async function execute(input: Parameters<GitHubIntegration["actions"]["actionsCreateOrUpdateEnvironmentSecret"]>[0]) {
  const app = new App({ apiKey: process.env.ALTER_API_KEY! });
  try {
    const provider = new GitHubIntegration(app, { grantId: process.env.PROVIDER_GRANT_ID! });
    const call = await provider.actions.actionsCreateOrUpdateEnvironmentSecret(input);
    const result = await call.wait();
    return result.bodyJson();
  } finally {
    await app.close();

Policy, approvals and errors

SDK function policy ID: github.actions_create_or_update_environment_secret. Catalog operation: actions/create-or-update-environment-secret. Rules can name either ID; function rules distinguish managed calls and conservatively cover raw calls sharing the route. Existing grant permissions and policy rules apply. wait() returns an immediate result or waits for a required approval; it never approves the request itself. Persist the approval ID to resume after a restart.

Provider errors retain their response; JSON decoding raises ProviderAPIError for provider failures. ManagedOperationError identifies contract/input/retention errors. See error handling and provider-specific behavior. Sensitive input may be refused before approval storage. A decoding error never resubmits a write.
