4.5 How to compress a PDF document and reduce file size using API Rest


URL

To compress a PDF using our API Rest is necessary to perform a POST call to the following URL (ENDPOINT):

https://getoutpdf.com/api/tool/compress-pdf


GET Parameters

Our Rest API does not have operations via GET parameters


POST Parameters

  • api_keyApi key generated for your license. You can see your api key
    (string, required)
  • pdf_inSource PDF encoded in base64
    (string, required)

You can make a POST call using the HTML Header application/x-www-form-urlencoded, with the parameters described above.

Or you can send parameters via the JSON format, using the HTML Header application/json:

{
    "api_key" : "...",                  // string, required
    "pdf_in" : "..."                    // string, required
}

Example

{
    "api_key" : "64b5d1054b69e676b9984d8406c5209a6ba78...",
    "pdf_in" : "JVBERi0xLjQNJeLjz9MNCjYgMCBvYmo8PC9I..."
}

Response

If the operation is successful the response is a JSON with the following structure:

{
    "api_key": "...",       // string - Api key used for your license
    "pdf_base64": "...",    // string - PDF file encoded in base64
    "tokens_used": "...",   // integer - Tokens used in operation
    "tokens_left": "..."    // integer - Tokens left
}

Errors

If an error in sending parameters occurs, the response is a JSON with the following structure:

{
    "errors": {
        "param1": [     // string - Parameter name that generated the error
            "message"   // string - Error description
        ],
        "param2": [
            "message"
        ],
        ...
        "paramN": [
            "message"
        ]
    }
}

If a operation error occurs, the answer will be a JSON with the following structure:

{
    "errors": [
        "message1",
        "message2",
        ...
        "messageN"
    ]
}
