Participant Update - Country, Region and City

 To modify the Country, Region and city associated with an existing account, employ the /api/v2/account/set endpoint. To modify a specific visitor, identify them using one of EP's accepted matching methods and employ the subsequent fields:

• event_id: The unique identifier for the event. (integer)

• id: Account ID (integer)

• country: Account Country (ISO2)

• region: Account Region (ISO2)

• city: Account City (string)

It is permissible to add or modify a country that is not currently listed. Countries, regions, and cities will only be displayed and accepted if they have been previously configured in Event Setup > Country Manager. Within this section, it is possible to add, modify or delete countries, regions, and cities.

Notice: Mandatory inclusion of the country parameter is prerequisite for saving a region, and the region parameter is prerequisite for saving the cities.
