get entry_id on submission

Hi,

is there any way to get the entry_id within the action af/form/submission/?

Or will I have to get it by ‘af/form/entry_created?

If it works only after entry_created, how will I get the field values of the entry?
In ACF style it should be like $fieldvar = af_get_field(‘FIELDNAME’, $entry_id).

Thank you in advance.
Sebastian
