In azure automation, when you define a webhook for a runbook the headers of the request are passed to the runbook via the WEBHOOKDATA input parameter. For python workbooks, the parameter is passed as first argument to the script.
For example, here is a runbook:
import json
import sys
print(sys.argv)
if len(sys.argv) > 1 :
test = json.loads(sys.argv[1])
print(test)
Here is the input parameter WEBHOOKDATA
{"WebhookName":"python-Test-Arguments","RequestBody":"","RequestHeader":{"Cache-Control":"no-cache","Connection":"keep-alive","Accept":"*/*","Accept-Encoding":"gzip","Host":"s2events.azure-automation.net","User-Agent":"PostmanRuntime/7.1.1","action":"myaction","Postman-Token":"312ce179-d2d1-4b5d-935c-d801fc0ba114","x-ms-request-id":"e6b3a5e3-17b3-4d2a-a00c-a1be928acca2"}}
The output (basically print(sys.argv))
['C:\\Temp\\yjzgss3j.git\\caf4e30b-0cb1-4c60-9e93-e2315b376634', '{WebhookName:python-Test-Arguments,RequestBody:",RequestHeader:{Cache-Control:no-cache,Connection:keep-alive,Accept:*/*,Accept-Encoding:gzip,Host:s2events.azure-automation.net,User-Agent:PostmanRuntime/7.1.1,action:myaction,Postman-Token:312ce179-d2d1-4b5d-935c-d801fc0ba114,x-ms-request-id:e6b3a5e3-17b3-4d2a-a00c-a1be928acca2}}']
json.loads fails
Traceback (most recent call last): File "C:\Temp\yjzgss3j.git\caf4e30b-0cb1-4c60-9e93-e2315b376634",

The JSON syntax looks correct to me. Might be something related to encoding, or how Azure automation pass the parameters to runbook.
