File Upload Limit Enforcement

Threat Lookup API version 1.1 was enhanced with the ability to enforce file uploads based on the license limits.

For more details, see the API Guide.

There are two options for enforcing the File Upload limit, depending on your licence preference:

  • An indication is returned when the file upload limit was reached, and additional uploads are prevented
  • An indication is returned when the file upload limit was reached and additional uploads are allowed
