Looking at the directions to set up notify help a lot, but I don't need to notify a user that an interaction was created.  I already have Twilio sending and email with a link to voice message and a transcription of said voicemail.  I'm just looking to have Twilio send data to SN so I can create an interaction record.  Most probably for reporting purposes.  I'm still deciding where to post the data (short description, create a field with value choices to use, etc).   feel like I should be able to use the widget called: "Make HTTP Request" and has these fields to fill in:

I can't figure out what url to use in order to trigger a flow to have a record created on the interactions table .

I hope this makes sense.
