MailerLite integration
Prerequisites, setup, field mapping, testing, and troubleshooting for the MailerLite connection.
Use the MailerLite integration to upsert the subscriber, group, and loyalty fields.
stmpr sends the selected data to the provider.

Why use this?
Replace manual data transfers with a verified and observable workflow.
Idempotency prevents duplicate rewards, while consent gates protect marketing data transfers.

Step by step
- Prepare a MailerLite API token and access to the target group.
- Create the required API, OAuth, or webhook access in MailerLite with the narrowest practical permissions.
- In stmpr, open Developers → Integrations and choose Connect. The account is verified here, but nothing is synchronised to MailerLite yet.
- 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.
