Overview

Reseller Dynamic Delivery connects your own SellAuth shop to the shop you resell for (the source shop). You list their product on your shop at your own price. When a customer buys it:
  1. Your shop sends a dynamic delivery request to your personal delivery URL on the source shop.
  2. The source shop verifies the request, charges your reseller balance at your discounted price, and pulls the deliverables from its own stock.
  3. Your customer receives the deliverables (and the source product’s instructions) on your checkout, instantly.
No code is involved. Your margin is the difference between the price you charge your customer and the discounted price charged to your balance.
The fastest way to set this up is connecting your store: it imports the catalog and configures everything below automatically, including the webhook secret. The manual setup on this page is for importing products one by one, or for stores that are not connected.

​
Setup

1

Copy your shop's webhook secret

On your own shop’s dashboard, go to Storefront > Configure > Miscellaneous (dash.sellauth.com/shop#miscellaneous) and copy the webhook secret. If none is shown, click Regenerate.Your shop signs every outgoing dynamic delivery request with this secret. The source shop uses it to verify that requests really come from your shop.
2

Save the secret on the reseller panel

On the source shop’s storefront, open /customer/reseller and click Manage delivery. Paste the webhook secret and enable dynamic delivery.
3

Copy a product's delivery URL

In the reseller catalog (on the panel, or via the List Products endpoint’s dynamic_url field), copy the delivery URL of the variant you want to resell:
Each variant has its own URL. The token in the path is yours personally, so do not share these URLs.
4

Paste it into your own product

On your own shop, create the product you want to sell. Set the variant’s deliverables type to Dynamic and paste the delivery URL into the Dynamic URL field.Set your own price freely; it does not need to match the source shop’s price.
That’s it. Test it with a real (or balance-paid) purchase on your shop.

​
How a delivery is processed

When your customer’s payment completes, your shop calls the delivery URL once per invoice item. On the source shop’s side:
  1. Signature check: the request’s X-Signature header (HMAC-SHA256 of the raw body) is verified against the webhook secret you saved on the reseller panel, or, for a connected store, against that store’s current webhook secret directly. Requests with a missing or wrong signature are rejected, as are requests older than 5 minutes.
  2. Idempotency: your shop sends an Idempotency-Key per item. Retries of the same delivery (after a timeout or a temporary error) can never charge your balance twice.
  3. Order + charge: the source shop creates a reseller order for product_id / variant_id with the quantity your customer bought, charges your balance at your tier price, and pulls stock.
  4. Response: the deliverables and the source product’s instructions are returned to your shop and shown to your customer. Your shop’s own product instructions are used if you set any; otherwise the source shop’s instructions are shown.

​
Failures and refunds

Anything charged for an item that was not delivered is refunded to your reseller balance automatically. Failed items can be retried from your own shop’s invoice page (Redo Dynamic Delivery) once the cause (usually balance or stock) is fixed.
Keep your balance topped up ahead of your sales volume. An order that fails on insufficient balance shows an error to your customer instead of their product.

​
Price ceiling

The source shop can change its prices at any time, and every delivery is charged at the current discounted price. To make sure a price rise can never eat your whole margin, append a max_unit_price parameter to a variant’s delivery URL:
If your discounted unit price (in the product’s currency) ever exceeds the ceiling, the delivery is refused before anything is charged. The failure reason on your invoice item tells you the current price, so you can raise the ceiling (and your own price) or remove the parameter to resume sales.

​
Regenerating credentials

  • Delivery URLs: the reseller panel’s Manage delivery modal can regenerate your delivery token. Every URL you have pasted into your shop stops working immediately, so update them all afterwards.
  • Webhook secret: if you regenerate the secret on your own shop’s dashboard, save the new value on the reseller panel too, otherwise deliveries fail signature verification.

​
Troubleshooting

  • Deliveries fail immediately after setup: the webhook secret saved on the reseller panel does not match your own shop’s current secret, or dynamic delivery is not enabled on the panel.
  • Deliveries stopped working: your delivery URLs were regenerated, your reseller status changed, or the source shop disabled its reseller program. The failure reason is shown on your invoice item.
  • Customer paid but got an error: check the item’s failure reason on your own shop’s invoice. Balance and stock issues are refunded automatically and can be redelivered.
