  1. Set / Update Trigger: Enter the webhook URL and click the "Yes" button to set the trigger. Optionally set the last column name which when filled will trigger and send the row.

  Input examples:-
  a. Webhook URL only: https://connect.pabbly.com/workflow/sendwebhookdata/IjU33
  b. Webhook & last column: https://connect.pabbly.com/workflow/sendwebhookdata/IjU33, D
  (Assuming D is the last column to be sent. The new row will only be sent if there is data in the Column D. Webhook URL and the last column name should be separated by a comma.)

  2. Remove Existing Trigger: Click the "No" button if you wish to remove the trigger you set earlier.
