Chatlayer ResponseBuilder

Hi Community,

For a voicebot in Chatlayer I need to strip characters from an input, when asked e.g. a customer number. When the input is "Yes, my number is 123456" I only want to capture the 123456. I tried with a regex in an collect input block and store the value in a variable, but that does not work.
Secondly I tried to use the initial input variable and use the Action Block with a Code action to code a ResponseBuilder as described in https://docs.chatlayer.ai/integrateandcode/code-action

Here I am trying to use the initial variable, use a regex to clean up the input and store the output it in a second variable. This would then be digits only.

Has anyone solved this or has any other way of cleaning an input?

Thanks!

Hi Shahzad,

I asked internally some coders and they came up with this working solution:

First I collect input in a variable {Cust_ID}

then I use the Action node with a code action. I assign as argument a new variable CustID with value of Cust_ID.

Then I was given this code:

let ID = args.CustID

ChatlayerResponseBuilder()

.addSessionVariable("Cust_ID2", ID.replace(/\D/g, ''))

.send();

Result was variable Cust_ID2 was populated with the stripped digits from Variable Cust_ID.

In a message node I output the value of variable Cust_ID2 with

<speak>
So your customer number is:

<break time="1s"/>

<say-as interpret-as="characters">{Cust_ID2}</say-as>
</speak>

for the user to confirm with yes or no before proceeding.

This is a working solution, but when you have better ideas, I'd love to hear them.

Thanks!

Edwin.
