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.
