FAQ

Questions CNJ Datajud owners ask.

  • 01

    How do I find a process if I only have the CNJ number?

    Use the search_process_by_number capability. You will need the unformatted digits of the process and the specific court alias (e.g., api_publica_tjsp for São Paulo State Court).

  • 02

    Can I list multiple processes from a specific court organ?

    Yes, use search_processes_by_class_and_organ. Provide the court alias, the procedural class code, and the organ code. You can also control the result size and use pagination.

  • 03

    What is the 'Advanced Search' capability for?

    The search_processes_advanced capability allows you to send a raw Elasticsearch query body. This is useful for complex filtering that isn't covered by standard search capabilities, such as filtering by specific dates or nested metadata.
