How to Contact delete (All contacts) in Child BU

Question

Is there a way to do contact delete in Child BU? (All contacts)

I want to delete the Contact in bulk.

All marketing activities (Journey, e-mail sending, etc.) take place in Child BU.

I would like to delete the contact generated by marketing activities in Child BU from Child BU.

If there is no way to delete it from Child BU, I would appreciate it if you could also tell me how to delete Contact from Parent BU.

Please let me know how I can automate it using Automation studio such as query, SSJS, etc.

Answer 1

Contact Deletion would need to be performed in the Parent BU context.

You can manually delete contacts from Contact Builder in the Parent BU.

To run it in an Automation, you would need to rely on MC REST APIs. Check this Reference for the Contact Deletion REST API.

Although you'd need the OAuth credentials to be able to call the API and write it in SSJS for the Script Activity for your automation. Check this Reference for the Access token.

Above information is not a full solution but clues so you can research and can solve it by yourself.
