Error: Twilio Error 20003

What's Causing This Error?

The error 20003 means "Permission Denied", indicating that you lack permission to access the requested resource. That is likely to happen:

• If you use the wrong combination of Auth Token and account SID.
• If attempted to access the master account with credentials of a sub-account.
• If attempted to access Live Account from Test credentials.
• If the API Key gets deleted.
• If the Auth Token gets deleted.

Solution - Here's How To Resolve It

To solve this issue, you can:

• Check whether JWT is used only with the API Key and not with the Auth Token.
• Verify that you are attempting to access the correct account.
• Verify that the account SID and Auth Token are accurate and valid.
• Check whether the account is active and not suspended.
