This plugin integrates the ifthenpay payment gateway with LatePoint to enable seamless payment processing for appointment bookings. It supports multiple payment methods, including local options like Multibanco, MB WAY and Payshop, as well as international ones like PIX. Instant methods (MB WAY, cards, PIX, …) are handled via secure pay-by-link, with no sensitive card data stored on your site; Multibanco and Payshop are deferred — the customer gets a reference to pay at an ATM, via homebanking, or at a Payshop agent, and the booking confirms automatically once it’s paid. When a customer books an appointment, they can select their preferred payment method, and a secure payment page (or reference) is shown for completion.
In plain terms you get:
* One-time payments for bookings, instant or deferred (Multibanco, Payshop)
* Support for invoices and orders
* Merchant backoffice (basic sales) on web + mobile
* Secure automatic payment confirmations (no card numbers stored)
* An admin Tools page to recover a stuck payment without needing server access
All settings are made in LatePoint. The plugin is built so store owners can manage payments without needing deep technical knowledge.
Key Features
- Easy integration with LatePoint booking flow
- Invoice payments (Orders & Invoices support)
- Secure pay-by-link transactions
- Deferred payment references (Multibanco, Payshop) with automatic slot release on expiry
- Automatic payment confirmation (fast access)
- Multiple local payment types (cards, wallets, transfers, vouchers)
- Merchant backoffice (basic sales & refund reports)
- An admin Tools page: re-register the payment notification URL, recheck or cancel a stuck deferred payment, and review realtime payments that settled without a completed booking — all from wp-admin
- Security first (signed callbacks, no card data stored)
Requirements
- An active ifthenpay merchant account — subscribe here to obtain your credentials.
- A Static Gateway Key provisioned for the LatePoint context (request this from ifthenpay support/helpdesk).
- The payment methods you want enabled on that Gateway Key (our helpdesk team will guide you).
- WordPress 6.5+ and PHP 7.4+, and LatePoint 5.6+ installed and activated.
- HTTPS (SSL) enabled on your site.
- Outgoing email delivered reliably — many hosts block or throttle PHP’s default mail() function. An SMTP plugin (e.g. WP Mail SMTP) is recommended so the New Booking and Payment Received notifications actually reach customers and agents.
External Services
This plugin integrates with the ifthenpay payment platform to process payments for LatePoint bookings. ifthenpay is a third-party service that provides secure payment processing for various methods including cards, wallets, and local bank transfers.
- LatePoint (appointment-booking plugin): we extend its framework classes (
OsFormHelper,OsSettingsHelper, etc.). - ifthenpay Backoffice & Integrations
- What it is and what it is used for: The ifthenpay Backoffice is the merchant dashboard for managing payment integrations. The plugin uses the ifthenpay API to retrieve account configuration, generate payment links, and process payments.
- What data is sent and when:
- During setup: Backoffice Key and Gateway Key (stored securely in site settings) to authenticate and retrieve available payment methods.
- During payment processing: Minimal transaction details including transaction ID, amount, and booking details to generate payment references.
- End-User License Agreement (EULA): EULA
- Privacy Policy: Privacy Policy
- Network & VPN Requirements: Outbound HTTPS requests are made to ifthenpay APIs for setup, link generation, and status validation. Servers behind strict firewalls or restrictive outbound VPNs must allowlist the following domains to prevent connection timeouts:
- api.ifthenpay.com (https://api.ifthenpay.com)
- ifthenpay.com (https://ifthenpay.com)
- Inbound callback URL: ifthenpay itself calls back to
https://your-site.com/wp-json/ifthenpay-lp/v1/callbackto confirm a payment. A site behind its own WAF, security plugin, or reverse proxy must allow GET requests to that path from ifthenpay’s servers, or payment confirmations will not arrive.
All network requests are performed server-side over HTTPS. Sensitive credentials are stored in site options and are not publicly exposed. The plugin does not store raw card numbers or full bank account details.
