Due to a migration between BTCPay servers (with 1rst server lost, incl data), plugin can't fech the old invoices data.
Leading to a fatal error

An exception has been thrown during the rendering of a template ("Error during GET to https://btcpay.website.com/api/v1/stores/DHKa8TTypXFb9Xau9YU19aBiiFwFPYMMQXno6Lx13y6W/invoices/LAhsGNNLu7gFqFDvhp6S4E/payment-methods. Got response (404): {"code":"invoice-not-found","message":"The invoice was not found"}").
[Twig\Error\RuntimeError 0]

Describe the solution you'd like
Error handling, showing invoice as not found instead of raising uncaught 404 API call.

Describe the bug
When I installed the BTCpay module, out of the box, I was having issue, where the code apparently tried to submit array into bool argument when creating the Configuration object.

To Reproduce
Steps to reproduce the behavior:

1. Have a new PrestaShop 8.1.3
2. Add BTCPay module
3. Click configure
4. See Error

Expected behavior
Configuration tab shows normally.

Screenshots

Your BTCPay Environment (please complete the following information):

• BTCPay Server Version 1.12.4 (irrelevant for this issue)
• Deployment Method: Presta - Docker, BTCPay - Start9
• Browser Firefox

Logs (if applicable)

Setup Parameters
Default

Additional context
It can be fixed by replacing a line in constants:
public const CONFIGURATION_SHARE_METADATA = 'BTCPAY_SHARE_METADATA';
with:
public const CONFIGURATION_SHARE_METADATA = false;

Describe the bug
Module does not invoke legacy controller admin_btcpay_cofigure because (I think) redirectAdmin calling symphony controllers does not work in prestashop 1.7.4. When you open configuration of the module, you get page not found.

The problem is in my opinion in controllers/admin/AdminConfigureBTCPayController.php (legacy controller), in:

Steps to reproduce the behavior:Tools::redirectAdmin($this->context->link->getAdminLink('BTCPay', true, array(
'route' => 'admin_btcpay_configure'
)));

I think there are two possible problems in this code:

• I think modules do not route to symphony controllers in this version, because in prestashop guide developers say symphony controllers is implemented in modules from prestashop version 1.7.5.
• Tools::redirectAdmin has different parameters in every version of prestashop, and I think the invocation in the module is from 1.7.5 or 1.7.7.

I do not know if there is another way to invoque redirectAdmin compatible with 1.7.4 and the module. I have been months trying to fix this module for my installation, because I can not upgrade PHP and prestashop in this machine (we have a lot of modifications and overloads and for upgrading our system we would have to rewrite a lot of code).

To Reproduce

1. Upload module on prestashop 1.7.4 control panel.
2. Click on 'Configure module'
3. See 'page not found' error.

Expected behavior
The module configuration form to be loaded.

Your BTCPay Environment (please complete the following information):

• BTCPay Server Version 1.3.6.0.
• Deployment Method: Manual
• Browser firefox, brave, chrome, falkon, ...

Additional context
I had to adapt module for php 7.0 for my installation, erasing php function return types in declarations, but this do not afect this issue, because code loads and problem is whith prestashop routes.

Thanks in advance.

Edu.

We need to make sure that our module will work with the newly release Prestashop 8. Changes can be found here: https://devdocs.prestashop-project.org/8/modules/core-updates/8.0/

BTCPay PrestaShop plugin is a bridge between your server (payment processor) and your e-commerce store. No matter if you're using a self-hosted or third-party solution from step 2, the pairing process is identical.

1. In the BTCPay server url-field, enter the full URL of your host (including the https) – https://btcpay.mydomain.com
2. Select the default transaction speed (this will change how much BTCPay recommends as transaction fee)
3. Select the relevant order mode for your store (order is created before or after payment)
4. Go to your BTCPay server, select a store, open its settings and select "Access Tokens".
5. Click on "Create a new token", select your store and then approve. 5.1. You will see: "Server initiated pairing code: XXXX".
6. Enter your pairing code.
7. Press save. Prestashop will now attempt to make a connection with your BTCPayServer.
8. A message will be shown if the connection was successful.
9. It's recommended to do a test purchase.

Point 4 to 6 I don't know how to do. In the module version 1.0.1 (5.0) not to be the same use.
Can I do the point 4 and 5 but the 6 I don't know where I have to put the pairing code?

I do the installation but when my PrestaShop try to connect doesn't work revert a 504 error.

Hi i have a problem with Plugin Prestashop:
```
This value should not be empty.
This value should not be empty.
This plugin expects all passed permissions to be given. Remove the new API key and try again.

Plugin [Release v5.1.5](https://github.com/btcpayserver/prestashop-plugin/releases/tag/v5.1.5)
Prestashop Version 1.7.8.6

Is your feature request related to a problem? Please describe.
Trying to use the module with prestashop v1.7.8.3, it doesn't create the order anymore.
Got "There is no order that we can process" error after payment validation.

Describe the solution you'd like
Fix module order creation

Is your feature request related to a problem? Please describe.
Under certain circumstances it could happen that a merchant manually changed the order status to processing or completed and in this case they might want no automatic change of order status anymore.

Describe the solution you'd like
Add an option (or consider making it by default) that the statuses of processing or complete are protected and webhook events are unable to change the order status. We should still add some note to the order notes in this case.

Is your feature request related to a problem? Please describe.
Currently the module does not support Prestashop's multistore feature. This means that once you've connected the module to a BTCPay Server, that server (and selected store) will always be used.

Describe the solution you'd like
Configuration related to the module should be stored in a multistore compatible way.

A nice detailed write-up about how to develop multistore modules can be found here: How to develop MultiStore compatible module in Prestashop.

Describe the bug
With order after payment option, I have a lot of critical errors.
Seems like a lot of orders failed to load after payment failure.

To Reproduce
Steps to reproduce the behavior:

1. Setup "Order after payment"
2. Fail to pay the invoice on time
3. Get redirected to redirect url
4. See error

Expected behavior
Get redirected to main webpage / catch the error instead raising major failure.

Hello guys!

Prestashop 1.7.8.7
BTCPay Server - Prestashop module (v5.2.0)
PHP 7.4
BTCPayServer 1.7.1

Installation went smoothly. API set, shop and user configured. The problem is that I cannot enable BTCPayServer for any currency.
On the image below you can see that I can select Bank Transfer for any of the shop currency but in the same time you can see there is no selector for BTCPayServer. Tried to install/uninstall it. All other payment modules appears to be OK.

Is your feature request related to a problem? Please describe.
Cryptocurrency payment gateway have a high rate of failure. A lot of people just give out, leaving unpaid order on prestashop dashboard.
On medium shop, it's 10/15 orders cancelled per day due to crypto payment failure.

Describe the solution you'd like
Create order after invoice paid webhook (need fallback mechanism)
or implement kind of order deletion / hiding process when payment failed.

We already sanity check the PHP version and BTCPay Server version, but it might be smart to extend these checks even further.

Possible checks:

• Ensure that no relevant core classes are overwritten
• Ensure all expected PHP extensions are available to us
• Ensure that we have internet access
• Ensure a proper domain is configured
• Ensure HTTPS is configured (and potentially enforced)
  • HTTPS is required for the frontend controllers, so this is technically a must.

This could help decrease the amount of issue people have by showing them upfront what is wrong with their PrestaShop installation.
