When your business needs to integrate ticketing into its existing infrastructure, API quality is determining. A poorly designed API means months of development, constant bugs, and limitations you discover too late. This guide helps you evaluate what to look for before committing to a platform.
Documentation: the first signal
Documentation quality reflects API maturity. Look for these elements:
- OpenAPI/Swagger specification: allows automatic client generation
- Code examples: in languages you use (JS, Python, PHP...)
- Use case guides: not just reference, also tutorials
- Changelog: change history and versioning policy
- Status page: visibility on service availability
Authentication and security
The API handles sensitive data and economic transactions. Security is non-negotiable.
- OAuth 2.0: modern authentication standard
- API keys with scopes: granular permissions per key
- Credential rotation: ability to rotate without downtime
- Rate limiting: protection against abuse, with documented limits
- Access logs: audit of who accesses what
Essential endpoints
Verify that the API covers all operations you need.
- Events: create, edit, list, manage states
- Tickets: types, prices, availability, reservations
- Orders: create, query, cancel, refund
- Validation: verify tickets, register accesses
- Webhooks: event notifications (sale, access, etc.)
Webhooks: real-time integration
Webhooks are critical for keeping your system synchronized without constant polling.
- Available events: what actions trigger webhooks
- Documented payload: clear structure of each event type
- Retries: what happens if your endpoint fails
- Signature verification: to validate the webhook is authentic
- Logs: history of webhooks sent and their status
Test environment
Developing against production is a recipe for disaster. Demand an adequate sandbox.
- Separate sandbox environment: test data without affecting production
- Test cards: to simulate payments without real charges
- Sample data: preloaded events and tickets for testing
- Production parity: same behavior, same responses
Technical support
When something fails at 2 AM before your event, you need quick answers.
- Technical channel: access to developers, not just generic support
- Documented SLA: committed response times
- Community: forum or Slack to resolve questions
- Technical onboarding: guided integration session
Conclusion
A good ticketing API accelerates your development, reduces bugs, and lets you build customized experiences. A bad API traps you in limitations you discover too late. Invest time in evaluating before committing: request sandbox access, test critical endpoints, and talk to the technical team. The right decision will save you months of frustration.
