Sorry for dumb questions but I kinda new for backend development. Recently I started to work in one company as front-end developer. But the problem is that company has existing serverless back-end project which is working on node.js, and there are lots of APIs which are not in Postman. And some of the APIs are updated they use new Request bodies but in Postman they still have old Body requests. So i need to use some of the APIs but don't know how request body should look like, and for some of the APIs i don't even know paths. Project uses AWS: Lambda, Api Gatawey, EC2,AWS Cognito, CloudFormation, Amplify, Route53, SSM.
Is there any ways how and where i can get request bodies and paths for all APIs ? I went through internet and spent already for 2 days, but still can't find anything on this subject. Would be very grateful for any tips.
