When working with the WhatsApp Business API, Error Code 3 with a 500 Internal Server Error indicates a capability or permissions issue. This error usually means your app lacks the necessary permissions for the API endpoint being accessed.
What is Error Code 3?
Error Code 3 signifies that the app is facing restrictions due to missing permissions. The server response shows a 500 Internal Server Error, meaning the issue is within the application’s configuration rather than the server.
Solution for Error Code 3
To resolve this error:
Go to the Access Token Debugger and paste your access token. 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.
Add the permissions: whatsapp_business_management and whatsapp_business_messaging (step-by-step guide ahead).
To Generate a New System User Access Token:
Log into Meta Business Suite.
Choose your business account from the top-left dropdown, then click the Settings (gear) icon.
Go to Business settings.
Click User > System users.
Find and select the system user you need from the list.
Click Generate new token.
Select the Meta app you are using for API calls.
Select the necessary Graph API permissions for the app. Ensure whatsapp_business_management and whatsapp_business_messaging are added.
Finally generate the token.
