VK

Get your VK ID credentials

To use VK ID sign in, you need a client ID and client secret. You can get them from the VK ID Developer Portal.

Make sure to set the redirect URL to http://localhost:3000/api/auth/callback/vk for local development. For production, you should set it to the URL of your application. If you change the base path of the auth routes, you should update the redirect URL accordingly.

Configure the provider

To configure the provider, you need to import the provider and pass it to the social_providers option of the auth instance.

require "better_auth"

auth = BetterAuth.auth(
secret: ENV.fetch("BETTER_AUTH_SECRET"),
base_url: ENV.fetch("BETTER_AUTH_URL", "http://localhost:3000"),
social_providers: {
vk: BetterAuth::SocialProviders.vk(
  client_id: ENV.fetch("VK_CLIENT_ID"),
  client_secret: ENV.fetch("VK_CLIENT_SECRET")
)
}
)

Sign In with VK

To sign in with VK, call auth.api.sign_in_social on your Ruby auth instance. The endpoint body takes the following properties:

• provider: The provider to use. It should be set to vk.

response = auth.api.sign_in_social(
body: {
provider: "vk",
callback_url: "/dashboard",
error_callback_url: "/login",
disable_redirect: true
}
)

redirect_url = response.fetch(:url)
