# Inline trials flow

In order to generate an Inline trial checkout cart, it’s mandatory to have the following parameters in the inline script.

## Mandatory parameters for the trial links

* **Signature**: for building a Trial buy link it is required to generate a signature
* **Price** (define trial price for the corresponding currency - 0 for free trial, higher than 0 for paid trial)
* **Period** (define period – not less than 7 days)
* **Currency** (define currency)
* **Product Code** (define the product for which the trial is applied)

How your script should look like:

```javascript
TwoCoInlineCart.cart.setCurrency('EUR');
TwoCoInlineCart.products.add({
                       code: 'ANTV_2016',
                       tperiod: 7,
                       tprices: {EUR: 5, RON: 20},
                  });
TwoCoInlineCart.cart.setSignature('520ba411696e37f1839145bfa793f7199d8d0295a228ea42dc20a3f39196e358');
```

### Limitations

* The trial period/price applies to a single product.
* The trial period can be a minimum of 7 days.
* 2Checkout uses the custom prices and ignores the per-product pricing configuration.
* Supported payment methods: credit and debit cards, PayPal, and Direct Debit.
* 2Checkout automatically converts the trial to a paid subscription when the trial interval expires by charging shoppers based on the payment-on-file information. Customers can opt-out at any time using their myAccount.
