I have a question for the community here since I could not find a clear answer in the Twilio's docs.
Basically I've setup a Messaging Service and specified a status callback url:
[![enter image description here](https://i.stack.imgur.com/5I9m3.png)](https://i.stack.imgur.com/5I9m3.png)

Will Twilio POST do this url in a synchronous manner? Is it safe to assume that consecutive calls to this url will happen only after a previous request is anwsered by my server?

I'm afraid of a race condition here - that the first POST could be handled 
 after the second one and I could update the message in my db with an outdated status.
