Business Connector: How to handle errors on HTTP POST

Hi I want to be able to catch errors when I issue a HTTP POST to our partners system. At the moment the service is failing if fx the partners server is down and the document (order) needs to be manually re-posted (restore pipeline functionality... and all over again - not very userfriendly) my a user.

How to catch these errors and resend automatically? Help will be greatly appreciated. :wink:

Thx in advance
