Shopify Post-Purchase Checkout Extension - How to get the order Id?

Retired Boards Appdev Metafields

I have created a basic Shopify post-purchase checkout extension, using this tutorial : https://shopify.dev/apps/checkout/post-purchase/update-an-order-for-a-checkout-post-purchase-app-extension

The buyer sees the post purchase page after they have placed an order and can add a product to their existing order. I want to know the order Id of the edited order, so I can tag it with my app’s name.

I have not been able to find a way to get the order Id of the initial purchase. Need some help with this please!

Any updates to this?

I’m facing similar issues and I’m thinking of matching referenceIds between the shouldRender Input data and the order webhooks to get the order id but this feels more complicated than it should be, and I’m not even sure if it’ll work.

Hey,

You are on the right path, but you won’t be able to match reference Ids, as they don’t appear in the order webhook payload.

Instead you will need to set a metafield when calling signchangeset. The “changes” variable that looks like :

[{type: 'add_variant', variantId: variantID, quantity: 1}]

will become :

[{type: 'add_variant', variantId: variantID, quantity: 1},{type: "set_metafield", namespace: "{your app name}", key: "isUpsellOrder", value: 1, valueType: "integer"}]

Once this is done, then on the server side you will need to subscribe to the order webhook and check for the “isUpsellOrder” metafield by calling the Order API’s metafields endpoint:

$metafieldData = $shopifyClient->call('GET', '/admin/api/2021-07/orders/'.$orderId.'/metafields.json');

Parse through the metafield data and see if isUpsellOrder is true. This way you can connect your upsell order to the order Id.

Thank you! I was confused about metafields too and this clears it up.

I should also mention I did some testing last night and it looks like the “referenceId” can be matched to the order webhook’s “checkout_token”. I’m not sure how consistent this is but I’ll be doing more testing today.

I think you are right! Looking forward to know what you find out after testing.

This would make things much more simpler!

It’s looking pretty good, everything’s working as expected for me when using referenceId as the checkoutToken.

Thanks I did the same for now.

Did this end up being the final solution you landed on? Having trouble with this at the moment. Also curious how you were accessing the webhooks in the first place?
