The Activity API returns data objects related to performance, history, and usage of file transfers in Aspera on Cloud.

Endpoints in the Activity API

Below are the endpoints for the Activity API. For detailed reference information, see API Explorer.

  • /application_events – Get data for individual events in Aspera on Cloud, such as a package being sent or a user being created.
  • /egress_throughputs – Get the data transfer rate for downloads (in bps) for the current user’s resource and ‘resource’ – the organization, node, user, or workspace
  • /file_access – Get all data for user access of files and folders in the Activity app.
  • /file_access/search – Get data for user access of files and folders in the Activity app, filtered by a search parameter. The response data is separated into “users” and “files” arrays.
  • /ingress_throughputs – Get the data transfer rate for uploads (in bps) for the current user’s ‘resource’ – the organization, node, user, or workspace.
  • /transfers – Get an array of all transfers for the current user’s specified ‘resource’ – the organization, node, user, or workspace – for the specified time duration.
  • /transfers/uuid – Get a transfer object for the unique identifier of the transfer session and ‘resource’ – the organization, node, user, or workspace.
  • /volume_usage – Get a list of bytes uploaded and bytes downloaded for transfers between the specified start and stop times.


To use the Activity API, the following must be true:

  • You have the Advanced Edition or Enterprise Edition of Aspera on Cloud.
  • You are enabled in the Activity App in Aspera on Cloud.

Enabling the Activity App

Access Control

The Activity API requires that a bearer token (JSON Web Token) be included in the header for each request. A bearer token is a type of OAuth2 authentication that includes a public key and a private key. In Aspera on Cloud, we create the bearer token with the Files API.

For detailed information on obtaining the bearer token, see the tutorial, Making a Request to the Activity API.

Here is an example of a bearer token:

Pagination of Query Results

The Activity API supports pagination of results in the response for all endpoints, with the exception of /volume_usage.

For the endpoints that support pagination, if an integer value is not specified for the limit parameter, each page of the response includes the default number of response objects. The default value varies by endpoint.

Use Cases
