While using the Kakao Moment variables, there’s a caution part in variable section, Ad creation: Personalized message creative | Kakao Developers Ad creation: Personalized message creative

I am wondering if there’s more detail guide for using kakao variables?
For example, is there any content validation on URL strings?

Also, for data types of variable, is there more specific descriptions on “String”, “Number”?
Is the number a signed 16bit integer? and the length of the number is the digits that can be shown?

Best regards,

Hello. I am the Kakao Moment API operator.

Q1.
I am wondering if there’s more detail guide for using kakao variables?
For example, is there any content validation on URL strings?

→ The type and maximum number of characters are checked, and the URL is checked by regular expression matching.

Q2.
Also, for data types of variable, is there more specific descriptions on “String”, “Number”?
Is the number a signed 16bit integer? and the length of the number is the digits that can be shown?

→ ex> priceAmount (String)
Price for CAROUSEL_COMMERCE_MESSAGE
(Minumum: 0, Maximum: 99999999, integers only)
Required for CAROUSEL_COMMERCE_MESSAGE
However, when using a variable, up to 100 characters are allowed.
The convert result must meet the guideline.

→ If the currency information is Korean Won (KRW) or Yen (¥), only integers (0 to 99999999) of 8 digits or less can be entered
