# Data Sources (Workflow)

Adloop imports data stocked in outside apps thanks to our **Data Sources** .

The Ad Sources are **Data Sources** connected to Ad platforms.

### Add a Data Source

Adding a Data Source, nothing simpler! In the Data Source page, you just have to click on the button, a popin with the available connections appears.

![](/files/RN7nW2nEPZj2KzMykkrD)

You can search the connection by its name.

A small label appears on some **Data Sources** :

\| ![](/files/JHiqI26TWFDUUJbTZHzv) | New connection | Super fresh, it has been there less than a month! | | ![](/files/7QhYVYoaEBV5gA0XQP28) | In progress | It will come rather soon. If you think it is taking too long, write to [**support@adloop.co** ](mailto:supper@adloop.co)to speed it up! | | ![](/files/j7eBG6WWxMrDmxzpQ8CN) | Premium | Our state-of-the-art connections, you need a Premium subscription to use it. |

### Connection types

Before connection a **Data Source** , you must have a access rights.

Each **Data Source** uses a specific connection mode, but there are 3 main types:

| **Connection type** | **Detail**                                                                                             |
| ------------------- | ------------------------------------------------------------------------------------------------------ |
| Oauth               | Delegation connection system. Adloop inherits reading authorisation for data.                          |
| Token API           | You will have to enter an API key you got from the ad platform itself or through your account manager. |
| Login / Password    | Simply login and password for an Adloop user you will have created in the ad platform.                 |

### Dimensions and Metrics choice

Once the connection is effective, you have to choose the \[\[ **Dimensions** |Dimensions-in-Adloop]] and the \[\[ **Metrics** |Metrics-in-Adloop]] we have to get from the **Data Source** .

The **default Dimensions** or the **default Metrics** will be imported no matter what, because they are main elements of our reports. It is not possible to delete them.

The **Other dimensions** and the **Other metrics** can be selected if you need them.

noteIf you don’t find a Dimension or a Metric, ask the Adloop Support!

If you don’t find a Dimension or a Metric, ask the Adloop Support!

### Imported period and import frequency

Adloop imports a year of data when a **Data Source** is added.

Once added, data are updated every 3 hours or 8 times a day.

Depending on the **Data Sources** and the API quotas, importing a year of data can take between 2 and 72 hours. Sometimes, you have to be patient!

### Data Quality

See our page dedicated to \[\[ **Data Quality** |Data-Quality]].
