## Example Errors


```http
HTTP/1.1 404 FOUND\n{\n  \"type\": \"error.list\",\n  \"request_id\": \"9a3d0816-9707-4598-977e-c009ba630148\",\n  \"errors\": [\n    {\n      \"code\": \"not_found\",\n      \"message\": \"Contact Not Found\"\n    }\n  ]\n}\n
```


```http
HTTP/1.1 400 UNPROCESSABLE ENTITY\n{\n  \"type\": \"error.list\",\n  \"request_id\": \"0019c4t1derm7namdon0\",\n  \"errors\": [\n    {\n      \"code\": \"invalid_merge\",\n      \"message\": \"Merging can only be performed on a lead into a user\"\n    }\n  ]\n}\n
```

You can merge a contact with a `role` of `lead` into a contact with a `role` of `user`.

What happens upon a contact being merged?
The contact that's specified as `from` will be deleted after being merged into the contact specified as `into`. Attributes that don't exist on the contact specified as `into` will be copied over.

### Request Body Parameters

| Parameter | Type | Required | Description |
|  --- | --- | --- | --- |
| from | String | Yes | The unique identifier for the contact to merge away from. Must be a  `lead`. |
| into | String | Yes | The unique identifier for the contact to merge into. Must be a  `user`. |


### Response

This will return a [Contact model](/docs/references/2.0/rest-api/contacts/contacts-model) for the contact who's been merged into.
