Flawnter API security testing will scan your application REST APIs for security vulnerabilities. Currently it supports Postman collections in JSON format. If you have OpenAPI Specification (OAS) file, you can import in Postman as collection and then export it to JSON file. Our API security testing is similar to DAST except it tests only the APIs you define in the JSON file. Note when deepscan flag in flawnter.cfg is set to false the API security scan will perform faster scans, but if you want more deeper and accurate scans you can set deepscan flag to true. For the details please refer to our API Security Testing Guide here.
