**Note**
This topic is for administrators and developers with administration access rights in Shopware.
:::
This topic describes how to configure the newsletter subscription and unsubscription feature, if you are using Shopware as an e-commerce platform with Optimizely Campaign. The Shopware integration uses standard formulas that contain Shopware for newsletter registration. You cannot add fields.
:::hint{type="info"}
**Note**
See [Advanced configuration](docId\:dd6EVEsXWIY3PyZ_JzIoT) how to work with multiple sub-shops and language versions.
:::
To configure subscribes and unsubscribes, do the following:
1. Configure the [opt-in mailing](docId\:piVDtSUnmK1o5iawK3F7r) (registration confirmations) in Optimizely Campaign, then use a field function to reference the confirmation link to your shop.
2. Insert the [opt-in ID and the authorization code](docId\:piVDtSUnmK1o5iawK3F7r) (for recipient consent) in Shopware.
3. Enable the use of the [double opt-in method](docId\:piVDtSUnmK1o5iawK3F7r) in Shopware.
## [yT9R-configuring-subscribes-and-unsubscribes.mdx](docId\:piVDtSUnmK1o5iawK3F7r)Step 1. Configuring the opt-in mailing
1. Open the Optimizely Campaign menu and select **Campaigns** >**Opt-in processes**.
2. Select the opt-in process for the connection to your shop and click **Edit…**.
3. On the **Email** node, click **Properties** .
4. Click **Edit Content…**.
5. Click the name of the paragraph that contains the registration confirmation link.
6. In the **Text** area, click **Source**.
7. Replace the existing link with the following code lines or field functions:
```html
{Double-Opt-In-Link}?hash={customer-id}&shop-id={shop-id}&shop={shop}
```
:::Paragraph{indent="1"}
You can find the link that you need to replace between the \ tags in quotation marks.
**Example**
In the source code, the following link is contained in \ tags:
:::
```html
Confirm subscription
```
:::Paragraph{indent="1"}
Replace the link marked in red in quotation marks as follows:
:::
```html
Confirm subscription
```

:::hint{type="info" indent="2"}
**Note**
The Shopware integration accepts the referral (the call), and identifies the customer by the **hash** parameter and the store or subshop, using the **shop-id** and **shop** parameters, respectively.
:::
8. Click **Apply** > **Close** > **Save and close**.
## [yT9R-configuring-subscribes-and-unsubscribes.mdx](docId\:piVDtSUnmK1o5iawK3F7r)Step 2. Inserting the opt-in ID and the authorization code
For this step, you need to insert two values in your Shopware system:
- The opt-in ID used to record recipient consent. To see the opt-in ID, open the Optimizely Campaign [menu](docId\:PmNPgvNucBrAG5Rw8f41f) and select **Administration** > **API overview** > **Opt-in processes**.
- The authorization code for the recipient list that Optimizely customer support has generated to connect your shop. To locate this in Optimizely Campaign, select **Administration** > **API overview** > **Recipient lists** tab. Select the corresponding recipient list and click **Manage authorization codes**. If no authorization code is presently available for this recipient list, click **Create authorization code**.
:::hint{type="info"}
**Note**
Do not confuse the **recipient list** for your newsletter recipients with the transaction recipient list for your transactional mails. Customer support sets up two different types of recipient lists for the sending of newsletters and the sending of transactional mails (for example order confirmations, invoices).
