I have an API which I would like to consume to do specific actions on my Drupal 7 website after getting data from the user via a webform form. I plan to write my own custom module to do that but don't know how where I should start from.
Is there any hook that could help me add supplementary action after getting data from my webform ? How am I supposed to proceed to consume my web services ? Any code snippet, advice, will be appreciated.
