How do I correctly to handle the authentication handshake when a Genesys Cloud Data Action needs to refresh an OAuth token for an external workforce management system during peak schedule publishing hours? We are currently experiencing intermittent 504 Gateway Timeout errors specifically when the Data Action attempts to exchange a refresh token for a new access token via the external API endpoint.
The environment is set up with a standard Genesys Cloud organization in the America/Chicago timezone. The Data Action is triggered by a scheduled flow that runs every Sunday at 02:00 AM CST to push the finalized shift schedules to our third-party WFM provider. The issue arises when the OAuth token expires exactly during this window. The HTTP request task in Architect is configured with a 15-second timeout, which seemed sufficient initially. However, the external provider’s token endpoint occasionally takes longer than 10 seconds to respond under high load, causing the Genesys Cloud side to abort the connection before the 200 OK response is received.
The error payload returned by the Data Action execution is as follows:
{
"code": "platform.integration.http.timeout",
"message": "HTTP request timed out after 15000ms",
"statusCode": 504,
"details": "Connection reset by peer during OAuth token exchange"
}
Increasing the timeout to 30 seconds is not a viable option because it blocks the downstream tasks in the flow, which include notifying agents of their shifts via email and SMS. This delay causes a cascade of failures in the notification system, leading to a significant drop in schedule adherence and agent satisfaction scores. We have verified that the external API is functioning correctly and returns the token within 12 seconds on average.
Is there a recommended pattern for handling asynchronous token refreshes within Genesys Cloud Data Actions? Perhaps using a webhook to trigger the refresh separately before the main schedule publish flow executes? We need a solution that ensures the schedule is published reliably without blocking the agent notification chain, while maintaining the integrity of the OAuth session across multiple organizational units.
