Database structure:

Tip: Even though we use Airtable in this tutorial as our data source, you can use any third-party backend tool you want to store the data.

Comments list

GET https://api.airtable.com/v0/TABLE_ID/Comment?filterByFormula={Posts}='${caption}'

Displays the list of comments associated with each post.

Query Parameters

Name	Type	Description
filterByFormula	string	Filters data based on specific field values

200

filterByFormula explained

• {Posts} = name of the table linked to this table

• ${caption}= the input variable that determines which data from the Comments table is displayed.

In this case, we want to display the comments specific to each post - and the "caption" column is how we differentiate each post.

This input variable "caption" must match the "Name" (under "Selected Data") of the corresponding data path in the Home feed request - this way the two requests link together.

Selected data from the GET: Home feed request.

As we have an input variable in the request URL, we need to input a test value in order to retrieve data. Under Test Values panel, input this:

Key	Value
caption	Bread matters (or any existing caption from the table)

Hit Send to send the request. Under Received Data, select the following 2 data paths in the screenshot below.
