How can I determine which purposes should be linked to my vendors in my specific case?

To determine which purposes should be linked with your vendors, you should consider the following points:

1. Understand the Nature of the Vendor: Identify what services the vendor provides and what data they collect. 
2. Consult Legal and Compliance Teams to understand the regulatory requirements related to data processing activities for your specific case. 
3. Vendor's Privacy Policy: Review the privacy policy of the vendor. Often, vendors will specify the purposes for which they process data.
4. Didomi Console: you can access the "Vendors & Purposes" section. Here, you have the option to select our default vendors, which come with purposes generally declared by the vendors themselves. 
5. Custom Purposes: If the predefined purposes do not fully cover the activities of your vendors, you might consider creating custom purposes. This can be done in the Didomi Console, where you can define and link these custom purposes to the appropriate vendors.
