Using firebase RestApi to signup users using email and password - firebase

Question

I'm creating a project where users need to able to log in to their account and see some data. I'm creating a windows application with unity, so from what I understood from researching, I have to use the firebase RestAPI, not the SDK. I managed to use the realTime database but I'm struggling with the authentication side of things.
I followed this tutorial and used the documentation for signing up users into firebase with the RestAPI. I keep getting a 400 (Bad Request) error. I found this post, where the solution was to use a strong password, but that didn't work.
Since I'm using a not so reliable unity c# package as a client, I tested my code with nodeJs as well. Same error.
My code:
C#
private void SignUpUser(string email, string username, string password)
{
string userData = "{\"email\":\"" + email + "\",\"password\":\"" + password + "\",\"returnSecureToken\":true}";
// Content type is json by default
RestClient.Post<SignResponse>("https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=" + AuthKey, userData).Then(
response =>
{
Debug.Log("Success");
}).Catch(error =>
{
Debug.Log(error);
});
}
Javascript
const axios = require("axios");
axios
.post(
'https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=' + API_KEY,
{
email: "myEmddail#example",
password: "superStrongzi344##",
returnSecureToken: true,
},
{
'Content-Type': 'application/json',
}
)
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
Part of response:
response:
{ status: 400,
statusText: 'Bad Request',

config:

method: 'post',
data:

Is there anything I'm missing?
Thanks

Try enabling registering with e-mail in your firebase console. Also the c# library you're using doesn't seem very reliable and might not be well suited for error handling, I would suggest the native System.net.http library that's built in. An example of a request:
using System.Net.Http;
private static readonly HttpClient client = new HttpClient();
var values = new Dictionary<string, string>
{
{ "thing1", "hello" },
{ "thing2", "world" }
};
var content = new FormUrlEncodedContent(values);
var response = await client.PostAsync("http://www.example.com/recepticle.aspx", content);
var responseString = await response.Content.ReadAsStringAsync();
