Knowledge base / Integrations

Postmark integration

Prerequisites, setup, field mapping, testing, and troubleshooting for the Postmark connection.

Use the Postmark integration to send the selected Postmark template.

stmpr sends the selected data to the provider.

Connecting the account does not activate a workflow by itself. Select the loyalty card, trigger, destination action, and customer matching rule separately.

Postmark

Image placeholder: Postmark: create the required access

Why use this?

Replace manual data transfers with a verified and observable workflow.

Idempotency prevents duplicate rewards, while consent gates protect marketing data transfers.

Example

A reward or consented transactional event → match the customer → send the selected Postmark template.

Workflow

1A reward or consented transactional event
2Authentication, duplicate protection, and customer matching
3Send the selected Postmark template

Step by step

Prepare a Postmark server token and verified message stream.
Create the required API, OAuth, or webhook access in Postmark with the narrowest practical permissions.
In stmpr, open Developers → Integrations and choose Connect.
Select the loyalty card, trigger event, and destination action.
Configure customer matching. Prefer email or phone; use a provider ID only as a stable secondary key.
Run a test with a test customer, then deliver the same event again to verify duplicate protection.
Test failed delivery, revoked access, a missing customer, cancellation or refund, and consent withdrawal.
After activation, monitor the first live events. To disconnect safely, disable the workflow before revoking provider access.

What you select and verify

Trigger: a reward or consented transactional event
Action: send the selected Postmark template
Loyalty card, business, or location
Customer matching and required fields
Consent, refund, cancellation, and no-show rules
Test data, duplicate protection, and delivery log

Tip

Start with one test card and customer, then expand the workflow only after its result is verified.

Note

Do not grant account-wide access when a restricted key or scope is enough. stmpr cannot use data that the provider API does not expose.
