This API is for Telco or external payment methods, not generally for In App Payments. It returns the plans linked to the user's country based on their IP address. If no plans are found for this country, then the API would return all plans linked to the clients home country. The use case would be that you want to display an alternative subscription option for users of a single country but maintain a standard for the rest of the world. Note: The data for this API must be configured for the specific service, otherwise you should not use this API.
