NOTES
- Invoicer can automate billing operations using the PayPal Invoicing via Invoices API.
- https://www.paypal.com/merchantapps/appcenter/acceptpayments/invoicing
- The invoices are controlled by a 24-character ID (e.g. "INV2-Z56S-5LLA-Q52L-CPZ5")
- This addon requires the CLIENT-ID and SECRET. (Get on the dashboard)
- Developer Dashboard -> My apps & credentials -> REST API Apps (Live mode)
- https://developer.paypal.com/developer/applications/
- Terminology is based on Invoices API v2 (2019-04).
- Be careful when migrating from implementations prior to April 2019.
- e.g. "merchant" to "invoicer"
- e.g. "billing info" to "recipient"
- When PayPal emails the recipient, the invoice moves from draft to payable state.
- To move from a draft to payable state, the SEND INVOICE action is required.
- Invoice Status: DRAFT, SCHEDULED, SENT, PAID, MARKED_AS_PAID, CANCELLED, REFUNDED,,
- https://developer.paypal.com/docs/api/invoicing/v2/#invoices_create
- However, if "invoice_date" is set, automatically sent at 7:00 of Invoicer time zone
NOTE-ja
- 請求人は、請求書ツール（Invoicing）による請求業務を自動化できます（Invoices API経由）
- https://www.paypal.com/jp/webapps/mpp/merchant/solutions/invoicing
- 請求書は24文字のIDでコントロールされます（e.g. "INV2-Z56S-5LLA-Q52L-CPZ5"）
- このアドオンの利用には CLIENT-ID と SECRET が必要です。（ダッシュボードで取得）
- Developer Dashboard -> My apps & credentials -> REST API Apps (Live mode)
- https://developer.paypal.com/developer/applications/
- 表記は Invoices API v2 〔2019-04〕ベースの用語にて記載されています。
- 2019-04 以前の実装から移行する場合は、特にご注意ください。
- "merchant"（販売人） ではなく "invoicer"（請求人）
- "billing info"（請求先） ではなく "recipient"（受取人）
- "請求書ドラフト" は原則、PayPalから受取人に対しメールされた際に決済可能な状態になります
- すなわち請求書ドラフトを有効化するには、別途「送信」アクションが必要です。
- Invoice Status: DRAFT, SCHEDULED, SENT, PAID, MARKED_AS_PAID, CANCELLED, REFUNDED,,
- https://developer.paypal.com/docs/api/invoicing/v2/#invoices_create
- ただし "請求日" がセットされた場合は、請求人タイムゾーンの 7:00 に自動送信されます
