CreateOrUpdateWebhookSignatureKey

Create a webhook signature key and set its activation state. If a webhook signature key is active, the bodies of all webhooks will be signed using the signature key with HMAC-SHA-256.The signature generated will then included in the `X-Sift-Signature` HTTP header. Only one key can be held per organization. If an existing key exists, then this will simply return it.See `WebhookService_RotateWebhookSignatureKey` to rotate the key.
