How do I select the first element in a multi-element array?

Attached is an example of data returned from a phone number lookup.

How would I select the first entry [0].

What would the rule group be for this also what is the purpose of a rule group?

<Rule Type="Any">customerList.customerId</Rule>

It should detect the array and match with this. That's how it knows it has results.

Then, set the path for your variable to the same kind. 3CX should take care of grabbing the array element.

I can get some results using customerList.customer.customerId as the rule but am unable to access a value that's path is customerList.customer.addresses.phoneNumber2 even though I can create a variable and output from the results.

The only way to select a specific element in an array is using filters. You can check the template we provide for Bitrix to understand how we use this. Also, here you have details of the XML required for that:
