Is Value a Number or Letter

Is there a Flow action that will determine if a value is a number or letter? 

 

I'm wanting to extract the first value of a string, then perform a certain action if it's a number or letter.
If value = number, then send email to Orange
If value = letter, then send email to Red

Hi @ques0buffet 

 

To get the first character from string use expression

substring(your value,0,1)

 

now to check if it is number or not

if you run expression 

int(substring output)

 

This will succeed if it is an integer else it will throw an error.

You can use configure run after action to check if error.

In case of error - the  first character is a string

In case of success - the first character is a number
