Parsing a six digit number from a text and sending back to sender?

[dkhu...@gmail.com]

Hi, total noob here trying to get an idea if I am able to do this with the Automate app. 

I receive multifactor authentication texts that require me to text back a number, that is given in the sent text, so that I am able to login. 

The sender number is one of those five digits numbers and is not always the same. However, the number I need to text back is always a six digit number. 

So what I was thinking was if it would be possible for the flow to check if there is a six digit number within the text. If so, then take that number and send it back to the sender. If there is no six digit number, then don't do anything.  

thanks in advance for your thoughts and help!

1. SMS received; (output variable) message: msg
2. Variable set; variable: num, value: matches(msg, ".*(\\d\{6}).*")[1]
3. Expression true; expression= num
4. SMS send; (input argument) message= num

Thank you Henrik!

It's getting an error on the SMS send. Looks like it needs the phone number, which is whoever the original sender is.
And I should also mention that the text also contains text in addition to the six digit number. Not sure if that matters or not with what you gave me.

Here is the log.

Assign a variable name, e.g. pn, to the "Sender phone number" output variable of the SMS received block, then use is as input variable in the SMS send block.

Thanks! That fixed the error, but looks like it is stopping at the expression and the text isn't being sent out. Not sure if there is a way for me to attach the .flo here.
