Hello,

API stands for Application Programming Interface, the Shop module has some API end points to get the data from SMA. Please refer to documentation.pdf for more info.

PDF library, the selection will be used to generate pdf files for sales, purchases and quotations.

Use code for slug, the product and category slug (url port for SEO) will be generated from product/category name. But for some non english user those is not the option so they can use products/category code instead as slug for urls (only used for shop module).

Racks, is the product location in the warehouse. You can set rack on list products page after selecting the warehouse.

Thank you

**[Mian Saleem](/u/saleem)** Thanks. Can you please explain more about "Weighing Scale Barcode" which is in the system settings? (please explain each settings tabs)

The weighing scale setting is quite straight forward. I have attached the image.

Let me know what is not clear to you?

**[Mian Saleem](/u/saleem)** yes Thanks i got it, when i change it where can i see what i changed? is it going to my product barcode? can you please explain it!

Hello,

No, it has nothing to do with product barcode. The products code will stay same.

It's just to parse the weight scale barcode only.

Thank you

**[Mian Saleem](/u/saleem)** what do you mean by parse the weight? does this have a function for read white weight barcodes or print?

Hello,

Please read the full sentence, not 'parse the weight' but 'parse the weight scale barcode'

How the scale barcode will be parsed

```txt
1. by checking the barcode length is equal to the total chars for scale barcode in settings
2. If yes then only move forward otherwise return the code as it is
3. For yes, parse the barcode and get item code and quantity/price as per settings.
4. Find the product for the item code and set the quantity/price and return
```

If you see the live demo, there are 2 products with code `111111` and `222222` 6 chars and `F11111100250C` and `F22222200150C` will be parse with default settings as following

```
F 111111 00150/100 C
F 222222 00250/100 C
X item code quantity X
```

If you still have any concern, please let me know.

Thank you

Thanks for your helping
