In other words, the IF customer does NOT have a billing agreement, after an unsuccessful attempt to load WHMCS, the customer automatically receives an email informing him that he has to log in and make the payment manually!? We`ve left coding and API software with all our hands so you can offer your customers a flawless billing and cash flow experience – and enjoy a simpler back-end billing process! Cause This is caused by the fact that whmcs has not read the hooks quickbooks_sync or PayPal-billing-center .php file. This is usually caused by a module level where an error occurred or after a migration from another WHMCS installation. Solution You have to load our hooks file once in WHMCS so that it can carry out… Yes, migration 7.7->7.8 with the myworks Billing Agreements module is painful. An error was posted immediately after installation. It turns out that we had installed github.com/WHMCS/sample-gateway-module and that whcms does not allow any duplicate function name. Developers need to take care of it. Recovering reference transactions is not as simple as the developer exposes them. I wrote to PayPal two weeks ago and I still haven`t responded. Judging by other comments, this feature is only enabled for monthly transaction accounts over 30K.
Don`t buy this module until you`ve activated reference transactions in your PayPal account. We are in need if a custom payment module to establish recurring payment agreements with PayPal billing agreements with reference transactions. This module is different from the standard feature built into WHMCS, which creates a recurring payment profile for a debtor. We would like to use the PayPal of the reference transaction search and on-demand payment functions to be able to change the amount of the payment and charge if necessary, instead of waiting for PayPal to send a fixed payment in the PayPal`s recurring payment schedule. We have set up our PP account to make these services possible. – Is a « sample » or 0.00 invoice allowed just to charge the normal price to the customer after x days? One of the features we introduced in V2.6 is an option to display a green warning at the top of the billing page in the WHMCS customer area, if a settlement agreement PayPal or a credit card is registered to the customer`s account – and automatic processing is… In addition, this module must co-exist with the current standard PayPal payment system in WHMCS and continue to support current payment agreements (legacy) with established customers. As a result, the IPN processor PayPal WHMCS must work so that IPN notifications for existing payments (legacy) are transmitted to the currently integrated WHMCS module, while IPN notifications related to the new module are properly transmitted and processed by the new module. Again, the most important problem is not that automatic payments PayPal are not processed, but that the « Customer Summary » page causes a 500 error for multiple customers (for whom a billing agreement is in place). Fix the feature, OK, I understand, it may take a few weeks to fix this (although they had plenty of time to do so because WHMCS provided betas), but also a critical problem, not being able to see the summary of your customers should have been corrected as soon as possible.
