How Can I Fix the 'Preferred locale is not enabled' API Error?

When submitting a request such as "Create Account" through the Recurly API, this error message can be returned. It is caused by the language setting in your email configuration not being set up to accept the language that is being sent by the request. Specifically, this happens when the preferred_locale field is set to a value that is not enabled for your site.

To resolve this, you can do one of the following:

• Add the preferred_locale you are trying to submit to your email template settings. You can find these settings in the Recurly Admin Console.

• Submit the API request with a value for preferred_locale that is already accepted in your email template settings.
