Disable Post Creation During Ajax Submission?

Hi.

New GF user, first post here.

Sorry, I have two questions in this one topic post, though they are closely related, so I'll risk asking them both at once. :-)

1.) It seems that the filter 'gform_disable_post_creation' is only applicable within standard (non-ajax) submissions. Is that correct?

If so, is there some other way to bypass creation of a form submission entry post when the submission method is via ajax?

2.) I'm feeding the entry data to a third-party application. It seems that ajax submissions do not flow through the 'gform_post_submission' hook. Is that correct?

I am successfully using the 'gform_confirmation_loaded' hook by chaining to another custom ajax jQuery.post(), at the "expense" of a GF entry post each time. (Tolerable, but undesirable). :-)

Is there some other way to "hook" into the entry (data) in order to continue-on to a third-party application when using ajax?

Thanks!
