It’s always good to test Webhooks in an external or temporary environment before making changes in production.

RequestBin is one such tool to test your Webhooks

RequestBin gives you a URL that will collect requests made to it and let you inspect them in a human-friendly way. To get started, go to, check the box next to “Private (only viewable from this browser),” then click the “Create a RequestBin” button.

Next, copy the bin URL they provide and enter that as your Webhook URL in Netcore email API.
