## Beschreibung

**The easiest way to accept card payments in your WooCommerce store in Turkey.**
Enter the API credentials of your iyzico or PayTR account, enable the payment method,
and your customers pay with 3D Secure — in installments if they like. No license
key, no trial period, no per-transaction fee.

Invum POS is built around how payments work in Turkey: Turkish lira, installment
culture, BDDK installment limits and the banks‘ Turkish decline codes. When your
store grows and you want to move to your bank’s virtual POS, you don’t switch plugins;
you continue from the same panel.

#### ✨ What’s in the free version?

 * 💳 **iyzico and PayTR** — iyzico Checkout Form and Direct API; PayTR iFrame and
   Direct API. You can enable both at the same time and define several accounts 
   for each.
 * 🔒 **3D Secure** — Secure payment with bank authentication. Every result returned
   by the provider is verified by its signature and on the server; a fake „paid“
   notification cannot change your order.
 * 📆 **Installments** — Boxes on the checkout page showing the number of installments,
   the monthly amount and the total. Installment table on the product page. Separate
   rates per card family (Bonus, World, Axess, Maximum, CardFinans, Paraf…); pass
   the interest on to the customer or protect your net amount.
 * ⚖️ **BDDK installment limits** — The maximum number of installments allowed for
   each product group is applied automatically; no installments are offered on debit,
   prepaid and foreign cards.
 * ⚡ **One-click payment with saved cards** — The customer saves the card once 
   and pays with one click on later purchases. Card data is stored at the payment
   provider, not on your server.
 * 🔁 **Subscriptions** — Recurring payments with WooCommerce Subscriptions, including
   cancellation, suspension and card change flows.
 * 🔗 **Payment links** — For stores taking orders by phone or WhatsApp: enter the
   amount, send the link, the customer pays by card.
 * 🧾 **Turkish decline codes** — Clear messages such as „Insufficient card limit“
   or „The bank declined the transaction“; both you and your customer see what went
   wrong.
 * 📊 **Dashboard and transaction logs** — Success rate, weekly comparison, most
   used methods, filterable transaction history and CSV export.
 * 🎨 **Card form with live preview** — On both the WooCommerce Blocks and the classic
   checkout, a card visual that comes alive as the card number is typed.
 * ↩️ **Refunds** — Full or partial refunds through the provider with the „Refund“
   button on the WooCommerce order screen.

#### 🚀 Five-minute setup

 1. Install and activate the plugin.
 2. On the **Invum POS › POS Accounts** screen, choose iyzico or PayTR and enter your
    API credentials.
 3. Try it in test mode first; if everything works, turn test mode off. That’s it.

#### 🏦 Moving to your bank’s virtual POS?

When you want a direct bank virtual POS — to lower commission or to use your bank’s
installment campaigns — you install a separate plugin, **Invum POS Pro**, next to
this one. Your settings, saved cards and transaction history stay as they are.

 * **Pro** — every bank and provider: 12 banks on the NestPay infrastructure (Akbank,
   İş Bankası, Ziraat Bankası, Halkbank, QNB, TEB, ING, Şekerbank, Türkiye Finans,
   Anadolubank, Alternatif Bank, Cardplus), Garanti BBVA, Yapı Kredi (Posnet), VakıfBank,
   Craftgate and Moka. Payment routing rules by category, cart and bank.
 * **Studio** — advanced rules by card BIN and installment count; Paid Memberships
   Pro and GiveWP bridges.
 * **Agency** — 5 live + 5 test sites; moving a rule set from one store to another;
   delivering the plugin under your own brand name (white label).

The code of the Pro plugin is **not included** in this free plugin. Plans and pricing:
[invum.com.tr/pos](https://invum.com.tr/pos/)

#### 🛡️ Security

 * API keys are stored encrypted (AES-256) in the database; they are never kept 
   as plain text anywhere.
 * Card number and CVV are never written to logs under any circumstances.
 * With the iyzico Checkout Form and PayTR iFrame, card data never touches your 
   site (PCI DSS SAQ A). If you choose the on-site card form (Direct API), card 
   data passes through your server to the provider; your PCI scope is then SAQ D.
 * When you delete the plugin, your POS accounts and transaction history are kept
   by default.

