[joshgubler]

Setting the RFC env vars (there are several blocks; here's one):

hw-fargate-api/.github/workflows/deploy.yml

Lines 27 to 29 in 5a70a7c

	"rfc_key_name":"standard_change_sandbox_client_key",
	"rfc_secret_name":"standard_change_sandbox_client_secret",
	"rfc_template_id":"Codepipeline-Standard-Change"

and the Standard Change steps:

hw-fargate-api/.github/workflows/deploy.yml

Lines 261 to 267 in 5a70a7c

	- name: Start Standard Change
	uses: byu-oit/github-action-start-standard-change@v1
	id: start-standard-change
	with:
	client-key: ${{ secrets[matrix.env.rfc_key_name] }}
	client-secret: ${{ secrets[matrix.env.rfc_secret_name] }}
	template-id: ${{ matrix.env.rfc_template_id }}

and

hw-fargate-api/.github/workflows/deploy.yml

Lines 290 to 298 in 5a70a7c

	- name: End Standard Change
	uses: byu-oit/github-action-end-standard-change@v1
	if: always() && steps.start-standard-change.outcome == 'success' # Run if RFC started, even if the deploy failed
	with:
	client-key: ${{ secrets[matrix.env.rfc_key_name] }}
	client-secret: ${{ secrets[matrix.env.rfc_secret_name] }}
	change-sys-id: ${{ steps.start-standard-change.outputs.change-sys-id }}
	work-start: ${{ steps.start-standard-change.outputs.work-start }}
	success: ${{ job.status == 'success' }}
