DHIS2 Tracker Tables and DHIS2 API

Hi everyone,

May I ask where are tracker values stored in the DHIS2 database. Reason I’m asking is I have created a python program to import data from a excel file into tracker. The imports the data successfully but the data is not showing on the tracker list and I don’t where is it stored in the database. What I know is that the data is there in the database because when I retrieve it, it shows from the IDE console. Here is my python code:

import requests
from requests.auth import HTTPBasicAuth

# Define the DHIS2 server URL and API endpoint for tracker data import
url = 'http://localhost:8081/dhis/api/trackedEntityInstances'
url_1 = 'http://localhost:8081/dhis/api/trackedEntityInstances.json?ou=z1YInlQ16D7'

# Define the headers with authentication and content type information
headers = {
    'Content-Type': 'application/json',
    'Authorization': 'Basic <base64_encoded_username_password>'
}

username = 'username'
password = 'password'

# Define the JSON data for import
json_data = {
    "trackedEntityType": "EWEsyuHlIvA",
    "orgUnit": "z1YInlQ16D7",
    "attributes": [
        {