#### Trademarks

iyzico, PayTR, Param, Garanti BBVA, Yapı Kredi, Posnet, VakıfBank, PayFlex, NestPay,
Craftgate, Moka and the bank names listed above are trademarks of their respective
owners. Invum is an independent product; it is not affiliated with, endorsed or 
sponsored by any of these companies. The names are used only to identify the payment
services this plugin connects to.

### External services

This plugin relies on the third-party services documented below. Payment gateways
and the license API are contacted only when you enable and configure them; the only
service refreshed automatically is the CBRT exchange rate feed (details below).

**Payment gateways (iyzico and PayTR in the Lite version; additional providers are
added by the separate Invum POS Pro plugin).** When a customer pays with a gateway
you have enabled, the plugin sends the data needed to process that payment — order
amount and currency, order/transaction IDs, and the card or 3-D Secure data entered
by the customer — to that provider’s API together with the merchant credentials 
you configured. This happens during checkout and when the provider sends back the
3-D Secure / payment result. Card data is never stored as plain text or written 
to logs. Each provider is operated independently; please review their terms of use
and privacy policy:

 * iyzico — Terms: https://www.iyzico.com/kendim-icin/kullanici-sozlesmesi — Privacy:
   https://www.iyzico.com/gizlilik-politikasi
 * PayTR — Terms: https://www.paytr.com/kosullar — Privacy: https://www.paytr.com/
   gizlilik

**CBRT exchange rate feed (www.tcmb.gov.tr).** A scheduled task fetches the official
daily exchange rates published by the Central Bank of the Republic of Türkiye once
a day from `https://www.tcmb.gov.tr/kurlar/today.xml` and shows them on the exchange
rate card in the plugin’s admin panel. This is a plain GET request for a public 
XML document — no personal data, order data or site information is transmitted. 
Terms/usage: https://www.tcmb.gov.tr/

**Invum License API (panel.invum.com.tr).** If you enter a Pro, Studio or Agency
license key, the plugin contacts the Invum panel to activate, verify or deactivate
that key and to receive Pro module updates. It transmits your license key and your
site address (URL). The free Lite version requires no license and makes no calls
to this service unless you enter a key. Terms: https://invum.com.tr/ — Privacy:

## FAQ

### Is it really free? Is there a limit?

Yes. You can use it with iyzico and PayTR on an unlimited number of sites with unlimited
transactions. There is no license key, trial period or per-transaction fee. You 
pay nothing beyond your payment provider’s own commission.

### Which versions are required?

PHP 8.1+, WordPress 6.6+, WooCommerce 9.0+. Your site must run over HTTPS (SSL) 
for 3D Secure returns.

### How do installments work?

When the customer types the card number, the card’s bank and family (Bonus, World,
Axess…) are recognized and the installments available for that card are shown as
boxes on the checkout page. You can pass the interest on to the customer or have
it calculated so that your cash amount is protected. The maximum installment limit
set by BDDK for each product group is applied automatically.

### Is card data stored on my site?

No. With saved cards, the card is stored in your payment provider’s (iyzico/PayTR)
vault; only a token is kept on your site. Card number and CVV are never written 
to logs under any circumstances. Your API keys are stored encrypted in the database.

### Is it compatible with WooCommerce Blocks (the new checkout)?

Yes. It works on both the Blocks-based checkout and the classic shortcode checkout.

### Does it work with WooCommerce Subscriptions?

Yes. With iyzico and PayTR Direct, recurring payments are charged automatically 
from the saved card; cancellation, suspension, reactivation and payment method change
are supported.

### Can I connect my bank’s virtual POS?

The free version works with iyzico and PayTR. The virtual POS of Akbank, İş Bankası,
Garanti BBVA, Yapı Kredi, VakıfBank, Ziraat and other banks, Craftgate and Moka 
require the separate **Invum POS Pro** plugin: [invum.com.tr/pos](https://invum.com.tr/pos/).
When you move to Pro, your settings and transaction history are kept.

