Download Files Using API

This page shows you how to download a file using an API using PDF as the file format.

Prerequisites

• Access to a cloud platform with API endpoints.
• A Table widget to bind data and download files.

Download file using URL

To download a file using the file URL, follow these steps:

1. In the API configuration, specify the request method (GET) and provide your API URL, including any necessary path.

2. Configure the Table data property of the Table widget to bind the response of the API using {{download_image.data}} where download_image is the name of the query.

3. Set the widget's onRowSelected event to download a file corresponding to a selected row by pasting the following code where imageCatalog is the name of the Table widget:

   {{download_image.run(()=>download(imageCatalog.selectedRow.url,imageCatalog.selectedRow.fileName))}}

4. To test the download, click on any row on the table.

Download file using file data

To download a file using the file data, follow these steps:

1. In the API configuration, specify the request method (GET) and provide your API URL, including any necessary path.

2. In Headers, add the key content_type and enter the MIME type as its value. For example: application/pdf

3. Configure the Table data property of the Table widget to bind the response of the API using {{list_files.data}} where list_files is the name of the query.

4. Set the widget's onRowSelected event to download a PDF file from the API using the following code:

   {{list_files.run(()=>{download(list_files.data,"filename.pdf")})}}

   To decode an encoded file content, use the JavaScript atob() method.

   For example:

   {{list_files.run(()=>{download(atob(list_files.data),"filename.pdf")})}}

5. To test the download, click on any row on the table.
