Custom Workflow Actions - Automation API help with API response

[xtractor]

Hi there,

I've only recently started using HubSpot, and have been familairising myself with the custom functions available. 

I've come unstuck with regard to processing API responses via a Customer Workflow Action, and the documentation doesn't give any real examples or pointers to help.

I have a workflow set up and have managed to POST custom API calls without any issues, using data from HubSpot .

However, two issues I have having.

1 - authenicated the call to the API - unclear how this is set (might be a rookie error in the PRE_ACTION_EXECUTION but I did try adding httpHeaders there but that stopped the API call happening at all

2 - taking data form the response for use within HubSpot  

I also could not get the API endpoint 

/automation/v4/actions/{appId}/{definitionId}/functions/{functionType}

to work, it kept gives me a 415 (unsupported media) regardless of what I sent into it. One further point was around outputFieldLabels - these are always lost after creating the custom action, and no examples include them to cross check I've got it right.

Any help on this would be very welcome, as I don't feel the documentation gives enough detail, nor decent examples in order to achieve what I'm trying to do. I'm using beeceptor.com to check what is being sent, and to ensure a senisible payload is returned (that includes client_ip)

Many thanks in advance,

Dave
