With so many web services using webhooks now, it's getting harder to work with some services without being able to receive the webhooks. Our PXPlus application servers are behind firewalls, and we don't really want to open up ports to receive the webhooks, or manage an entire Apache server outside the firewall instance just to receive the webhook files. We don't need to send webhooks - we just need to receive and store them. I thought about writing a simple receiver (based on the nthost processor) or using EZWeb, but either option probably wouldn't handle the volume of some web API's, and we'd still need to open up ports in the firewall. I started looking into other services to handle this, and have found several apps that will just act as a webhook receiver (for example, Hookdeck).
Anyone out there have any experience/ideas/suggestions for receiving webhooks? I'd appreciate any info you can share before I'm forced to re-invent the wheel!
