Integration with Bubble.io

Hello, i am making an integration by webhooks with Bubble.io. I use the custum integration.
In the live data i receive an error message: …,status code 404 \status\ NOT FOUND message:
Workflow xxxx not in initialization mode.. why is that? Can you help me?
Best regards

i ALL, Now i found the solution : Bubble.io puts “initialize” at the end of the URL, we have to take that off in the integration.

bet regards

Once you have a nice example running, can you create a write-up for others to use?

Sure, after i have a good graphical interface will put here a link that all can see, but i use Bubble.io to make my application server. I have 2 self made devices (distance and temperature/humidity) connected to TTN Lorawan Server. In my console i choosed webhooks integration and custom template.
In Bubble.io i use Backends workflow to create my webhook “receiver”. Bubble.io creates a URL that ends in \initialize, this as to be taked off when create the webhook in TTN. In small words thats it.
