+ *
+ * ### Notes
+ *
+ * By default, Auth.js assumes that the Paybin provider is
+ * based on the [Open ID Connect](https://openid.net/specs/openid-connect-core-1_0.html) specification.
+ *
+ * The Paybin provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/paybin.ts).
+ * To override the defaults for your use case, check out [customizing a built-in OAuth provider](https://authjs.dev/guides/configuring-oauth-providers).
+ *
+ * ## Help
+ *
+ * If you think you found a bug in the default configuration, you can [open an issue](https://authjs.dev/new/provider-issue).
+ *
+ * Auth.js strictly adheres to the specification and it cannot take responsibility for any deviation from
+ * the spec by the provider. You can open an issue, but if the problem is non-compliance with the spec,
+ * we might not pursue a resolution. You can ask for more help in [Discussions](https://authjs.dev/new/github-discussions).
