I enabled this api but i got this error in my ionic app
**https://www.googleapis.com/identitytoolkit/v3/relyingparty/signupNewUser?key=AIzaSyAU1ymBJwG6sscjWS0Po4bP_yw4YQa-2SY 400 Bad Request**
please suggest me what is wrong there.
Based on your error message the problem is probably the following:
auth/operation-not-allowed
Thrown if the type of account corresponding to the credential is not enabled. Enable the account type in the Firebase Console, under the Auth tab.
For example if you use signInAnonymously()
you also have to enable anonymous authentication in your firebase console. So check your firebase console configuration.
