I'm really enjoying CiviCRM (recently upgraded to 4.7.13) and was excited about its SMS capabilities. So far, I have been successful in using CiviSMS with Twilio to schedule/send bulk messages.
But, I cannot yet receive inbound SMS responses in CiviCRM with Twilio. For example, if someone responds to one of our messages, it does not show up as an Activity in CiviCRM.
I followed the instructions for setting up Twilio for inbound SMS, but no inbound SMS arrived in CiviCRM.
Here's my configuration of Twilio in CiviCRM:
In my Twilio logs, you can see my configuration as well as the report on how the HTTP POST is running into a 404 error. Here is the detailed error log from Twilio
I've done a number of things to try and fix this--I disabled security plugins, played around with case of the API info entered in CiviCRM.. and now I've started to look at the htaccess files and permissions. But this kind of tinkering is out of my league, so am stopping before I do any damage.
So, I could use any advice y'all could provide.
