Tax lines won't automatically generate in Shopify API order - rest

Question

I am posting the following to the Shopify API order endpoint:
{
"order": {
"email": "some#email.com",
"financial_status": "paid",
"fulfillment_status": null,
"send_receipt": true,
"send_fulfillment_receipt": true,
"note": "Created by somename",
"line_items": [
{
"variant_id": 21718275463,
"quantity": 1,
"price": 99,
"requires_shipping": true,
"product_id": 6820646151
},
{
"variant_id": 21717700871,
"quantity": 1,
"price": 1000,
"requires_shipping": true,
"product_id": 6820646151
},
{
"variant_id": 21717690055,
"quantity": 1,
"price": 555,
"requires_shipping": true,
"product_id": 6821668807
}
],
"processing_method": "offsite",
"shipping_address": {
"first_name": "Chris",
"address1": "10101 Musick Road",
"phone": "9999999999",
"city": "St. Louis",
"zip": "63123",
"province": "MO",
"country": "United States",
"last_name": "Becker",
"name": "Chris Becker",
"country_code": "US",
"province_code": "MO"
},
"source_name": "somename",
"taxes_included": false,
"shipping_lines": [
{
"title": "standard",
"price": 0.00,
"code": null,
"source": "brand owner on shopify",
"carrier_identifier": null,
"tax_lines": null
}
],
"tags": "some Order"
}
}
and receiving a response without tax lines that are filled. I have seen on the shopify forum that the taxlines are supposed to then be automatically
calculated and filled by shopify. I tried doing it with a customer as well but that didn't work either.

Answer 1

The Orders API will not auto-calculate the taxes but if your app knows how much they are then you can include this data using tax_lines and total_tax:
{
"order": {
"line_items": [{
"title": "Big Brown Bear Boots",
"price": 74.99,
"quantity": 3,
"tax_lines": [{
"price": 13.50,
"rate": 0.06,
"title": "State tax"
}]
}],
"total_tax": 13.50
}
}
