Integrate WHMCS and Propay
Trexle connects WHMCS to Propay and 100+ other payment gateways using a single plugin for one time annual fee
Propay and WHMCS Integration Guide
To add a ProPay gateway, you need to supply a cert_str and account_num that corresponds to a merchant in your ProPay account.
ProPay supports merchant processing needs by offering both tokenized and non-tokenized approach to accepting credit and debit card payments. ProPay’s ProtectPay tokenization service is recommended for most merchants because it enables processing without the need for sensitive data to touch the merchant’s own network. Using ProtectPay helps merchants maintain compliance with the PCI data security standard, and allows them to focus on growing a business while ProPay helps to protect sensitive data.
For merchants who are comfortable managing their own data security, and who can validate their own PCI compliance, ProPay provides a simpler API-only option to accept credit and debit cards. You will need to generate a new account for each of your merchants before you can transact against ProPay. See section 4.1 of the ProPay API guide for details on creating new accounts. Note that Trexle does not support creating accounts in ProPay via our API. Once you’ve created an account, you can supply your account_num and cert_str as the username and password in your Trexle dashboard Payments Gateways tab.
Then activate as normal..
Take the credentials you just obtained from Propay and navigate to Trexle dashboard, click Payments Gateways and select Propay from the drop down menu as shown below.
Fill into your Propay credential and click Add Gateway. Click the Activate button next to Propay, and it will give you a success message and the button will turn into green. You should see something like below.
