Order data is automatically synchronized to Site.pro, making work easier — you only need to activate the integration by following the steps provided in the instructions.

1. Create operations
2. Link the newly created operations with a series
3. Create service cards
4. Download the plugin and install it in the e-shop administration module:
• Click on “Downloads” and choose ZIP version No. 2.3 https://bitbucket.org/b1cloud/b1-opencart/downloads/?tab=tags or version No. 3.0 https://bitbucket.org/b1cloud/b1-opencart3/downloads/?tab=tags;
• Install the plugin in the e-shop administration module. Requirements and installation instructions: https://bitbucket.org/b1cloud/b1-opencart3/src/master/.
5. Configure the e-shop parameters and connect Site.pro with OpenCart:

Set the initial parameters in the Site.pro program.

Settings → Integrations → API

After entering the module, click the “+ Add service” button.

• General settings:
“Name” — the name API1 will be set automatically, but you can change it to any name you prefer. Example: change it to OpenCart.
• Accounting settings:
• Fill in the fields marked with an asterisk and assign previously created operations and cards.

• The field “Sales operation for EU private individuals” is filled in when the company is registered in the OSS system and it is necessary to separate sales to private individuals from the EU.
• The field “Apply the highest VAT rate from order data (for discounts, delivery and other services)” is used when goods are subject to the customer’s country VAT rate, while delivery and discounts are 0%. The function automatically applies the highest VAT rate to all invoice lines so that manual corrections are not required.
• In the section “Product / service attributes”, select which product attributes you will use. Click the product / service attribute on the right or “Move all”, and the record(s) will be moved to the left. They will be marked with a green checkmark.
• Used VAT rates:
• In the field “Used VAT rates”, click the “+ Set VAT rates” button and fill in the fields. The VAT rates you define in the “VAT rate import” table will be assigned to each country. VAT rate configuration is mandatory.
• After filling in the specified fields, click the “+ Import” button. Once VAT rates are saved, check that they are correctly assigned to each country.
Note. If you have been assigned an additional VAT payer code and are entitled to sell with a different VAT rate, add the relevant information separately for that country, i.e. describe the other VAT rates used.
• After configuring all parameters, click the “Save” button at the top. The system will generate an API key and password for you. The generated API key and password must be entered in the e-shop.
• Set the initial parameters in the OpenCart store.

It is very important to pay attention to the settings, as they determine which data will be updated in Site.pro / the e-shop. OpenCart → Site.pro Configure. In the OpenCart store, click Modules & Services → Modules & Services. In the “Filter by” option, select “Installed Modules” and Site.pro “Configure”.

• Set the field values:
1. E-shop ID: an identification number generated automatically; it does not need to be changed. It is used to identify orders in the Site.pro program: Warehouse → E-commerce module.
2. Sync orders from: specify the date from which orders from the e-shop will be generated into the Site.pro program. There are no date restrictions.
3. Confirmed order status ID: set the status with which orders will be sent to the Site.pro program.
4. Sync Site.pro quantities with e-shop: select “Enable” if you want product stock levels in Site.pro to be updated in the e-shop when an order is placed.*
5. Try to write-off: select “Enable” if you want the product to be written off when an order arrives in the Site.pro program. This will happen automatically if the product is in stock and product codes are linked.*
6. Try to sync-price: select “Enable” if you want the product price in Site.pro to be automatically synced with the product in the e-shop. In the Site.pro product card, specify the price with VAT and without VAT.
7. Try to sync-name: select “Enable” if you want product names to be synchronized in both Site.pro and the e-shop during product synchronization.*
8. VAT tax rate: (field removed). The functionality has been moved to the Site.pro program. In the module Settings → API, field “Used VAT rates”, select by country.
9. Try to sync invoices number and series: select “Enable” if you want invoice numbering during order processing to match the numbering in the e-shop.
• Fill in the remaining fields in the e-shop according to the information in the Site.pro program:
1. API key: enter the API key obtained in the Site.pro program: Settings → API, field “API key”;
2. Private key: enter the API key password obtained in the Site.pro program: Settings → API, field “API password”;
3. Access key: the access key is generated automatically in the OpenCart system;
Note: For all configured parameters in the e-shop to work and for Site.pro products to be updated, the SKU code of products in the e-shop and in the Site.pro system must match: Directories → Products → Product cards, field “Code”.
• Import of product cards into the Site.pro program:
1. Import products to Site.pro (BETA): to copy product cards from the e-shop into the Site.pro accounting program, you can configure product card import.
2. Attribute (product attribute): select the product attribute with which you want to import product cards.
3. Measurement (unit of measure): select the unit of measure with which you want to import product cards.
After filling in the fields, click “Update” and then “Run”. Only product cards with a code will be imported into the Site.pro program.

After selecting all parameters, click the “Save” button at the top.
6. Link Site.pro and OpenCart products:

Directories → Product cards → Products

Link Site.pro products with OpenCart store products, i.e. enter the SKU product code from the OpenCart store into the “Code” field of the Site.pro product card. The code can consist of up to 60 digits.

Note. If product cards are linked in Site.pro and OpenCart, when the second record is created (i.e. the warehouse write-off document), the product will be written off.
7. Run commands in the e-shop
8. Order synchronization:
• Orders from the OpenCart e-shop are synchronized to Site.pro only with the status specified in the OpenCart system in the “Confirmed order status ID” field (under CONFIGURATION).

Which orders are imported:

• Synchronized orders from the OpenCart store appear in Site.pro modules: Warehouse → E-commerce. If the record is marked in grey, the order has been processed, i.e. the product has been written off from the warehouse. If the record has a white background, the product has not been written off. This action can be performed manually.

• You can see which records are registered in the Site.pro system in the “Accounting information” card. The field “Sales document series and number” shows the sales document that will be registered in accounting. The field “Write-off act document series and number” shows the write-off document that will be registered in accounting. These generated documents are registered in the modules: Warehouse → Trade with corresponding accounts. Clicking the “View” button opens the document in the “Warehouse” module.
• In the “Warehouse balances” section, you can see the remaining quantities of products in stock. If you see a record in this section, it means the product has not been written off.
