Can you share some req_xxx IDs for the API requests?

[boreal sable]

req_N6ITjzGuSPgVI2

req_kJDAus7KO4GV8l

req_8scIL4gsTFkoSg - invoice item req

SO you want the /v1/invoiceitems request to put onto the invoice you just created here: https://dashboard.stripe.com/logs/req_N6ITjzGuSPgVI2 ?

[boreal sable]

that's correct yes

so the invoice pulls data from the invoice item

price being the main value

[shy gale]

You should pass the invoice parameter when creating the Invoice Item: https://stripe.com/docs/api/invoiceitems/create#create_invoiceitem-invoice

See: https://stripe.com/docs/invoicing/integration#create-invoice-code

In your request, you're just adding the new Invoice Item to the customer

It'd be picked up on the next invoice you create

[boreal sable]

so the invoice must be created before the invoice item?

[shy gale]

Not necessarily no. If you want to create Invoice Items first, and then the Invoice you'll need to pass this parameter: https://stripe.com/docs/api/invoices/create#create_invoice-pending_invoice_items_behavior

pending_invoice_items_behavior: 'include'. This behaviour changed in the recent API version release: https://stripe.com/docs/upgrades#api-versions:~:text=The pending_invoice_items_behavior parameter,now exclude.
