When submitting a request to the onboarding API, you must provide the country_code using the ISO 3166-1 alpha-2 format.
This means the value should be a two-letter country code, not a numeric dialing code.
For example:
-
US- United States -
GB- United Kingdom -
IN- India
Do not use international dialing codes, such as:
-
+44 -
+1 -
+91
These formats are not supported and will result in validation errors.
