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 WFM scheduling templates API 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?
