## Resolving WhatsApp Business API Error Code 10: Permission Denied

When using the WhatsApp Business API, **Error Code 10** (Permission Denied) with a **403 Forbidden status** indicates that the necessary permissions are either missing or have been removed. This error usually prevents access to certain API endpoints or actions.

## What Causes Error Code 10?

Error Code 10 means that permission for the requested action is either:

- Not granted to the app.

- Removed from the app’s access.


## **Solution for Error Code 10**

To fix this error, follow these steps:

1. Go to the [Access Token Debugger](https://developers.facebook.com/tools/debug/accesstoken/) and paste your access token to check if your app has the required permissions.


- Verify if the required permissions, **whatsapp\_business\_management and whatsapp\_business\_messaging**, are enabled.

- If your token doesn’t include these permissions, you’ll need to create a new one. While generating the token, make sure to select the Meta app you are using for API calls and to add the permissions: whatsapp\_business\_management and whatsapp\_business\_messaging (detailed steps ahead).

2. Ensure that the phone number used to set the business public key is allowlisted.

### To Generate a New System User Access Token:

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. Select the **Meta app** you are using for API calls.

8. Select the necessary **Graph API permissions** for the app. Ensure **whatsapp\_business\_management** and **whatsapp\_business\_messaging** are added.

9. Finally generate the token.


By confirming the necessary permissions and allowlisting the required phone number, you can restore access and resolve Error Code 10.
