Klaviyo Multi-Environment Setup

Overview

Configure Klaviyo across development, staging, and production with separate API keys, environment detection, secret management, and production safeguards. Every environment follows the same shape — detect the env, resolve its config, load its secret, guard destructive/send operations. The lean workflow and first skeleton live here; full step-by-step code lives in references/implementation.md.

Prerequisites

• Separate Klaviyo accounts or API keys per environment
• Secret management solution (GCP Secret Manager, AWS Secrets Manager, Vault)
• klaviyo-api SDK installed

Environment Strategy

Important: Klaviyo does not have a sandbox mode. Use a separate test account for dev/staging to avoid sending real emails.

Instructions

The pattern is the same across all three environments; only the API key and the per-env flags change. Read the matching section in references/implementation.md, then:

1. Write the config module — use Write/Edit to create src/config/klaviyo.ts with a detectEnvironment() helper and a per-env ENV_CONFIGS map that flips enableSending, cache, and rate-limit concurrency by environment.
2. Store secrets per environment — create one secret per env in your platform's secret store (gcloud secrets create, aws secretsmanager create-secret, or Vault). Never commit keys; local dev reads a git-ignored .env.local.
3. Add environment guards — wrap sends and deletions so non-production simply logs instead of touching real data (guardCampaignSend, guardedProfileDeletion).
4. Wire multi-env CI — a GitHub Actions matrix maps staging→staging key and main→prod key, verifies connectivity, then deploys.
5. Validate on startup — connect once, log the resolved account name, and warn loudly if a pk_live_*** key is detected outside production.

Config skeleton (first example)

// src/config/klaviyo.ts — see reference for the full ENV_CONFIGS + getSession
type Environment = 'development' | 'staging' | 'production';

function detectEnvironment(): Environment {
  const env = process.env.NODE_ENV || 'development';
  if (['production', 'staging'].includes(env)) return env as Environment;
  return 'development';
}
// development/staging force enableSending:false; only production sends.

The full config module, per-platform secret commands, guard functions, the CI matrix, and the startup validator are in references/implementation.md.

Output

• src/config/klaviyo.ts resolving a typed config per environment
• Per-environment secrets stored in GCP / AWS / Vault (never committed)
• Send + deletion guards that no-op in dev/staging and act only in production
• A GitHub Actions matrix deploying staging and production with the right key
• Startup validation that logs the connected account and flags a leaked prod key

Error Handling

Examples

Block a campaign send outside production. The guard reads the resolved config and throws when sending is disabled, so a staging run can never email real customers:

guardCampaignSend();   // throws in dev/staging (enableSending:false), passes in prod

Catch a leaked production key in staging. Startup validation warns when a pk_live_*** key is present outside production:

[Klaviyo] Environment: staging
[Klaviyo] Sending enabled: false
[Klaviyo] WARNING: Production API key detected in non-production environment!

The full config module, secret-store commands for each platform, the guard implementations, the CI matrix, and the startup validator are in references/implementation.md.
