I captured an image of what I got after looking for Webhook in IFTTT like it says in the manual… but I can not figure out which one I should use….
Obtain IFTTT Key: go to ifttt.com, sign up for an account. At the top click ‘Search’ to find Webhook, then follow instructions to create aWebhook service. Click on the gears icon on the top-right of Webhook to view your key. Copy this key to OpenSprinkler’s IFTTT key setting.
