<p>
ClientToken is an idempotency token that ensures a call to <code>DeleteProject</code> completes only once. You
choose the value to pass. For example, An issue might prevent you from getting a response from
<code>DeleteProject</code>. In this case, safely retry your call to <code>DeleteProject</code> by using the same
<code>ClientToken</code> parameter value.
</p>
<p>
If you don't supply a value for <code>ClientToken</code>, the AWS SDK you are using inserts a value for you. This
prevents retries after a network error from making multiple project deletion requests. You'll need to provide
your own value for other use cases.
</p>
<p>
An error occurs if the other input parameters are not the same as in the first request. Using a different value
for <code>ClientToken</code> is considered a new call to <code>DeleteProject</code>. An idempotency token is
active for 8 hours.
