I see in my space log the following entry:
The hard limit of 30 for creating entities of type 'Webhook Listener' has been reached.
What does this mean?
This means that you are not allowed to create more webhook listners. This can happen if you have mutliple shopping carts linked with your space. One solution is to reduce the number of webhook listeners you are using or you may want to request a limit increasing in by our support.
