How to Send SliceWP Data to Postmark

Postmark is a transactional email platform for managing subscribers and campaigns. SliceWP runs your affiliate program on WordPress. Postmark is where your affiliate data needs to go. Here is how to connect them without Zapier or code.

Why not just use Zapier?

For connecting your affiliate program to transactional email, a cloud automation service adds cost and a dependency on an external server. AFI runs on your site with no task limits.

What you will need

• A WordPress site with SliceWP installed and configured.
• A Postmark account.
• The Advanced Form Integration plugin (free from WordPress.org).

Connect Postmark to AFI

1. Log in to your Postmark account.
2. Go to Settings → API and copy your Server API Token.
3. In WordPress, go to AFI → Settings → Postmark.
4. Paste the API Token and click Save Changes.

Setting up the integration

1. Create a new integration

Go to AFI → Add New. Name it SliceWP to Postmark.

2. Pick your trigger

Select SliceWP as the form provider. AFI fires when an affiliate registers or a commission is recorded, giving you access to affiliate details, referral amounts, and commission data.

3. Select Postmark as the destination

Choose Postmark from the platform dropdown and pick Add Mailing List Member. This adds a member to a Postmark mailing list.

4. Map fields

Match each Postmark field on the left to the corresponding SliceWP field on the right. Common mappings include affiliate name, email, referral ID, commission amount, and status. You can also use smart tags like {{_submission_date}}.

5. Add conditions if needed

Only want to send certain referrals? Set up a conditional rule based on any field value.

6. Save and test

Click Save Integration. Trigger a test event in SliceWP. Check Postmark to confirm the data arrived. If anything looks wrong, open AFI → Log to see the exact request and response.

Free vs Pro

The free version maps email and name to Postmark with unlimited referrals. Pro adds custom field mapping. No per-referral fees on any plan.

Frequently asked questions

Which SliceWP events trigger the integration?

No. AFI sends data to the destination after the affiliate event completes. Your site performance is not affected.

Can I send affiliate data to multiple platforms?

Yes. Create a separate integration for each destination, and every event flows to all of them simultaneously.
