Install Admaxxer on Lemon Squeezy

Paste a Lemon Squeezy API key + register a webhook.

Lemon Squeezy is a merchant-of-record platform like Paddle. Admaxxer reads revenue from order_created webhooks and uses the API key for validation and future order lookups.

Steps

  1. 1 Create an API key

    Lemon Squeezy Dashboard → Settings → API → + Create API key. Copy the key.

  2. 2 Paste into Admaxxer

    Open /integrations, pick Lemon Squeezy, and paste the API key.

  3. 3 Register the webhook

    Lemon Squeezy → Settings → Webhooks → + Add endpoint. URL: https://cdn.admaxxer.com/api/pixel/webhooks/lemonsqueezy/:website_id. Events: order_created. Copy the signing secret into the Admaxxer connect dialog.

  4. 4 Verify

    Run a $0 test order or a 100%-off coupon. Revenue should appear in Admaxxer within 30 seconds.

Troubleshooting

X-Signature header missing.
Make sure the webhook secret is configured in both Lemon Squeezy and the Admaxxer connect dialog. Both must match byte-for-byte.
