How to connect a custom-coded site: step by step

Use this when your shop is written in your own code or a platform we do not list. Connecting needs Starter or above. Applying a price to your store needs Premium or above.

Step 1. Make an endpoint on your site

1. 1Create a page or route that accepts a POST request over https, for example https://yourstore.com/hooks/costcal.
2. 2It will receive a small JSON message called price.update with a SKU and a price.
3. 3Verify the signature (the docs have copy-paste code for Node, PHP and Python), then update your own database.
4. 4Reply with status 200 when done.

Step 2. Connect it

1. 1Open the Stores tab and choose Custom site.
2. 2Paste the endpoint address and click Connect store.
3. 3Copy the signing secret that appears. It is shown once. Put it in your server's settings.
4. 4Press Test to send a test message.

Step 3. Give each calculation a SKU

In Saved calculations add the SKU your site uses. When you press Apply price we send that SKU and the new price to your endpoint.

The API documentation page has the full message format and examples.
