You can download any type of file, public or controlled, as long as:\n\n* it resides in your project\n* you have copy permission\n* and proper authorization\n\nTo download a file using DRS API:\n\n1. [Create](doc:create-a-new-project) a new project.\n2. For the purpose of this example we will  [add a public file](doc:copy-files-to-a-project) by accessing  the **Public files** tab and searching for `example_human_reference.fasta`.\n3. [Copy the file](doc:copy-files-to-a-project) to your project. In addition:\n * The DRS ID is equal to the file ID on the Seven Bridges Platform (5dc018a9e4b0bf4ae31e92fc for this one).\n * The file ID is an integral part of the URL once you access the page with file details).\n * The DRS endpoint is https://cavatica-ga4gh-api.sbgenomics.com/ga4gh/drs/v1/\n4. Obtain the authentication token from: https://cavatica.sbgenomics.com/developer#token and include it in the API call.\n5. Perform the API call:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"'$ curl -H \\\"Authorization: Bearer <token>\\\" 'https://cavatica-ga4gh-api.sbgenomics.com/ga4gh/drs/v1/objects/5d728923e4b09cae86687385'\\n\",\n      \"language\": \"json\"\n    }\n  ]\n}\n[/block]\nThe response will contain the `access_id` parameter, which you will use within the API call for retrieving the URL for downloading the file. \n\n6. Perform the API call for obtaining the URL using the '`access_id`.\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"'$ curl -H \\\"Authorization: Bearer <token>\\\" 'https://cavatica-ga4gh-api.sbgenomics.com/ga4gh/drs/v1/objects/5d728923e4b09cae86687385/access/aws-us-east-1'\",\n      \"language\": \"json\"\n    }\n  ]\n}\n[/block]\nThe response will contain the URL for downloading the file. \n\n7. Download the file.","updates":[],"order":3,"isReference":false,"hidden":false,"sync_unique":"","link_url":"","link_external":false,"_id":"5dc1579fd355b4017257f562","project":"5773dcfc255e820e00e1cd4d","version":{"version":"1.0","version_clean":"1.0.0","codename":"","is_stable":true,"is_beta":false,"is_hidden":false,"is_deprecated":false,"categories":["5773dcfc255e820e00e1cd51","5773df36904b0c0e00ef05ff","577baf92451b1e0e006075ac","577bb183b7ee4a0e007c4e8d","577ce77a1cf3cb0e0048e5ea","577d11865fd4de0e00cc3dab","578e62792c3c790e00937597","578f4fd98335ca0e006d5c84","578f5e5c3d04570e00976ebb","57bc35f7531e000e0075d118","57f801b3760f3a1700219ebb","5804d55d1642890f00803623","581c8d55c0dc651900aa9350","589dcf8ba8c63b3b00c3704f","594cebadd8a2f7001b0b53b2","59a562f46a5d8c00238e309a","5a2aa096e25025003c582b58","5a2e79566c771d003ca0acd4","5a3a5166142db90026f24007","5a3a52b5bcc254001c4bf152","5a3a574a2be213002675c6d2","5a3a66bb2be213002675cb73","5a3a6e4854faf60030b63159","5c8a68278e883901341de571","5cb9971e57bf020024523c7b","5cbf1683e2a36d01d5012ecd","5dc15666a4f788004c5fd7d7","5eaff69e844d67003642a020","5eb00899b36ba5002d35b0c1","5eb0172be179b70073dc936e","5eb01b42b36ba5002d35ebba","5eb01f202654a20136813093","5eb918ef149186021c9a76c8","5f0839d3f4b24e005ebbbc29"],"_id":"5773dcfc255e820e00e1cd50","__v":34,"createdAt":"2016-06-29T14:36:44.812Z","releaseDate":"2016-06-29T14:36:44.812Z","project":"5773dcfc255e820e00e1cd4d"},"category":{"sync":{"isSync":false,"url":""},"pages":[],"title":"DRS API","slug":"drs-api","order":24,"from_sync":false,"reference":false,"_id":"5dc15666a4f788004c5fd7d7","project":"5773dcfc255e820e00e1cd4d","version":"5773dcfc255e820e00e1cd50","createdAt":"2019-11-05T11:00:54.262Z","__v":0},"user":"566590c83889610d0008a253","createdAt":"2019-11-05T11:06:07.004Z","__v":0,"parentDoc":null}
