`190` is Meta saying **the credential is no longer accepted**. The token expired, was revoked, had a permission
removed, or belongs to an app that changed. It is not about a message or a template: once it happens, nothing on
that number works.

## What Lynomia Chat does with it

Two authorization refusals in a row and the inbox is marked as needing reauthorization. That threshold exists so
one bad moment does not raise an alarm, and two does.

When it trips:

- a banner appears at the top of the dashboard saying you will not receive new messages until the connection is
  restored,
- the account's administrators are emailed,
- **incoming messages are still accepted and stored.** A broken outbound credential does not make Lynomia Chat
  throw away what customers send you — that was deliberate, and it is why you have the conversations to answer
  once you reconnect.

## What to do

Open **Settings → Inboxes → the inbox**.

| How the number was connected | Where to fix it |
|---|---|
| Through the guided WhatsApp sign-up | the inbox's **Configuration** tab — reconnect and approve the permissions again |
| With a token you pasted in yourself | **Configuration** — replace the token with a fresh one from your Meta app |

Then open **Account Health** and confirm the number reports normally. See
[reconnect a WhatsApp number](whatsapp-reconnect-a-number) for the whole sequence, including what to check if
reconnecting is refused.

## A worked example

An administrator removes a colleague from the Meta business portfolio on a Thursday. The token that colleague had
authorised stops working, and after the second refused send the dashboard banner appears and the administrators
are emailed. They reconnect the inbox from **Configuration**, approve the permissions, and the queue of
conversations that arrived during the outage is waiting in the inbox.

## Who can do this

**Administrators** only. Agents see the banner and can keep reading, but Configuration and Account Health are not
open to them — see [roles and permissions](roles-and-permissions).

## Limits

- **Nothing re-sends the messages that failed while the token was invalid.** Retry each one, or send again.
- **Lynomia Chat cannot tell you which permission was lost.** Meta reports a refusal, not a diff.
- **Deleting and recreating the inbox is not the fix** and can release the number from your Meta app. Reconnect
  first.
- **A token you generated by hand will expire again.** The guided sign-up is what avoids repeating this.
