In the WhatsApp Business API, **Error Code 190** indicates that your access token has expired, resulting in a **401 Unauthorized** status. This error prevents API access until a new token is generated.

## What Causes Error Code 190?

Error Code 190 appears when the access token has reached its expiration date, meaning the app can no longer authenticate requests using that token.

## Solution for Error Code 190

To resolve this error, generate a new system user token by following these steps:

1. Log into **[Meta Business Suite](https://en-gb.facebook.com/business/tools/meta-business-suite)**.

2. Choose your business account from the top-left dropdown, then click the **Settings** (gear) icon.

3. Go to **Business settings**.

4. Click **User > System users**.

5. Find and select the system user you need from the list.

6. Click **Generate new token**.

7. Choose the app that will use the token.

8. Select the necessary **Graph API permissions** for the app, then generate the token.
