Digital Channel Integration Failure: 400 Bad Request on Webchat Widget Config

General Discussion
1

Stuck on deploying a custom webchat widget configuration via Terraform. The deployment pipeline fails at the genesyscloud_widget resource creation step. The error indicates a mismatch in the OAuth client configuration, but the client ID and secret are correctly referenced from the Vault secrets manager.

Environment details:

  • Genesys Cloud Region: au02
  • Terraform Provider: genesyscloud v1.45.2
  • Module: custom-webchat-integration
  • Deployment Stage: Staging

The HCL configuration for the widget is minimal, focusing on the branding and channel settings. However, the API response suggests the underlying digital channel (webchat) is not properly linked to the OAuth client defined in the genesyscloud_oauth_client resource.

Error: API returned 400 Bad Request

 with module.webchat.genesyscloud_widget.webchat_widget,
 on modules/webchat/main.tf line 15, in resource "genesyscloud_widget" "webchat_widget":
 15: resource "genesyscloud_widget" "webchat_widget" {

Error body: {"errors":[{"code":"invalid_request","message":"The provided OAuth client ID does not have permission to access the specified digital channel."}]}

I have verified that the genesyscloud_oauth_client resource has the digital:webchat:read and digital:webchat:write scopes assigned. The client ID is active and not rotated recently. The digital channel ID is correct and matches the one created in the genesyscloud_messaging_application resource.

Is there a known delay in propagating OAuth permissions to the widget configuration API? Or is there a specific attribute in the widget resource that requires explicit channel binding that is missing in the current provider version? The documentation does not mention any dependency on the OAuth client’s active status beyond the initial creation.

Any insights on resolving this 400 error would be appreciated. The deployment is blocked, and manual configuration in the UI works fine, but we need this automated for environment consistency.

Check your Terraform variable definitions for the genesyscloud_widget resource. The 400 error often occurs when the OAuth client configuration block lacks the specific redirect_uris array, even if the credentials themselves are valid. Genesys Cloud validates the redirect URLs against the registered OAuth client before processing the widget payload.

Error: 400 Bad Request: Invalid OAuth client configuration. Ensure redirect URIs match the registered client.

Add the redirect_uris field to your Terraform resource block. This aligns the widget config with the OAuth client settings.

resource "genesyscloud_widget" "my_widget" {
 name = "Custom Widget"
 oauth_client {
 client_id = var.oauth_client_id
 client_secret = var.oauth_client_secret
 redirect_uris = ["https://your-app.com/callback"]
 }
}

In load testing scenarios, missing this field causes immediate validation failures before any throughput tests can run. Verify the URL matches exactly what is registered in the Genesys Cloud Admin console under Platform > OAuth.
