Webhook

Hi!

Client asks to develope an integration with external system. This system generates a documents and sends them as a set of metadata and file in base64 format in POST query. So ot is assumes that we have to use webhook in M-Files for receive and process these queries. I found this document about webhooks functionality in M-Files: m-files.my.site.com/.../mfiles-ka-412465 . But this is all the information I was able to find about this. Is there some additional info about how to set up and use webhooks in M-Files? Is this possible to use it for receive POST queries with predefined structure (including base64 file)?

Or maybe someone tried to create his own webhooks inside of vault application app? I guess it should be creation of HTTP server using HTTPListener or smth like this.

Thank you!
