NewMailgun - publicApiKey

[EtienneBruines]

I suppose the function

func NewMailgun(domain, apiKey, publicApiKey string) Mailgun {
    m := MailgunImpl{domain: domain, apiKey: apiKey, publicApiKey: publicApiKey}
    return &m
}

has a publicApiKey because the API v2 uses it? I cannot find any reference to it at the documentation / website of Mailgun, and leaving it blank enables me to send the e-mail anyway.

What's its use? And why is it still there?

Have a look at the documentation here. The advice for these types of API calls is to use the public API key.

Same here, very confusing. So where is the public API key? I can't find that in my admin interface either.

This issue has been resolved. The public API key is used when validating email addresses. Please see the documentation linked. It seems that the public API key is linked to the account and not the domains - it can be seen on the dashboard right hand side (currently).
