured?
A ticketing API can expose customer records, live ticket inventory and operations that issue or invalidate admission rights. A compromised credential might allow an attacker to read personal information or perform actions with direct commercial and event-day consequences. Authentication proves who is calling; authorization decides what that caller may do. Both are required.
What is most sensitive about a ticketing API?
Endpoints that expose personal records, privileged configuration and ticket validity need particular care. Authorization must be checked against the requested customer, order, event and venue—not just against whether a token is valid. OWASP describes this as object-level and function-level authorization risk.
Which controls should be standard?
Prefer separate credentials by integration and environment. Keep privileged credentials out of client-side mobile/web applications unless the system has an explicitly designed user-delegated authentication flow.
Why is object-level authorization important?
An API may accept an order ID or ticket ID in a URL. It must verify that the caller may access that specific record, rather than merely accepting a valid token. OWASP identifies broken object-level authorization as a major API risk. Test requests against records from another venue, another brand and another customer’s account.
Token inheritance from a staff user’s permissions, described in Nuweb’s documentation, is one possible design. It does not remove the need to verify token scope, lifecycle and endpoint-specific authorization in production.
How should teams respond to a leaked token?
Maintain a way to revoke credentials promptly, inspect recent activity, reissue least-privilege tokens and assess whether records or tickets were affected. Document incident ownership, evidence preservation and required notifications based on applicable law.
Bottom line: secure APIs depend on scoped access, ongoing verification and a practical revocation plan—not a secret token alone.
Check authentication separately from authorisation
A valid API token establishes the caller’s identity or access context; it does not make every requested customer record or order accessible. For example, an integration with read-order permission for Brand A should fail when it requests a Brand B order, even if the token is valid. The OWASP API Security Top 10 distinguishes broken authentication, broken object-level authorisation and broken function-level authorisation. Test token rotation, expiry, least privilege, audit logging and rate limits. Also define how webhook recipients validate messages and what happens if a secret is compromised.
