Why am I getting error code 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:
– Carousel templates
– Catalog button templates
– Coupon code templates
– Multi-product button templates
– Voice call button templates
– Order details button templates
– Limited time offer templates
– Interactive messages with CTA URL buttons
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.
4. Contact Support
