Hi @isaacbg84. The webhook URL must be from one of the domains listed in the dialog. The reason the button is disabled is because you are attempting to use a service that is not supported by Arduino Cloud.
Ok would be nice a feature to send json to any place. ll Se what i can do with those services.
By the way make.com has a cool integration with Arduino API. Is there a way to know when a thing changes or gets updated with the API? I could make a periodic call i suppose.
Unfortunately I'm not familiar with Make. Maybe one of the other forum helpers is knowledgeable in this subject matter and will be able to answer that question.
