How to Use Airtable API for App

[TrueDevz]

Hello Team I am new to Airtable. I am making a kids stories application.
At the base of mine are two tables.
1. Categories
2. Stories

For Stories List:
https://api.airtable.com/v0/appAqhAv602z9hmQk/stories?api_key=keymxFuQllagToOqD

For Stories Details:
https://api.airtable.com/v0/appAqhAv602z9hmQk/stories/{id}?api_key=keymxFuQllagToOqD

For Categories:
https://api.airtable.com/v0/appAqhAv602z9hmQk/categories?api_key=keymxFuQllagToOqD

List of stories and single story no problem...
But my problem is near category table.

After I select a category I want to get only stories related to that category. But whatever category is selected, all the stories are shown.
