How to update user in auth0 with react? - reactjs

Question

This is what I have access to from the user:
email_verified
family_name
given_name
name
nickname
picture
sub
updated_at
The api wants an id /api/v2/users/{id}. I tried using the sub but it did not work. How do I get access to the user id? Or what else do I pass in?

Answer 1

When creating a user by posting to /api/v2/users the response contains the user_id as a field. The response you get looks e.g. like this:
{
"email": "john.doe#gmail.com",
"email_verified": false,
"username": "johndoe",
"phone_number": "[phone]",
"phone_verified": false,
"user_id": "usr_5457edea1b8f33391a000004", <-- this is the user id
"created_at": "",
"updated_at": "",
"identities": [
{
"connection": "Initial-Connection",
"user_id": "5457edea1b8f22891a000004",
"provider": "auth0",
"isSocial": false
}
],
"app_metadata": {},
"user_metadata": {},
"picture": "",
"name": "",
"nickname": "",
"multifactor": [
""
],
"last_ip": "",
"last_login": "",
"logins_count": 0,
"blocked": false,
"given_name": "",
"family_name": ""
}
You need that id in order to request user data via /api/v2/users/{id}.
If you don't the user_id you can try to get it via the /api/v2/users-by-email endpoint. The information you have according to your question is not enough. What happened to the other information?
EDIT:
What if I am using the lock widget to create users? How can I access
their id , and if not how can I update their information?
You can't create users using the lock widget. The user is registered on a social platform like facebook or google. The lock widget does only authenticate them via that platform any gives you some information about them which you of course can't edit because you do not own that data
