Description
Interac (Manual) Payment Integration for WHMCS
Interac (Manual) Payment Integration for WHMCS gives Canadian customers clear instructions for paying invoices through Interac e-Transfer. Instead of processing a card or connecting to an external payment API, the module displays the information customers need to send their payment manually from their bank account.
The dedicated checkout instructions include your configured recipient email address, the payment amount, order number, invoice reference, and optional security question and answer. This creates a more organized offline payment process and helps customers include the correct information with their transfer.
Dedicated Interac Instructions Page
When a customer selects Interac and clicks Pay Now, the module opens a dedicated WHMCS client-area page containing the relevant e-Transfer instructions. Access is limited to logged-in clients, keeping the payment information within the customer account experience.
Core Features
- Manual Interac e-Transfers: Offer Interac as an offline payment option for Canadian customers.
- Configurable Recipient Email: Display the email address customers should use when sending their transfer.
- Optional Security Question: Add a custom e-Transfer security question when required.
- Optional Security Answer: Show the corresponding answer on the payment instructions page.
- Invoice Reference: Tell customers which invoice number to include in their transfer message.
- Order Number Display: Show the associated WHMCS order number for easier reference.
- Payment Amount Display: Present the invoice amount together with the configured currency formatting.
- Client Login Protection: Only authenticated WHMCS clients can access the instruction page.

Manual Payment Verification
This module provides payment instructions but does not connect to an Interac API or automatically confirm transfers. After receiving the e-Transfer, an administrator must verify the payment and record it against the appropriate WHMCS invoice.
Flexible Admin Configuration
Administrators can set the recipient email address from the WHMCS payment gateway settings. The security question and answer fields are optional and can be left empty when they are not needed.
