Importing data into the DMP consists of four steps: uploading, mapping, matching and enabling. The steps per phase are described below: 


Please note that it may take up to several minutes before your uploaded data is available in the interface.

  1. Select an existing data source or create a new data source. 
  2. Upload the desired file. This can be a .TSV file, .CSV file, semicolon separated, pipe-separated or Newline separated JSON objects. The maximum file size is 100 MB and the file should be UTF8 encoded. You are able to upload one file at a time. The file must contain at least 2 rows. 
  3. Select a pixel to which the data will be assigned to. 
  4. When you proceed to the next step, it take can up to several minutes before the upload is completed. You will be notified by email and in the platform once the upload is completed.

The 2nd step of importing data allows you to map the incoming data to (existing) data in the DMP. This way data from multiple sources will be combined as one attribute, making the data in the DMP clearer and easier to use. You have three options for mapping the data: 

  • Map the source column to an existing attribute in the DMP. Select an existing attribute in the destination attribute dropdown to map the data to each other. You can only map source columns to custom attributes.
  • Create a new title for the source column. This can be done by typing the new name in destination attribute field. New title is displayed in brackets in case the attribute name is not yet in the system. 
  • Choose not to map the source column. The attribute will not be available in the DMP. 

You can hover over information-icon to see more sample data of the attribute. 


When matching the data, you select which data will be used to match the users from the data import to the users in the DMP. You are able to match the attributes you have selected to map in step 2. 

  1. Set the matching weight for the attributes. The attributes you see in this screen are the mapped attributes, the matching you selected previously will automatically be displayed here. You can make a selection out of three matching weights: 
    1. Deterministic match: A 1 to 1 match to the user. Examples of deterministic match points could be customer ID, email address, etc. 
    2. Probabilistic match: A match with a high probability to be accurate. Examples of deterministic match points could be last name, address, postal code, license plate, etc. 
    3. Not used for user matching: This attribute will not be used to match users. It is still possible to enable the attribute in the DMP.

At step 4 you're able to choose which attributes should be visible in the DMP and in which part of the DMP the attributes should be visible.

Deterministic Matches

Due to privacy reasons you can not enable attributes which are being used to deterministically match users.

  1. Check the attributes you'd like to see in the interface of the DMP. You can enable the data in Custom Audience and Report Central. 
  2. After you click 'Save' the algorithm will start importing and process the data. The processing time of your import depends on various factors including, but not limited to the size of the file, the complexity of the data, etc. You will be notified once the import has been completed.