### Will I lose my data if I delete the plugin?

No, your POS accounts and transaction history are kept by default. If you want to
delete everything, turn off the „Keep data when the plugin is deleted“ option under**
Invum POS › Settings**.

### How do I get support? What if a feature I need is missing?

Write to the [support forum](https://wordpress.org/support/plugin/invum-pos/); questions
and feature requests are answered there.

### Is it GPL compatible?

Yes, it is licensed under GPL-2.0-or-later; you can review and modify its source
code.

## Änderungsprotokoll

#### 1.0.32

 * Fix: WooCommerce Subscriptions — the card a subscription is bought with (a saved
   card, or the card saved during that payment) is now attached to the subscription.
   Before, the first automatic renewal could not find a saved card unless the customer
   changed the payment method by hand.
 * Fix: PayTR Direct — a card saved during payment is now stored on stores that 
   use only a PayTR Direct account; for subscription orders the card is saved even
   if the „save card“ box is not ticked.
 * Fix: Subscription renewals (WooCommerce Subscriptions and the membership, donation
   and course bridges) no longer fail with „No adapter resolved“ when the provider
   is not the store’s default account; a renewal is charged on the subscription’s
   own payment method and POS account.
 * Fix: PayTR Direct subscription renewals were sent to the PayTR iFrame integration,
   which cannot charge a saved card, and always failed; they are now charged through
   PayTR Direct.

#### 1.0.31

 * Security: Card-testing protection, the installment lookup limit and the payment
   provider call budget now count requests sent at the same time correctly; parallel
   requests could previously slip past the limits.
 * Security: Card-testing protection counts a logged-in customer’s attempts on their
   account instead of the billing email, so someone typing that customer’s email
   at checkout can no longer block them.
 * Fix: With several accounts for the same provider, the background job now checks
   an open 3D Secure payment on the account the order was charged with (PayTR, iyzico,
   VakıfBank, Craftgate, NestPay banks).
 * Fix: Pending orders of other payment methods no longer push this plugin’s orders
   out of the background job’s batch.

#### 1.0.30

 * Improvement (paid plans): Garanti BBVA and Moka payments whose customer closed
   the 3D Secure page are now checked with the bank by the background job; an order
   the bank has charged is marked paid and can be refunded from the plugin.
 * Fix: Orders placed through the main „Invum POS“ payment method were never checked
   by the background job for payments left open on the 3D Secure page.
 * Fix: The background job and a late bank callback could settle the same order 
   at the same time; they now take turns, and the job re-reads the order before 
   changing it.
 * Fix: An order whose earlier payment attempt was already closed by the bank callback
   is no longer re-checked using that attempt, and orders paid through the main 
   payment method are never cancelled by the background job.
 * Improvement: A PayTR payment confirmed by the background job is now refundable
   from the plugin, and is accepted only when nothing was refunded and the amount
   matches the order.

#### 1.0.29

 * Change (paid plans): Every bank and provider (Garanti BBVA, Yapı Kredi Posnet,
   VakıfBank, Craftgate and Moka, alongside the 12 NestPay banks) now opens on the
   Pro plan. Studio and Agency keep their advanced rules, bridges, extra sites and
   white label.
 * Improvement: The bank list on the Dashboard upgrade card is worded as a question
   and notes that it does not change your plugin settings.

#### 1.0.28

 * Improvement: On sites without a license, the Dashboard upgrade card now asks 
   for your bank and shows the plan that supports it, its yearly price (VAT included)
   and a direct link to the order page, together with the refund terms.
 * Improvement: 34 Turkish interface strings that still contained English words (
   endpoint, credential, gateway) were translated.
 * Fix: The „Learn about Invum POS Pro“ link on the new POS account screen pointed
   to a page that no longer exists; it now opens the plan comparison.

#### 1.0.27

 * New: A „▶ Watch the video guide for this screen“ link in the header of the screens(
   Dashboard, POS Accounts, Transaction Logs, Payment Links, Installment Compliance,
   Installment Display, Smart Rules and Simulator). Hidden on white-label sites.
 * Improvement: The plugin’s Documentation page lists the current guides and error
   pages (VakıfBank, PCI merchant guide, new error code pages); the retired Param
   was removed from the list.

