Webhook n00b question: parameterValue format? So, I'm playing around using the HTTP module to create webhooks which do things I can't do by using the Watch Events module. I was able to make a filter with an OR statement, which is wonderful. Ultimately though, I want to have a webhook where the newState of a custom form field is different than oldState thereof. I used this, got a 201, but it doesn't seem to work: {"objCode": "DOCU","eventType": "UPDATE","url": "https://hook.app.workfrontfusion.com/liw3gfiixg6aepx3xr2371ugqkavf48l","filters": [{"fieldName": "DE:What version of legal and compliance review is this?","fieldValue": "","comparison": "changed"}]} Please tell me there's something stupid I'm missing here. There has to be.
