Issues

• [ ] #1015

  • The online Auctions API validator only checks if the item type in the body is a string.
  • When I tried calling the API, it failed.
  • The item type should be an available currency, such as "DINERO" or "NEELAM".
  • The quantity cannot exceed what you own.
  • This can cause issues for users unaware of these requirements.
  • It is important to update the validator to reflect these requirements and prevent future errors accurately.
  • Please fix this in the validator to improve user experience.

• [x] #1016

  • The Badges API works with form-data instead of raw JSON.
  • This is inconsistent with other APIs.
  • This inconsistency can cause confusion for developers.
  • Developers are used to working with raw JSON in other APIs.
  • It is important to have consistency in the API design.
  • Consistency improves the developer experience and reduces errors.

• [ ] #1017

  • There is no middleware validator present for the /challenges/subscribe API.
  • This can cause security issues.
  • It allows users to send any data to this endpoint.
  • Without a middleware validator, there is no way to ensure data validity and security.
  • This can lead to potential vulnerabilities and exploits.
  • It is important to implement a middleware validator to prevent these security issues.

• [ ] #1018

  • The name of the API used to make a user a member and archive them is not properly named with nouns.
  • These APIs do not return any response.
  • They should be fixed to return a proper response.
  • Having a properly named API with nouns can improve clarity and understanding for developers.
  • It is important for APIs to return a proper response.
  • This provides feedback and confirmation to the user.
  • It can improve the user experience and reduce confusion.

• [ ] #1019

  • The /stocks API response has two keys: message and stocks.
  • The message key returns a response such as success or failure.
  • The stocks key is an array of all the stocks.
  • The stocks key should be changed to data.
  • Changing the stocks key to data can improve clarity and consistency.
  • Rename the /stocks/users/self to /stocks/self
  • There is no API for buying and selling stocks.
  • You can only create stocks and get a list of all the stocks that have been created.
  • The lack of an API for buying and selling stocks can limit functionality and usefulness.
  • It is important to have APIs that support core features and actions.
  • Implementing APIs for buying and selling stocks can improve the user experience.
  • This provides more options for users.
