# Case study : offering an eBook

For information, **it is not possible to put a product at 0€**.

If you want to **offer a product** such as an eBook, there is a solution :

Instead of going through the "Products" tab, you can **use the CTA** (Call to action) button in the settings. Indeed, you will have a button that will appear on the app of your customers, by clicking on it, they will be redirected to the link provided.

To create a CTA, in your back office **settings**, click on "**Call to action buttons**". If you have already created one, scroll down to the bottom of the page and click on "**+ Add**".

Next, you need to fill in the **information for your CTA**:

* **Link** : the link to which you want to redirect your customers
* **Image** : Choose your own image or one from the AZEOO database

Remember to click on "**Activate**" so that the CTA is visible on the app.
