# Error "404. Wrong invite code"

An error occurs when attempting to join a group using an invite code.

```json
{    "error": {
        "code": 404,
        "message": "wrong invite code"
    }
}
```

**Main reasons:**

* The invitation code has been changed.
* The invitation code is invalid or contains extra characters (a common issue when copying and pasting manually)
* The group has reached its 1024 member limit
* Admin approval is required to join the group
* If you were previously removed from the group, WhatsApp blocks you from rejoining via the invitation link
* An invite was sent when attempting to add a member manually after an error occurred. This option cannot be used in the API; a link generated from the group settings is required.

Recommendation: Check that the code is up to date. Try joining the group via the WhatsApp mobile app or WhatsApp Web—the app usually displays a more specific reason why your request could not be completed.
