Why am I getting error 7021 – EC_LIMITED_FUNCTIONALITY?

Error code 7021 – EC_LIMITED_FUNCTIONALITY appears when unsupported features are used in message requests, most commonly by on-premise senders. This typically happens when attempting to send template messages that are not supported in the on-premise environment, such as carousel messages or certain interactive buttons.

Why it occurs

This error signals that the message request includes features not supported in the current sending environment. On-premise WhatsApp setups usually have limited support for some advanced or interactive message formats.

Common unsupported features include:

Steps to resolve the issue

1. Verify the sender environment


– Confirm whether the sender is operating in an on-premise setup.
– Identify any features in use that may not be supported in that environment.

2. Adjust message features

– Replace unsupported elements (e.g., carousel templates) with alternative message formats.
– Reconfigure your message request to match the supported features of your current environment.

3. Consider a cloud-based setup

If you require access to advanced features, explore migrating from an on-premise setup to a cloud-based configuration, which typically supports a wider range of interactive message formats.
