Based on a quick Google search, I’m pretty sure this method requires the third-party API’s web server to support using this method, as it doesn’t appear to be enabled by default. I’ve been looking into various ways to be able to perform other http requests, and have tried to use X-Http-Method-Override in the past with only little success. Either I’m doing it wrong (which could be entirely possible, but doubt it since its fairly easy), or Servers aren’t configured to support it by default, thus why I request ROBLOX to support adding this feature on another thread: Table HttpService:RequestAsync(table request)
I really like the idea of having a “table” which we can build the request on, and I think would improve ROBLOX games drastically by allowing them to be able to integrate third-party services by being able to properly interface with them.
