Upload

To initiate a file upload you need to execute a POST request against the /libraries/:id/files endpoint.

Two fields are available in the JSON body of the POST request:

• name - the name of the file. Required.

• folder_id - the id of the parent folder. Omit this field if the file is attached to the root of the library and not to a parent folder.

In the response you will receive a time-limited JWT token (expires in 15 minutes) and a target URL where you can upload the actual file bytes to.

1. Request to retrieve a token for upload and storage server URL

cURL

curl --request POST \
  --header "Content-Type: application/json" \
  --url https://api.digitalsamba.com/api/v1/libraries/8606721f-d847-4721-a5dc-6537e822104c/files \
  --user YOUR_TEAM_ID:YOUR_DEVELOPER_KEY \
  --data '{"name": "prom.jpg"}'

import java.net.http.HttpRequest;
import java.net.http.HttpResponse;

String TEAM_ID = "YOUR_TEAM_ID";
String DEVELOPER_KEY = "YOUR_DEVELOPER_KEY";
String authorizationHeader = "Bearer " + Base64.getEncoder().encodeToString((TEAM_ID + ":" + DEVELOPER_KEY).getBytes());

//Put your library id here - this value is just an example
final String libraryId = "8606721f-d847-4721-a5dc-6537e822104c";
		
Map<String, String> data = Map.of(
       "name", "Birthday Party"
);
String jsonData = new ObjectMapper().writeValueAsString(data);

HttpRequest request = HttpRequest.newBuilder()
  .POST(HttpRequest.BodyPublishers.ofString(jsonData))
  .uri(new URI("https://api.digitalsamba.com/api/v1/libraries/" + libraryId + "/folders"))
  .header("Authorization", authorizationHeader)
  .header("Content-Type", "application/json")
  .build();

HttpClient client = HttpClient.newHttpClient();
HttpResponse<String> response = client.send(request, BodyHandlers.ofString());

System.out.println("Status code: " + response.statusCode());
System.out.println("Body: " + response.body());

Response (200 OK)

}

2. Request to finish the upload

The POST request URL is the external_storage_url from the previous request.

You need to put the token from the first request into the Authorization: Bearer header.

The file is sent in a multipart request where the field name is "file".

curl --request POST \
  --header "Authorization: Bearer eyJ0eXAiOiJKV1QiL............." \
  -F "file=@prom.jpg"
