Breaking Down the Code

The code snippet provided is a cURL command that makes a POST request to the pdfRest Convert to PDF API endpoint. Here's what each part of the command does:

-X POST

This specifies the HTTP method for the request, which is POST in this case, indicating that you are creating or updating a resource.

"https://api.pdfrest.com/pdf"

This is the URL of the API endpoint that handles the conversion to PDF.

-H "Accept: application/json"

This header tells the server that the client expects a response in JSON format.

-H "Content-Type: multipart/form-data"

This header indicates that the request body will be sent as multipart/form-data, which is necessary for uploading files.

-H "Api-Key: xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

This header includes your API key, which is required for authentication with the pdfRest API.

-F "file=@/path/to/file.jpg"

The -F flag is used to specify each field that will be sent as part of the multipart request. In this case, it's the JPG that you want to convert, with the path to that file on your system.

-F "output=example_out"

This field specifies the name of the output file after conversion.
