Rapid API working in postman but not in react-native app

I am using rapid api and it is working fine in postman but not working in react-native app.

 fetch("https://community-manga-eden.p.rapidapi.com/list/0", {"method": "GET","headers": {        Accept: "application/json","Content-Type": "application/json","x-rapidapi-host": "community-manga-eden.p.rapidapi.com","x-rapidapi-key": "55e095e2damshd8dd8bedc0fbde4p169b25jsn6898d56b4038"    }   })   .then(res => res.json())   .then(response => {    console.log(response);      this.setState({        data: response      })   })   .catch(err => {    console.log(err);   });
