Creem integration: merchant-of-record payments for SaaS

Creem is a merchant of record: it sells to your customers on your behalf and takes care of sales tax and VAT around the world. That makes it a popular choice for indie makers who don't want to register for tax in every country. ShipAny supports Creem for both one-time payments and subscriptions, using the same order → subscription → credits pipeline as Stripe.

What ShipAny handles

• Checkout for one-time and subscription plans, created from your server-side pricing catalog.
• Signed webhooks at /api/payment/notify/creem that mark orders paid, create or renew subscriptions and grant credits — atomically and idempotently.
• Sandbox and production environments, switchable in the admin panel.
• A test amount setting, so you can run a real end-to-end payment for $0.01 before going live.

Setup

1. Sign in to the Creem dashboard. Use Test mode (top right) while you build.
2. Under Developers, copy your API key.
3. Under Products, create one product per plan in your pricing catalog. Currency, price and billing interval must match the plan exactly. Copy each product ID.
4. Add a webhook pointing to https://<your-domain>/api/payment/notify/creem and copy its signing secret.
5. In ShipAny, open Admin → Settings → Payment → Creem: switch on Enable Creem, choose the environment, fill in the API key and signing secret, and paste a JSON object mapping your plan IDs to Creem product IDs:

{ "starter_monthly": "prod_xxx", "pro_yearly": "prod_yyy" }

6. Set Creem as the default provider (or turn on the payment-method selector) under Payment → Basic, then run a test purchase.

Tips

• Keep the product mapping in sync. If you add a plan or change a price, create the matching Creem product and update the mapping — Creem charges the price of its own product.
• Switch the environment and keys together when you go live: sandbox keys don't work against production and vice versa.
• Creem works well alongside Stripe: offer Stripe for cards and Creem for buyers who need a merchant-of-record invoice.
