   This is my code : 

auth.js :

import axios from 'axios';

import * as actionTypes from './actionTypes';

export const authStart = () => {

    return {

        type: actionTypes.AUTH_START

    };

};

export const authSuccess = (authData) => {

     return {

        type: actionTypes.AUTH_SUCCESS,

        authData: authData

     };

};

export const authFail = (error) => {

   return {

      type: actionTypes.AUTH_FAIL,

      error: error

   };

};

export const auth = (email, password) => {

    return dispatch => {

        dispatch(authStart());

    const authData = {

       email: email,

       password: password,

       returnSecureToken: true

    };

  axios.post('https://identitytoolkit.googleapis.com/v1/accounts:signInWithCustomToken?key=[API_KEY]', authData)

       .then(response => {

        console.log(response);

         dispatch(authSuccess(response.data));

      })

       .catch(err => {

          console.log(err);

          dispatch(authFail(err));

       });

    };

   };

It seems you are sending your request to the wrong Endpoint. You should use this endpoint for user sign-up:

https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=[API_KEY]

And This one for sign-in:

https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=[API_KEY]

By the way, don't forget to replace "[API_KEY]" with your project's API key.

P.S.: You can also take a closer look at this official doc:
