Get data from bubble database

I am getting data from the bubble database. I am using the swagger documentation to fetch data. However, I cannot filter the data I am fetching from the database. I am integrating my bubble web app with a mobile application.

Scenario: i have a transactions table with transaction details. How do I fetch all transactions of the logged in user.

When a user is logged in successfully, i would like to show that user all his transactions on the app. How do i go about that.
How do i make that API call.

If you add a constraints key to your URL params you can define an array of filters - documented here.

In Axios that would look like the below - but however you’re calling in you just need those constraints to end up in your GET request URL params:

    let constraintList = [{ "key": "_id", "constraint_type": "equals", "value": *id of user* }];
    const limit = 50;

    let response = await axios({
        method: 'get',
        url: *path to your Bubble app's data API*,
        params: { 'constraints': JSON.stringify(constraintList), 'limit': limit },
        headers: {
            'Authorization': 'bearer ' +*your auth token*
