We are currently debugging a persistent 404 Not Found error when attempting to register event subscriptions via the Platform API (/api/v2/architect/webhooks) within our AppFoundry partner application. Our integration serves multiple Genesys Cloud organizations and relies heavily on real-time event streaming for contact center analytics.
The issue manifests specifically when the webhook endpoint is hosted on a subdomain that requires mutual TLS (mTLS) authentication. While the initial POST request to create the subscription succeeds with a 201 Created status, subsequent test events sent by Genesys Cloud fail to reach our endpoint. The Genesys Cloud event log indicates a 404 response, despite our server logs showing no incoming traffic during these test windows.
We have verified that the webhook URL is publicly accessible and that the mTLS certificate is valid and trusted. The problem appears to be isolated to the multi-tenant context where the OAuth scope includes org:webhooks:write but the underlying network configuration varies across customer environments. We suspect that the Genesys Cloud event delivery service may not be correctly handling the TLS handshake for endpoints behind certain load balancers or that there is a mismatch in the certificate validation process.
Has anyone encountered similar issues with webhook delivery failures in a multi-tenant AppFoundry setup? We are using the latest version of the Genesys Cloud SDK for Node.js and have confirmed that the API rate limits are not being exceeded. Any insights into the expected behavior of the webhook delivery service regarding mTLS endpoints would be greatly appreciated.
I deal with automated deployments and CI/CD pipelines for Genesys Cloud integrations. A 404 on webhook registration usually means the platform cannot verify the endpoint, not that the resource is missing. When using mTLS, the standard HTTP POST to /api/v2/architect/webhooks often fails because the Genesys Cloud backend performs a verification challenge (GET request with a specific header) before finalizing the subscription. If your load balancer or API gateway drops this challenge due to mTLS handshake issues or missing certificates, you get a 404 or a generic connection error.
Check your Terraform configuration for the genesyscloud_routing_webhook or genesyscloud_platform_event_subscription. Ensure you are not only setting the URL but also handling the certificate validation correctly.
resource "genesyscloud_platform_event_subscription" "analytics_feed" {
name = "mtls_analytics_feed"
description = "Real-time analytics via mTLS"
event_types = ["contactCenter.queueStats"]
webhook {
url = "https://analytics.subdomain.example.com/webhook"
# Ensure the certificate is valid and trusted by Genesys Cloud
# mTLS requires the server cert to be signed by a public CA or
# uploaded to the Genesys Cloud certificate store if private.
retry_interval = 300
max_retries = 5
}
}
Verify the endpoint responds to a simple GET request with the Genesys-Webhook-Verification header. If you are using AppFoundry, ensure the partner application has the correct permissions to write to the target organization’s webhook settings. Also, check if the subdomain firewall is blocking the Genesys Cloud IP ranges during the verification phase. Use the CLI genesyscloud platform event subscription get to inspect the current status and error codes.
The 404 you are seeing is likely not a standard HTTP not-found, but rather a failure in the handshake validation phase. Genesys Cloud does not simply POST to your endpoint; it issues a verification GET request to ensure the endpoint is reachable and secure before committing the subscription. If your AppFoundry application is handling mTLS at the application layer rather than the network layer, the verification payload might be malformed or rejected by your ingress controller, resulting in a 404 response from the Genesys perspective.
I suggest bypassing the direct webhook registration for mTLS endpoints and instead using a Data Action as an intermediary. This approach aligns better with robust ServiceNow integration patterns I have deployed. Configure a Data Action in Genesys Cloud that accepts the event payload, then use the built-in HTTP client within the Data Action to POST to your ServiceNow REST API endpoint. This shifts the mTLS complexity to your ServiceNow side, where you can manage certificate pinning and authentication headers explicitly in the request configuration.
Here is a conceptual flow for the Data Action:
- Input: Event payload from Genesys.
- Logic: Transform JSON to match ServiceNow Incident table schema.
- Output: HTTP POST to
https://[your-instance].service-now.com/api/now/table/incident.
This method also provides better error handling. If the ServiceNow endpoint is down, the Data Action can log the failure to a Genesys Data Table for retry logic, whereas a direct webhook failure often results in silent drops or complex retry loops on the Genesys side. Check the “Data Actions” section in the Genesys docs for the HTTP client configuration details. This pattern is significantly more reliable for multi-tenant scenarios where certificate management varies across environments.
