myPOS integration

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

Use the myPOS integration to award or reverse spend-based stamps.

Data flows from the provider into stmpr.

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

Why use this?

Replace manual data transfers with a verified and observable workflow.

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

Workflow
  1. 1A successful payment or refund
  2. 2Authentication, duplicate protection, and customer matching
  3. 3Award or reverse spend-based stamps

Step by step

  1. Prepare approved myPOS partner or merchant API access.
  2. Create the required API, OAuth, or webhook access in myPOS with the narrowest practical permissions.
  3. In stmpr, open API & Webhooks and create an API key or a webhook. myPOS has no Connect action, so the link runs through Zapier, Make or your own integration, and it needs a plan that includes API access.
  4. In Zapier or Make, build the scenario: the trigger fires at the provider, and the destination action calls the stmpr API.
  5. Configure customer matching in the scenario. Prefer email or phone; use a provider ID only as a stable secondary key.
  6. Run a test with a test customer, then deliver the same event again. Pass a stable event ID, or duplicate protection has nothing to work with.
  7. Test failed delivery, revoked access, a missing customer, cancellation or refund, and consent withdrawal.
  8. After activation, check the first live events in the delivery log. To disconnect, disable the scenario before revoking the API key.
