Hi John, What I've implemented on our local system is the user uploads their data, then automatically a workflow is run on that data (so the user doesn't need to select a tool to execute). I email the user once the job is complete with a link to that the user can download the results. I auto get the download results using the api i.e: ~/scripts/api/display.py api_key http://barium-rbh/capaibl/api/histories/1cd8e2f6b131e891/contents/f68b550c47... This returns something like: Member Information ------------------ accessible: True file_name: /export/barium-data3/galaxy-suvr/database/files/000/dataset_421.dat visible: True file_size: 521 file_ext: html id: f68b550c4724eeae misc_info: uuid: None download_url: /capaibl/api/histories/1cd8e2f6b131e891/contents/f68b550c4724eeae/display state: ok display_types: [] display_apps: [] misc_blurb: 521 bytes peek: <table cellspacing="0" cellpadding="3"><tr><td>HTML file</td></tr></table> data_type: html deleted: False history_id: 4181f0f3af1244e2 genome_build: ? hid: 120 visualizations: [] metadata_data_lines: 17 metadata_dbkey: ? name: Processing input data (0171-T0-AV45) model_class: HistoryDatasetAssociation purged: False api_type: file

From this I get the "download_url" and add the server name to it and an extension to get:

http://barium-rbh/capaibl/api/histories/1cd8e2f6b131e891/contents/f68b550c47... Which i add to the email. When the user clicks on it they are able to download the zipped up files. However, they can only do this after first login into Galaxy otherwise they get a "API Authentication Required for this request" error on the webpage.

"History -> Export to file" or is it via the API? Regardless, if you trust your users and want to disable security mechanisms I believe (and I could be wrong) you should be able to by finding the relevant controllers in Galaxy and changing either the decorator to allow anonymous access or changing the checks on the histories/datasets to disable checking if the supplied user is authorized. Though this will make everyones data available to everyone else (or the world if this is a publicly accessible Galaxy instance). -John On Wed, Jul 16, 2014 at 5:43 AM, <Neil.Burdett@csiro.au> wrote:

Hi, galaxy provides a download_url to download zipped up files. However, the user must first log into Galaxy to commence the download. Is there a way to turn this feature off, so that users can click on the link and download the data without first login

Thanks Neil
