Terraform GC Provider: Automating plan/apply in CI/CD

General Discussion
1

Looking for advice on implementing a strict terraform plan gate on PRs and auto-apply on merge using the Genesys Cloud provider. My current GitHub Actions workflow fails with Error: request failed: 401 Unauthorized when the OIDC token expires during the merge trigger, despite using actions/oidc-to-gc-token. How do you handle token refresh or short-lived credential injection in the apply step without hardcoding secrets?

Yep, this is a known issue… The OIDC token lifecycle is strictly managed by GitHub Actions, and the apply step often runs after the token has decayed beyond its validity window. You need to ensure the token refresh happens immediately before the Terraform execution block, not just at the job start.

Configure your workflow to use a separate step for token generation right before the apply command. Use the official action with explicit output mapping to capture the new token, then inject it as an environment variable for the subsequent Terraform step. This avoids hardcoding secrets and ensures the credential is valid for the exact moment of API invocation.

Make sure you bypass the OIDC churn entirely for reliability. In Tokyo, I use static OAuth credentials injected via environment variables. Set GENESYS_CLOUD_CLIENT_ID and GENESYS_CLOUD_CLIENT_SECRET in GitHub Secrets. This avoids token expiry during long CI pipelines. My Datadog metrics show zero auth failures with this method.
