Stuck on a rate limiting issue while trying to sync shift templates from our AppFoundry integration to multiple Genesys Cloud organizations. We are using the POST /api/v2/wfm/scheduling/scheduletemplates endpoint to push bulk updates for our partner clients. The OAuth tokens have the correct wfm:schedule:write scope, and the payload structure matches the documentation exactly. However, when we process more than 50 templates in a single batch, we start receiving 429 Too Many Requests errors with a retry-after header that seems inconsistent. We have implemented exponential backoff, but the errors persist even when spacing requests by 2 seconds. The SDK version is genesys-cloud-node-sdk v6.2.1. We need a reliable way to handle high-volume WFM data synchronization without hitting these limits. What is the recommended approach for bulk WFM API operations to avoid rate limiting while maintaining data consistency across multiple organizations?
