Check that your APIs behave correctly, handle bad input and stay reliable.
Hibacu Labs tests APIs for correct behaviour, error handling, data validation and reliability, manually and with automation. Good API testing catches problems at the layer that mobile apps, websites and partners all depend on.
Who needs this

The problem
Is this for you?
Many clients depend on one API
A defect in an API breaks every app and partner using it.
Undocumented or inconsistent behaviour
Responses and errors differ from what the documentation says.
Changes that break consumers
Updates silently alter behaviour other systems rely on.
What Hibacu delivers
Capabilities
Functionality
Verify endpoints return the right data and status.
Authentication and authorization
Check who can call what, and that the rules hold.
Validation
Check how the API handles invalid and unexpected input.
Business logic
Verify the API enforces your actual business rules.
Error handling
Confirm errors are clear, consistent and safe.
Security-oriented API testing
Look for weaknesses an attacker could use.
Process
How we work
- 01
Review the API
We study the documentation and behaviour.
- 02
Design test cases
We cover normal use, errors and boundaries.
- 03
Execute
We test manually and automate what repeats.
- 04
Report
Findings are reported with requests and responses as evidence.
Deliverables
What you receive
- API test plan
- Test cases and, where agreed, an automated suite
- Findings report with evidence
- Retest confirmation
Security and quality
How we keep the work dependable
- Findings reported with the requests and responses as evidence
- Cases cover normal use, errors and boundaries
- Retest after fixes
Proof
Case studies
We publish only verified work that clients have approved. Until a case study for this service is ready, the best proof is a conversation, and our own products, which we build, test and secure ourselves.
FAQ
Frequently asked questions
What is API testing?
API testing checks the interfaces applications use to talk to each other, verifying data, behaviour and error handling without going through the user interface.
How is API testing different from API security testing?
API testing checks correctness and reliability. Security testing looks for weaknesses an attacker could exploit. We offer both.
