Retrieves and caches the Ed25519 public key used to verify Telnyx webhook signatures.

Installation

dotnet add package Soenneker.Telnyx.PublicKeys

Registration

using Soenneker.Telnyx.PublicKeys.Registrars;

services.AddTelnyxPublicKeysUtilAsSingleton();

Singleton registration shares the cached key across consumers. Use AddTelnyxPublicKeysUtilAsScoped() when the utility should follow the current scope; its Telnyx HTTP provider remains singleton and is reused across scopes.

Configure the Telnyx API token used to retrieve the account's webhook-signing key:

{
  "Telnyx": {
    "Token": "KEY..."
  }
}

Usage

using Soenneker.Telnyx.PublicKeys.Abstract;

public sealed class WebhookService
{
    private readonly ITelnyxPublicKeysUtil _publicKeys;

    public WebhookService(ITelnyxPublicKeysUtil publicKeys)
    {
        _publicKeys = publicKeys;
    }

    public async ValueTask<string> GetPublicKey(CancellationToken cancellationToken)
    {
        return await _publicKeys.Get(cancellationToken);
    }
}

Get() retrieves the Base64-encoded Ed25519 key from Telnyx and caches it for 24 hours. Use Refresh() when you need to bypass that cache immediately.

RefreshIfCurrent() supports signature-verification retry flows. It refreshes only when the caller's key is still current and rate-limits conditional refreshes to one per minute.
