I have a Parabola workflow that I would like to run when a column in a Smartsheet sheet is updated. The workflow is working great when I run it manually or on a schedule, but I really want it only to run when an update is made via a webhook. I think I followed the “Create Webhook” steps according to the Smartsheet API, but when I attempt to enable the webhook, I’m see the following error:
Response was missing verification response in both header and body, or body JSON may have been invalid. (ref id: zkrmwoer7oac)
Attached are two screenshots from Postman that illustrate the Create and Update webhook steps I’ve attempted. The “Create” step was successful, but per Smartsheet, you have to “Update” the created webhook to enable it…which is where it seems to be failing. Is this an issue with the Parabola callback URL?
