***I am getting a 409 error when provisioning a user, how do I resolve this?***

There may be cases where you were unable to save the user's Validic ID and Access Token during User Provisioning. When you try to provision the same user using the same 'uid', you get a 409 Conflict Response. Consider the following example:

**User Provisioning:**

```
POST ORGANIZATION_ID}/users.json
-H 'Content-Type: application/json'
{
    "user": {
        "uid": "12345"
    },
    "access_token": "{ORGANIZATION_ACCESS_TOKEN}"
}
409
{
    "code": 409,
    "message": "Conflict",
    "errors": "User already exists"
}
```

The error results from using the same 'uid' of "12345" which was already used to provision a user in your organization. To resolve this, you need to remove the user with that 'uid' or change the existing user's 'uid' in order to be able to provision the user again.

**Deleting a User Example**

```
DELETE ORGANIZATION_ID}/users.json
-H 'Content-Type: application/json'
{
    "uid": "12345",
    "access_token": "{ORGANIZATION_ACCESS_TOKEN}"
}
200
{
    "code": 200,
    "message": "Ok"
}​
```

**Changing a User's UID Example**

```
PUT ORGANIZATION_ID}/users/{USER_ID}.json
-H 'Content-Type: application/json'
{
    "user": {
        "uid": "54321"
    },
    "access_token": "{ORGANIZATION_ACCESS_TOKEN}"
}​
200
{
    "code": 200,
    "message": "The user has been successfully updated",
    "user": {
        "_id": "5544b41970ff411d8b000018",
        "uid": "54321",
        "profile": {
            "gender": null,
            "height": null,
            "location": null,
            "weight": null,
            "birth_year": null
        }
    }
}
```
