Messaging integration webhook validation stuck on 409 Conflict during apply

General Discussion

genesys-cloud-sdk throws a 409 Conflict when the provider attempts to validate the inbound webhook for genesys_cloud_messaging_integration. The state file shows webhook_validation_status stuck on PENDING, which kills the plan phase because the resource won’t move past creation. URL is whitelisted in org settings, yet the API keeps timing out on the callback check. Terraform version 1.7.4, provider 1.28.0. Flow looks fine, but the messaging engine rejects the signature before the state locks. This broke the staging deployment for two hours while the queue backlog grew. Doing jack all on the network side, ports are open. POST /api/v2/messaging/integrations returns {"code":"conflict","message":"Validation failed"} repeatedly. The validation_token isn’t matching what the SDK expects, even though the secret is correct. Mic stays hot on the debugging session.

resource "genesys_cloud_messaging_integration" "fb_test" {
 name = "FB-Test-Channel"
 type = "facebook"
 webhook_url = "https://hooks.mybpo.internal/gc-msg"
 status = "ACTIVE"
}

Skip the provider auto-validation check and force the state to VALIDATED using a lifecycle ignore. The callback timeout usually happens when the messaging engine retries against a restricted subnet. That delay breaks the MiFID II and Dodd-Frank message transcription retention pipelines.

resource "genesys_cloud_messaging_integration" "compliance_channel" {
 name = "Regulated-Support"
 web_address = "https://hooks.example.com/genesys"
 
 lifecycle {
 ignore_changes = [webhook_validation_status]
 }
}

A manual trigger works better once the flow deploys. Hit POST /api/v2/messaging/integrations/{id}/validate with a basic auth header matching the org settings. The workaround posted earlier covers the subnet routing, but it misses the retention gap. If the webhook stays pending, the secure pause and legal hold triggers won’t fire on inbound SMS. Regulators expect a continuous audit trail, and a stuck status drops half the interaction metadata. Run a quick export test against the compliance bucket after the manual POST. Check the recording_status field on the first three messages. The validation usually hangs for ages. If it shows SECURE_PAUSE_PENDING, the flow architecture needs a fallback queue entry.
