Hi, We've done a lot with webhooks subscriptions, if you have any specific questions please let me know. I can confirm it works over both http and https, you should have valid https certificates. URL; '/attask/eventsubscription/api/v1/subscriptions' what object do you want to subscribe to? objCode; Assignment ASSGN Company CMPY Dashboard PTLTAB Document DOCU Expense EXPNS Hour HOUR Issue OPTASK Note NOTE Portfolio PORT Program PRGM Project PROJ Report PTLSEC Task TASK Template TMPL Timesheet TSHET User USER Event type you want to have fire call back. eventType; all, create, update, delete Form Body URL;Your address for the call back. Auth Token; Your own token, workfront will send this in the header to your response, this way you can verify it's legitimate call. Basically to register a subscription create a post form in your language choice. $formBody = array(); $formBody['objCode'] = $objCode; $formBody['eventType'] = $eventType; $formBody['url'] = $url; $formBody['authToken'] = $subscriptionAuthToken; With subscriptions you can not just send your API key in the form or url like most calls. You need to send it as part of the header.
