Initiating Document Download Using BoldSign API

The first step in downloading a completed eSignature document via the BoldSign API is to initiate the download request. This requires the document ID of the specific document you wish to download. BoldSign supports a REST API, so you can use any server‑side programming language to call the endpoints.

Code Snippets

cURL

curl -X GET 'https://api.boldsign.com/v1/document/download?documentId={Your document Id}' \
-H 'accept: application/json' \
-H 'X-API-KEY: {your-api-key}'

C#

var apiClient = new ApiClient("https://api.boldsign.com", "Your API-KEY");
var documentClient = new DocumentClient(apiClient);
var documentStream = documentClient.DownloadDocument("{Your document Id}");

Python

import requests

url = "https://api.boldsign.com/v1/document/download?documentId={Your document Id}"
headers = {
    "accept": "application/json",
    "X-API-KEY": "{your API key}"
}
response = requests.get(url, headers=headers)
print(response.text)

Node.js

const axios = require('axios');

const response = axios.get('https://api.boldsign.com/v1/document/download', {
  params: { documentId: '{Your document Id}' },
  responseType: 'stream',
  headers: {
    accept: 'application/json',
    'X-API-KEY': '{your API key}'
  }
});

PHP

'application/json',
    'X-API-KEY' => '{your-api-key}'
];
$request = new Request('GET', 'https://api.boldsign.com/v1/document/download?documentId={Your document Id}', $headers);
$res = $client->sendAsync($request)->wait();
echo $res->getBody();

Handling the Document Stream

After initiating the download request, BoldSign’s API returns a document stream containing the completed eSignature document. You can process this stream according to your application’s needs—for example, saving it to a local file system, integrating it into another system, or displaying it to the user.

Conclusion

Downloading completed eSignature documents via the BoldSign API is straightforward and can be seamlessly integrated into your workflows. By leveraging the API, you can automate document retrieval, streamline processes, and improve the overall user experience.

Refer to the BoldSign API documentation to get started with integrating BoldSign APIs into your application.
