# Connecting selling partner accounts

In order to start receiving seller/vendor data, the app requires an API connection authorization through "login with Amazon" (LWA).

{% hint style="warning" %}
Advertising manager/partner users do not have the ability to grant selling partner API access. Only primary accounts or user accounts with 'Selling Partner Appstore' permissions can grant authorization.
{% endhint %}

Prior to attempting to authorize a connection, ensure your selling account access level is sufficient, otherwise your attempt to establish a connection will fail. 

If you don't have the required credentials:

* Ask the primary owner or a user with a higher level access to [authorize the connection](#authorizing-a-connection).
* Request an upgrade to your permissions, then [authorize the connection](#authorizing-a-connection) yourself. Detailed instructions for granting the appropriate credentials can be found in the [granting 'app authorization' section](/getting-started/onboarding/connecting-accounts/connecting-selling-partner-accounts/granting-account-performance-dashboard-access.md):

{% endcontent-ref %}

### Authorizing a connection

Follow the steps below to establish a connection between your advertising account and the app:

* [x] Visit the "login with amazon" URL(s) provided by your Advertising Beast representative. The URLs will be similar to the examples below, according to the assigned server allocation:
  * `https://{{subdomain}}.app.advertisingbeast.com/lwa/sp/seller/na`
  * `https://{{subdomain}}.app.advertisingbeast.com/lwa/sp/vendor/eu`
* [x] If prompted, log into your amazon account using the credentials from your primary selling account.

* [x] Submit your consent to establish a connection.

{% hint style="success" %}
Once a successful connection has been established the app database will start populating with selling data for [advertising enabled](/getting-started/onboarding/enabling-accounts-for-advertising.md) accounts.
{% endhint %}
