# Paraşüt Connection Update for WISECP 3.x

https://docs.wisecp.com/en/parasut-connection-update-for-wisecp-3

This package moves the Paraşüt addon on WISECP 3.1.9.8.x to Paraşüt's new sign-in method, so invoices keep flowing after December 10, 2026.

## Who It Is For

The package is for installations that run the Paraşüt addon on WISECP **3.1.9.8.1** or **3.1.9.8.2**. Update an older 3.x version to 3.1.9.8.2 first. Do not install this package on WISECP 5. The same fix arrives with the WISECP 5 update.

The addon settings screen is on the **Tools** > **Addons** page of the admin panel. Click the **Settings** button on the Paraşüt row. The addon screen itself is in Turkish, so this article quotes its labels as they appear.

## What Changes

Paraşüt closes the e-mail and password sign-in on December 10, 2026. The package adds the **Paraşüt Bağlantısı** (Paraşüt Connection) row and the **Paraşüt ile Bağlan** (Connect with Paraşüt) button to the settings screen. The e-mail and password fields leave the screen; their saved values stay.

Installing the package changes nothing on its own. The addon keeps working with your saved e-mail and password until Paraşüt closes the old method.

### Connection states

The **Paraşüt Bağlantısı** row shows one of these states.

- **Eski yöntemle bağlı**: Connected the old way. Invoices go out with the e-mail and password. Switch to the new method before December 10, 2026.
- **Bağlı**: Connected. The switch is complete. The addon uses the new method; the saved e-mail and password are deleted.
- **Doğrulanmadı**: Not verified. The connection is set up, but Paraşüt has not accepted a request made over it yet. The row shows the reason. Meanwhile invoices go out with the e-mail and password.
- **Beklemede**: On hold. Invoice sending has stopped for a while. The row shows the reason.
- **Yeniden bağlanın**: Reconnect. Paraşüt has ended the connection. Click the **Yeniden Bağlan** button and approve access again.
- **Bağlı değil**: Not connected. There is no connection and no saved password. If the button is missing, save the Client ID, Client Secret and Firma ID fields first, then enable the addon.

**Doğrulanmadı** and **Beklemede** mostly share one cause. The Paraşüt user lacks the **Uygulama Entegrasyonları** (Application Integrations) permission, or the Firma ID (company ID) is wrong. Fix the cause, then click the **Bağlantıyı Test Et** (Test Connection) button.

The connection renews itself. When your scheduled tasks run, the addon refreshes it once a day. A connection that is never renewed for 30 days ends, and you connect again.

## Tasks

### Installing the package

1. Back up these two files: `coremio/modules/Addons/Parasut/Parasut.php` and `coremio/modules/Addons/Parasut/views/settings.php`.
2. [Download the package](https://wisecp.com/files/wisecp-3.1.9.8.2-parasut-oauth.zip) and extract it into the folder where WISECP is installed. Only these two files are overwritten.
3. The extracted files get permission 644. Restore the previous permission if your server needs a different one.
4. Open the addon settings screen. The package is installed when the **Paraşüt Bağlantısı** row reads **Eski yöntemle bağlı**.

### Applying at Paraşüt and saving the details

1. Copy the address on the **Paraşüt Bağlantısı** row with the **Kopyala** (Copy) link.
2. On [Paraşüt DevHub](https://devhub.parasut.com), file an API application with the **Paraşüt Kullanıcısıyım** option. Enter the copied address in the **Redirect URL** field. Add both addresses if your site also opens with www.
3. When the application is complete, enter the values you receive in the **Client ID** and **Client Secret** fields of the settings screen. The Firma ID stays the same.
4. Click the **Save** button. Your current connection is not cut; the row still reads **Eski yöntemle bağlı**. While the old Client ID is saved, the **Paraşüt ile Bağlan** button is not shown and the row shows a warning; the button appears after this save.

### Connecting with Paraşüt

1. In Paraşüt, go to **Ayarlar** > **Kullanıcılar** > **Düzenle** and turn on the **Uygulama Entegrasyonları** permission of the user who will connect.
2. On the settings screen, click the **Paraşüt ile Bağlan** button. Sign in at Paraşüt and approve access.
3. You return to the settings screen. The switch is complete when the row reads **Bağlı**.

### After upgrading to WISECP 5

1. After the upgrade, check the connection row in the settings of the Paraşüt addon.
2. If the row does not read **Connected**, click the **Connect with Paraşüt** button. The same Client ID and the same address stay valid; no new application is needed.

## Things to Watch

> **Connect before December 10, 2026**
> 
> An installation that has not connected with the new method by then cannot transfer or formalize invoices at Paraşüt. If that date arrives while the row reads **Doğrulanmadı**, the addon drops the old method and uses the new connection. If the cause is still there, invoice sending stops until it is fixed.

> **Paraşüt does not change addresses later**
> 
> The Redirect URL cannot be changed after the application. A new application is needed if your domain changes.

> **Going back**
> 
> If you click the **Bağlantıyı Kes** (Disconnect) button while the row reads **Doğrulanmadı**, the addon keeps working with the old method. To remove the package, restore the two files you backed up. If you go back after the row reads **Bağlı**, you enter your e-mail and password again.
