# Before Starting

you'll need to:

* <mark style="color:blue;">Facebook Apps</mark> : Containers for all kinds of Facebook ad functions that you create.
* <mark style="color:blue;">Access Token</mark> : You can get system user access token or user access token with long validity period .
* <mark style="color:blue;">Permissions</mark> , depending on how you use the API.
* <mark style="color:blue;">Ad Account</mark> : You need an ad account to manage access to your ads, billing settings and spending limits. The account number can be found by going to Ad Account Settings within Ads Manager.

## **With Sandbox mode**

you can make all Marketing API calls against a sandbox ad account and get appropriate responses from the API. Facebook does not delivery any ads created in this sandbox mode and you will not accumulate impressions or spend.
