Set request parameters

Query parameters are key-value pairs added to URLs that help modify what data an API returns. They appear after a question mark in the URL, like ?ticker=IBM&includePrices=true. Many APIs use parameters to filter results, specify data formats, or control response details.

You can add parameters in two ways: manually type them directly into the URL input field, or use the Parameters tab for easier management and automatic URL formatting.

Before you begin

Make sure you've entered the complete API base URL and endpoint path in the URL input field. For example: https://api.coingecko.com/api/v3/coins/markets

How to manage query parameters

Add a query parameter

1. On the custom request screen, click the Parameters tab.

2. Click + Add to create a new parameter.

3. Enter the parameter name in the left input field and its corresponding value in the right input field.

4. The parameter will automatically be added to your URL with proper formatting.

5. Use the + icon next to the value field to insert table values from your Airtable base into the parameter.

6. Repeat steps 2-5 to add additional parameters as needed.

Remove a query parameter

1. On the custom request screen, click the Parameters tab.

2. Find the parameter you want to remove.

3. Click the - button next to that parameter to delete it.

4. The parameter will automatically be removed from your URL.

Benefits of using the Parameters tab

Using the Parameters tab instead of manually editing the URL offers several advantages:

• Automatic formatting - Data Fetcher handles URL encoding and proper parameter syntax

• Easy management - Add, edit, or remove parameters without manually editing the URL string

• Dynamic values - Easily insert Airtable table values using the + icon

• Error prevention - Reduces mistakes from manual URL construction
