How to do automation API testing on native andriod app using appium

Can anyone help to understand how to do api testing on native android app .I’m automating my app using appium and have so many api’s so i need to automate but i dont know how to do API testing

Appium is for UI automation, for API automation there are other open source projected which are best suited e.g. rest-assured, karate etc
