'ContactNotFoundException' while using "StopContact" API for the 'Callback Contact"

Question

While trying to use the "StopContact" method I'm getting this exception, I verified the Contact ID is valid, actually the document is confusing so not sure if "StopContact" API supports queued callback,

As per the error description:
Ref: https://docs.aws.amazon.com/connect/latest/APIReference/API_StopContact.html#:~:text=to%20Chat%2C%20Task%2C-,or%20Voice%20Callback.,-HTTP%20Status%20Code
**ContactNotFoundException**
The contact with the specified ID is not active or does not exist. Applies to Voice calls only, not to Chat, Task, or **Voice Callback**.
HTTP Status Code: 410

Also there is one article which says **Stop Contact** now supports **Callback**
https://aws.amazon.com/about-aws/whats-new/2022/05/amazon-connect-launches-api-to-programmatically-stop-queued-callbacks/

So can you confirm if it supports queued callback contacts,

Answer

If you enable Amazon Connect contact events* what does the contact ID value show for the call once it's set for callback?

Answer

It definitely supports callbacks.  Two questions:

1. How are you creating the callback?
2. How are you getting the Contact ID for the callback?
