# Form input parameters
## Form input parameters
To pass parameters via URL to a form, we need to define a variable or add a component to which we want to pass this parameter.
In the application edit view, in the left menu, we select the option **Input parameters**, and then **Add input parameter**. As the value **Alias** we provide the name of the injected variable alias. **Alias** will be part of the URL address to the application page. As **Request component** we choose a field from the application or a session variable. We can also assign it a default value that will be used if the parameter is not passed in the URL.

### **Ways to pass parameters**
1. Providing the parameter directly in the URL address:\
\
{% hint style="danger" %}
**Passing the parameter**
The parameter must be passed correctly in the address. Correct example: [http://platform-address/?parameter=value#/application-name](http://adres-do-platformy/?parametr=wartosc#/nazwa-wniosku). The parameter must be before #.
{% endhint %}
2. Providing the parameter as a hidden input field:
```
```
