Graph API calls use access tokens for authentication. For more information, see Access Tokens. We recommend using your system user to generate your token.
To generate a system user access token:
- Go to Business Manager > Business Settings > Users > System Users to view the system user you created.
- Click on that user and select Add Assets. This action launches a new window.
- Under Select Asset Type on the left side pane, select Apps. Under Select Assets (in the middle pane), choose the Meta app you want to use (your app must have the correct permissions). Enable Develop App for that app.
- Select Save Changes to save your settings and return to the system user main screen.
- Now you are ready to generate your token. Still on the system user main screen, click Generate Token and, again, select your Meta app. After selecting the app, you see a list of available permissions. Select
whatsapp_business_managementandwhatsapp_business_messagingand click Generate Token. - A new window opens with your system user, assigned app and access token. Save your token.
- Optionally, you can click on your token and see the Token Debugger. In your debugger, you should see the two permissions you have selected. You can also directly paste your token into the Access Token Debugger.
