1. Overview
When you link Postmark to Kurrier, the app sends mail using Postmark’s REST API — no SMTP needed. You just need two keys from your Postmark dashboard:- Server Token — used to send emails from a specific Postmark Server
- Account Token — used for administrative operations
2. Adding Postmark in Kurrier
In Kurrier, go to:Dashboard → Providers → Add Provider → PostmarkEnter the following fields:
| Field | Description | Example |
|---|---|---|
| POSTMARK_SERVER_TOKEN | Your Postmark server API token | 74ef518e-2dfa-451d-b9cf-2843608f789a |
| POSTMARK_ACCOUNT_TOKEN | Your Postmark account-level token | 0762807c-08e9-4ac3-a872-25e635766g61 |
3. Where to Find Your Tokens
- Log in to your Postmark Dashboard.
- Navigate to Servers → (Choose your Server).
- Under API Tokens, copy the Server API Token — this identifies that specific sending server.
- For the Account Token, go to Account → API Tokens and copy your account-level token (used for broader account access).
4. Verify the Connection
After saving, click Verify Connection in the Postmark card. Kurrier will test connectivity by making a simple authentication request to the Postmark API.- ✅ Success: You’ll see a verified badge next to your Postmark provider.
- ⚠️ Failure: Check that both tokens are valid and belong to the same Postmark account.
5. Troubleshooting
| Error | Meaning | Fix |
|---|---|---|
401 Unauthorized | Invalid or expired API token | Re-copy your tokens and re-save |
422 Unprocessable Entity | Domain or sender not verified | Verify your domain or sender in Postmark |
403 Forbidden | Using account token where server token is required | Ensure the Server Token is set correctly |
Timeout | Network/firewall issue | Allow outbound HTTPS to api.postmarkapp.com |
Tip: Kurrier integrates Postmark natively via the official API — no SMTP setup required.
