Invoice (Japanese Tax)

A standard Japanese invoice sample covering multiple line items, consumption tax and rounding. Clone the template into your own workspace, pass the published input JSON to POST /v1/file/sync/single as content.params, and you reproduce the same output as the finished PDF on GitHub.

  • What it exercises: Multiple line items (line-item array) / consumption tax / rounding / Japanese text
  • Expected pages: 1
  • Supported API version: v1 (POST /v1/file/sync/single)
  • GitHub: examples/invoice

When should I use this invoice sample?​

Use it when you want to confirm that the API can produce an invoice with several line items where consumption tax and rounding are involved. It exercises amount calculation and Japanese text together, which makes it a good first sample to try.

1. Clone the template​

Clone "請求書" from the template gallery into your own Re:port Flow workspace. After cloning, look up your own design ID.

2. Finished PDF (expected output)​

The verified finished PDF is available on GitHub.

3. Input JSON​

This is the input data you pass to the API as content.params (view on GitHub).

4. Call the API​

Run the request with your appkey and the design ID and version of your clone.

curl -X POST https://api.re-port-flow.com/v1/file/sync/single \
  -H "appkey: ak_xxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "designId": "(your cloned design ID)",
    "version": 1,
    "content": { "fileName": "invoice", "params": { /* the input.json above */ } }
  }' \
  --output output.pdf

curl / Node.js / Python request examples are on GitHub.

note

The keys in params must match the parameter definition of the template you cloned. You can fetch that definition with Design Parameters (GET /v1/file/design/parameter/{designId}?version=1).
