# Integrating File Sources with PDF.co
> Incorporating file sources such as Google Drive, Dropbox, OneDrive, and Box into your Zapier workflows is essential when working with PDF.co. This guide details the specific input properties from each of these services to be used with PDF.co’s Zapier plugin.
## URL Accessibility for PDF.co
The API supports TLS 1.2 and 1.3 for secure connections. Earlier versions such as TLS 1.0 and 1.1 are deprecated and should be avoided.
For successful integration, any publicly accessible URL can be used. Whether you’re using services like Google Drive, Dropbox, or others, make sure the URLs are accessible to PDF.co. We recommend using Zapier-generated URLs (detailed in the sections below) as they are guaranteed to be compatible with PDF.co. If you’re using direct URLs not provided via Zapier, please verify their public accessibility to ensure PDF.co can process your files efficiently.
## Google Drive
When integrating Google Drive with PDF.co in Zapier, use the File property to retrieve files. This property allows PDF.co to access the file needed for processing.
## Dropbox
**For Dropbox, the `Direct Media Link` property is utilized. However, it’s important to be aware of Dropbox’s file size limitation:**
* Limitation: Access to files is restricted up to 100 MB only. Larger files may result in an error.
## OneDrive
OneDrive integration requires the `Download URL` property. This is effective for accessing files and passing them to PDF.co.
## Box
Box, similar to Google Drive, uses the `File` property to share files with PDF.co. This ensures seamless file transfer within your Zapier workflow.
## SharePoint
For SharePoint, use the `Direct Download Link` property. Ensure the link is publicly accessible.
**Steps to Generate the Direct Download Link:**
**Add the “Microsoft SharePoint” Trigger**
* In SharePoint, add the **“New file in folder”** Trigger Event to create a shareable link that can be adjusted for direct access.
* **Site Address**: Select your SharePoint site.
* **Library Name**: Choose the library containing your file.
* **Item Id**: Specify the file you want to share.
For more information, see [Microsoft Docs on creating sharing links](https://docs.microsoft.com/en-us/connectors/sharepointonline/#create-sharing-link-for-a-file-or-folder).
If you are not using a Zapier trigger/action or encountering any issues, you can manually modify the link for access compatibility:
1. **Modify the Link for PDF.co Compatibility**
* Append `?download=1` to convert it into a direct download link compatible with PDF.co.
**Example:**
Original Link:
```
https://yourcompany.sharepoint.com/:b:/s/SharedDocuments/Ed1...4ig
```
Modified Link:
```
https://yourcompany.sharepoint.com/:b:/s/SharedDocuments/Ed1...4ig?download=1
```
2. **Troubleshooting**:
* Ensure the sharing settings allow public access.
* Test the link in a browser to confirm it downloads the file directly.
* Double-check permissions if PDF.co cannot access the file.
