Im newbe in n8n. I use version 1.43
I create a simple workflow that send message to telegram by webhook
I press Active toggle for this workflow, but it worked only when Test botton pressed
when Test button is not pressed I see error in brpwser
{“code”:404,“message”:“The requested webhook "f3a8502c-xxxx" is not registered.”,“hint”:“Click the ‘Test workflow’ button on the canvas, then try again. (In test mode, the webhook only works for one call after you click this button)”}
It looks like your topic is missing some important information. Could you provide the following if applicable.
Hi @tolyan_k ,
Welcome to the community! 
Would you be able to share your workflow or a view of the parameters you’re setting in the nodes?
In the meantime, could you check if you have set the correct url to use in active mode?
When inactive/test mode, the webhook node provides a test url, but in active more this changes and the “test” param is removed from the url.
So, when posting something we need to make sure to edit the endpoint url from the test to the production url
Thank you, mariana-na, now all right
I’m so inattentive
