Hello,
mod_httapi appears to be handy alternative to calling embedded language scripts for ad-hoc dialplan interactions.  I can see a lot of potential for this, do many people use it?  If you have used it in production would you share any experiences good or bad?  Any hints or tips or gotchas to avoid?

The reason for me asking this, is that I'm having second thoughts about using Python and I really don't like Lua.


Kind regards,

Adrian Fretwell

When we started with FS years ago, we built everything with mod_xml_curl.


After that we've started with mod_httapi and if we would start over, we would build more logic with mod_httapi. I like it as you can build small pieces of dialplan and have more control of logic while call progress through dialplan. In mod_xml_curl you have to build all dialplan, when call starts, that FS compiles it. You can use transfer, but mod_httapi is more developer friendly.


We are using mod_httapi in production without problems, but still main logic is with mod_xml_curl.


If you are using Python, you can write webhooks in Python or in any language you prefer.


I am also curious how community is using mod_httapi.


BR, Gregor

Hi Gregor,
Thankyou that is really helpful.
I have been using Python with Postgresql behind Nginx to serve mod_xml_curl  and have managed to get the round trip response times down to 3 or 4 milliseconds.  So I figured if I can do the same with handling httapi requests, it should work reasonably well.



Kind regards,

I use mod_v8 with a small script that curl's to my endpoint with instructions.

It's not fully featured, but I've set up what I need.

We are using mod_xml_curl & c/c++ app to handle scripting, logic, ivrs, recording, etc.
New version is go based & httapi.

Both mod_xml_curl and mod_httapi work quite well in production, been using both for years. At some point you will reach a max performance level and will either need to horizontally scale the load by adding more FreeSWITCH boxes and some sort of front end load balancer for the SIP side (OpenSIPS or Kamailio) but this works very well.

Thankyou Ken, 

...and many thanks to all who have replied to me on this, it has been very helpful.
I now have httapi up and running on the test bed with a low latency web server and it works very well.



Kind regards,

Adrian Fretwell
