Hey secops123 - Be sure to grab your ASM keys for this to work via the Advantage portal.

Check this out - https://docs.mandiant.com/home/asm-how-to-delete-an-asm-project.

1. Run the following curl command to get the project uuid.
   

   curl --location --request GET 'https:\\
   //asm-api.advantage.mandiant.com/api/v1/projects' \\
   --header 'INTRIGUE_ACCESS_KEY: {{intrigue_access_key}}' \\
   --header 'INTRIGUE_SECRET_KEY: {{intrigue_secret_key}}'

2. Using this uuid, run the following command to delete the project.
   

   curl --location --request DELETE 'https:\\
   //asm-api.advantage.mandiant.com/api/\\
   v1/projects/{{uuid}}' \\
   --header 'INTRIGUE_ACCESS_KEY: {{intrigue_access_key}}' \\
   --header 'INTRIGUE_SECRET_KEY: {{intrigue_secret_key}}'

Hope this helps.
