內容簡介
總結：ifthenpay 外掛不提供內建的循環計費功能，而是透過建立簡單易懂的支付週期來實現循環會員制。支付週期是依序計算，以確保客戶不會因此失去已支付的時間。此外，使用者可以進行一次性支付以及循環會員購買，並可以透過管理後台進行基本銷售和退款操作。
問題與答案:
1. ifthenpay 外掛的核心功能是什麼？
- 答：提供循環會員制（按期循環計費）、一次性支付、自行控制部分退款、基本銷售和退款報表、自動支付確認（不儲存信用卡號碼）等功能。
2. 循環計費是如何運作的？
- 答：使用者購買會員資格時會設定一個週期（例如：每個月）。外掛會建立第一個支付週期以及該週期的支付參考。當支付完成後，週期會被標記為已支付，並準備下一個週期。週期會依序計算，以避免重疊並保留客戶已支付的時間。
3. 使用 ifthenpay 外掛需要滿足什麼條件？
- 答：需要擁有活躍的 ifthenpay 商家帳戶以及 MemberPress 的 Gateway Key。可以從 ifthenpay 的支持團隊那裡尋求協助取得 Gateway Key。
原文外掛簡介
ifthenpay does not offer built-in recurring billing. This plugin makes recurring memberships work by creating simple, easy-to-understand payment periods. When a period is paid, the membership continues; if not paid, MemberPress marks that period as “Lapsed” and the system waits for the end-customer to “Update” their subscription by making a manual payment for the next computed period. Periods are computed sequentially so customers never lose paid time — the next period is only created after the previous one is completed. An admin may also change the subscription status if needed.
In plain terms you get:
* One-time payments and recurring memberships (period engine)
* Partial refunds you control
* Merchant backoffice (basic sales & refunds) on web + mobile
* Secure automatic payment confirmations (no card numbers stored)
All settings are made in MemberPress and in your ifthenpay Backoffice. The plugin is built so store owners can manage payments without needing deep technical knowledge.
Key Features
Period-based recurring (sequential, preserves paid time)
One-time payments (standard purchase flow)
Automatic payment confirmation (fast access)
Lapsed period handling with manual Update action
Admin partial refunds (future/unconsumed periods)
Multiple local payment types (cards, wallets, transfers)
Merchant backoffice (basic sales & refund reports)
Security first (signed callbacks, no card data stored)
How Period-Based Recurrence Works
User purchases a membership with a cycle (e.g. monthly).
The plugin creates the first payment period and a payment reference for that period.
When payment is received, the period is marked paid and the next period is prepared. Periods are computed sequentially to avoid overlap and preserve any paid time for the customer.
Admins can generate or edit periods from the transactions screen.
Requirements
An active ifthenpay merchant account.
A Gateway Key for MemberPress (request this from ifthenpay support/helpdesk).
The payment methods you want enabled on that Gateway Key (your ifthenpay backoffice lets you choose).
WordPress 5.0+, PHP 7.4+, and MemberPress installed.
HTTPS (SSL) enabled on your site.
Refund Policy Management
Scope: refunds apply only to future or unconsumed paid periods (no retroactive time reimbursement).
Process:
* Admin inputs desired refund amount per transaction/period.
* Optional min/max limits can guide consistency.
* Approval required before issuing ifthenpay refund or internal credit note.
External Services
