How to Set Default Country Code to +1 for Phone Numbers in Cal.com via API

[SebasQuintero17]

Hello, I’m trying to configure the default country code for phone numbers to '+1' in Cal.com forms using the API or app settings. Does anyone know the best way to implement this or have any documentation to reference? Thank you!

Hey @SebasQuintero17! I'm here to help you with any bugs, questions, or contributions you might have for Cal.com. Let's tackle this together!

To set a default country code for phone numbers in Cal.com, you can use the useDefaultCountry hook. This hook initially sets the default country to "us" and attempts to update it based on the user's country code obtained from the trpc.viewer.public.countryCode.useQuery. If the country code is supported, it sets it as the default; otherwise, it defaults to "us" ^[1].

If you want to ensure the default country code is always set to "+1", you might need to customize this behavior in your application settings or configuration files. Unfortunately, there isn't specific documentation available for setting this via the API, but you can explore the codebase to see how the useDefaultCountry hook is implemented and adjust it to suit your needs.
