HTTP get file
Downloads a file from an HTTP endpoint into memory as a byte array.
Use this action when you need to fetch a file — for example a PDF, image, Excel workbook or CSV export — from a URL or an HTTP API, so it can be processed or stored by the rest of the Flow. The action sends an HTTP GET request to the specified URI and returns the raw response body.
Example 
This flow uses HTTP get file to download a PDF invoice from a supplier's API, converts it to an editable Word document, and uploads the result to Azure Blob Storage for further processing.
Properties
| Name | Required | Description |
|---|---|---|
| Title | No | The title of the action. |
| Authentication | No | The authentication configuration to use if the endpoint requires it. Supports Basic Authentication, OAuth 2.0 Client Credentials and Bearer token. |
| URI | Yes | Select or enter the URI of the file to download. You can use Flow variables or Workspace Variables to build a dynamic URI. |
| Query parameters | No | Key/value pairs that are appended to the URI as a query string, for example format=pdf. |
| Headers | No | Key/value pairs that are sent as HTTP request headers, for example Accept: application/pdf. |
| Return variable name | Yes | The name of the variable containing the downloaded file. Default: fileData. |
| Description | No | Additional notes or comments about the action or configuration. |
Returns
Returns the response body as a byte array.
The byte array can be passed directly to any action that accepts file data, such as Upload Blob, Upload file, or HTTP send file.
Note
This action returns only the file contents. If you need access to the HTTP status code or response headers, for example to read the file name from the Content-Disposition header, use the HTTP request action with the response content type set to Byte array instead.

Generate a PDF file with tabular data
This video shows how to generate a PDF file with tabular data using the Adobe PDF Services API, and download the generated file from an InVision Workbook.
It uses the HTTP trigger and Return File HTTP Response actions to handle the request and return the file.
