LinkedIn has recently changed its policy regarding automatic certificate submission, so you will need to manually add the information for your certificate. You can follow these steps to add a DataCamp statement of accomplishment to your LinkedIn profile:

Share your statement of accomplishment as a post or private message:

1. Travel to your desired statement of accomplishment: Where can I download my statement of accomplishment?
2. Select the LinkedIn icon 
3. Select 'Share in a Post' or 'Send as private message'

Share your statement of accomplishment under LinkedIn's 'Licenses & Certificates'

1. Travel to your desired statement of accomplishment: Where can I download my statement of accomplishment?
2. Copy the statement of accomplishment's URL
3. Log in to your LinkedIn account and navigate to your profile page
4. Navigate to Licenses & Certificates and click on the + icon
5. Paste your DataCamp statement of accomplishment URL into the Credential URL field
6. Specify DataCamp as the certification authority
7. The credential ID is the last part of the URL (it is a long string of numbers and letters)
8. Add the name of the certificate, and click Save

More information on adding LinkedIn Certification can be found on the LinkedIn Help Center.
