Click Add integration.

Select MailWizz from the list of apps.

The MailWizz Sign in pop-up opens.
​

Enter MailWizz API URL and API key into the corresponding fields and click Save.

Click the Accept button to give Claspo permission to access the data in your MailWizz account.
​

​NOTE:
- The MailWizz access permission does not expire and remains valid unless you revoke it.
- If you experience authorization issues, click Reauthorize beside the MailWizz icon on the integration page and repeat the authorization process.

​

Select the list from the List dropdown menu. You have to select the list that you created in MailWizz with the fields you want to map to Claspo.

NOTE:
- Claspo export field names must match the MailWizz field tags.
- If you use option fields in the Claspo widget, they have to match with the corresponding fields in MailWizz.

Map the Claspo fields in the left-hand side column to the MailWizz fields in the right-hand side column.
​
The Field mapping contains two types of fields:
- Widget fields: Those are the contact fields you add when editing a Claspo widget. For example, email, first name, last name, phone.
- System fields: Those are the fields used to pass the information of a contact, such as site language, browser, operating system, device, and other.

If you want to pass a static value in a field, click + Add static fields and enter the static field values and map them to the corresponding fields in MailWizz.
The static field values are the same for all the customers who subscribed using this widget.

Click Done.
The MailWizz integration adds to your widget.

Go to Widgets in the Claspo left-hand side menu.

Expand the dropdown list in the Status column beside the widget integrated with MailWizz and select Published.