#### 1.0.26

 * Fix: In the Payment Links list the status was shown raw as „pending“, „paid“;
   it now reads Pending, Paid, Expired, Cancelled.
 * Fix: Under the product lines on the order screen the plugin’s internal records(
   BDDK product group, store installment limit) were shown with raw key names; they
   are now hidden. The records were not deleted and remain as an audit trail.

#### 1.0.25

 * Critical fix (full version only, Moka): When Moka became „Moka United“ its server
   addresses changed; the plugin was calling the old addresses. The order field 
   in the 3D return was also read with the wrong name and successful payments could
   be marked „failed“. Payment, failed payment and refund were verified end to end
   with a real test account in the Moka United test environment.
 * Fix (full version only, Moka): „Test Connection“ calls the right endpoint; a 
   wrong password and a missing server IP permission are reported with separate 
   messages.
 * Fix (full version only, Garanti BBVA): Every payment attempt goes to the bank
   with its own order number. When a customer whose card was declined tried to pay
   the same order again, Garanti rejected it with „Only one sale is allowed within
   the same order“. Refunds and voids use this number; older orders are not affected.

#### 1.0.24

 * Security: Adding, editing and deleting POS accounts and testing their connection
   are now open only to site administrators by default. Shop Manager accounts can
   see them but cannot enter keys; transaction logs, payment links and reports stay
   available to Shop Managers. If you deliberately want the old behavior: `add_filter('
   invum_pos_manage_accounts_capability', fn() => 'manage_woocommerce' );`
 * Fix (full version only): „Multi-account routing“ was wrongly shown as locked 
   to the Agency plan on the Features page; the feature already worked on Pro and
   higher plans.
 * New: If the plugin has been useful, a WordPress.org review is requested once 
   on the plugin’s own pages after at least 10 successful payments and 14 days; 
   it can be dismissed with „Later“ or „Don’t ask again“. Never shown on white-label
   sites.
 * Improvement: The plugin’s display name is now „Invum POS Entegratör – Sanal POS
   ve Taksitli Ödeme“.
 * Fix: Direct-access protection in one plugin file was moved to where the WordPress.
   org check looks for it.

#### 1.0.23

 * Fix: PayTR saved-card payments and WooCommerce Subscriptions renewal charges 
   were sent with an order number format PayTR does not accept (with underscores);
   the charges were rejected before reaching the bank. The order number now contains
   only letters and digits as PayTR requires.
 * Security: Saved-card tokens returned in payment provider responses (iyzico cardToken/
   cardUserKey, PayTR utoken and similar) are now written to transaction logs masked;
   existing records are masked once on update. Masking also catches card numbers
   with spaces/dashes and card fields in XML / form bodies; log messages are masked
   too.
 * Security: Two payment notifications arriving at the same time for the same order
   are now reliably merged into a single transaction (the database lock is truly
   atomic).
 * Security: In the CSV export of transaction logs, values starting with „=“, „+“,„-„,„@“
   are not executed as Excel formulas.
 * Security: Live calls from the installment and BIN lookup endpoints to the payment
   provider are bound to a site-wide per-minute budget; empty responses are also
   cached briefly. When the budget is used up the customer only sees a single payment,
   checkout does not break (`invum_pos_upstream_budget_per_minute` filter).
 * Fix: A payment link counts as „paid“ only if the order carries a line for the
   link’s amount and is not cash on delivery.
 * Fix: When changing a subscription’s payment method, the selected saved card is
   verified to belong to the subscriber.
 * Fix: Leading/trailing spaces in API keys are trimmed on the POS account form (
   signature errors caused by copy-paste).
 * Security fix (full version only): The VakıfBank 3D Secure return was processed
   even without the verification ID sent by the bank; the ID is now required and
   must match the order’s record.
 * Fix (full version only): The „translation loaded too early“ notice logged on 
   every request on WordPress 6.7 and later was resolved.
