putKeyword
Creates or updates a keyword configuration on an origination phone number or pool.
A keyword is a word that you can search for on a particular phone number or pool. It is also a specific word or phrase that an end user can send to your number to elicit a response, such as an informational message or a special offer. When your number receives a message that begins with a keyword, Amazon Pinpoint responds with a customizable message.
If you specify a keyword that isn't valid, an error is returned.
