Also, once you extract the data (i.e card number, expiration date) using the text functions mentioned above , it is a good idea if you check the length of the card number (some sort of validation) to make sure you are always grabbing the correct digits.

Awesome! That's a good starting point.

As mike suggested you can use code like below

load(
local!data: split(
"BBVA
Rewards
4000 1234 5678 9010
12/20
VALID
THRU
VISA
JOSE MARIA SANCHEZ",
char(
10
)
),
{
cardNumber: local!data[3],
name: local!data[8]
}
)

Two suggestions for a start:

1) if the API call will always return data in the exact same format (i.e. always the same number of lines where the same line always has the same info, line 3 = card number, etc) -- use the split() function like split(local!returnText, char(10)), which will give you an array where the credit card number is local!array[3] and the card holder name will be local!array[8] for example.

2) if there might be a little bit of variability to the number of lines, but the data is at least always in the same order, you could also use the extract() function, which will let you extract, for example, everything between "Rewards" and "VALID", or between "VISA" and the end of the string.
