Creating a payment with Paypal

Hello,

I am a beginner on Make and I am having a problem integrating with Paypal.
I followed the instructions, but I cannot retrieve essential information for STEP 2.

Create a payment (Step 1)
The function works perfectly, I retrieve the following information:
OUTPUT
Bundle 1 : Collection
ID PAYID-M337UOI4419390…
State : created
Payment Intent : sale
Approval URL: https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=**EC-26P120418V9643…**

Execute a payment (Step 2)
Payer ID: I retrieve the information collected on step 1
Payment ID: I cannot find how to extract the payment ID at the end of the URL.

Thank you in advance for your help.
