Multiple Choice

While working with the Webex Teams API, on an application that uses end-to-end encryption, a webhook has been received. What must be considered to read the message?

A) Webhook information cannot be used to read the message because of end-to-end encryption. The API key is needed to decrypt the message.
B) Webhook returns the full unencrypted message. Only the body is needed to query the API.
C) Webhook returns a hashed version of the message that must be unhashed with the API key.
D) Webhook returns message identification. To query, the API is needed for that message to get the decrypted information.
