File System API

The File System API allows you to perform the normal file system actions: create, update, move, copy, delete, download, and list information about files and folders. Since most use cases involve some basic file system operation, this is one of our core APIs.

URL Encoding

Note that the Path parameter in the API endpoints described below must be URL encoded in a special way. Each element of the path needs to be separately encoded. I.e. the forward slashes ('/') in the path must not be encoded, but the text in between must be. This is required because filesystem paths on Egnyte can contain characters which are not permitted in the path portion of a URL.

For example, this path: Shared/example?path/$file.txt should be encoded as Shared/example%3Fpath/%24file.txt

ID Based References

The URLs for each endpoint below uses paths to reference files and folders.  You may also reference files and folders using persistent IDs.

Files

  • For file details, the endpoint path would be /pubapi/v1/fs/ids/file/GROUP_ID
  • To download a file, the endpoint path would be /pubapi/v1/fs-content/ids/file/GROUP_ID
  • To download a specific version, the endpoint path would be /pubapi/v1/fs-content/ids/file/GROUP_ID?entry_id=ENTRY_ID
  • To delete a file, the endpoint path would be /pubapi/v1/fs/ids/file/{GROUP_ID}
  • To delete a specific version, the endpoint path would be /pubapi/v1/fs/ids/file/{Group ID}?entry_id={ENTRY_ID}
Note that in the Event API response, the entry_id is called the target_id and the group_id is called the target_group_id.

Folders

  • For folder details, the endpoint path would be /pubapi/v1/fs/ids/folder/FOLDER_ID

Copy File or Folder

Copies a file or folder.

POST /pubapi/v1/fs/{Full Path to File/Folder}
POST /pubapi/v1/fs/ids/{file or folder}/{ID}

Request Parameters

Parameter Description Required Possible Values
action Defines the action to be taken Yes Must be copy
destination Determines where the file/folder will be copied Yes Full absolute destination path of file or folder.  Note that if the destination path does not contain the original folder name only the subfolders and files within the folder will be copied.  For example, if the source folder is at "Shared/A" and you are copying to destination "Shared/B", all contents of folder A will be copied to "B"; however, if the destination is "Shared/B/A" the folder "A" will be created within "B" as well.
permissions Determines how permissions are handled as part of a folder copy. Permissions can either be copied (keep_original), or inherited from the destination folder (inherit_from_parent).

Please, note that if the destination folder already exists, then the value of the "permissions" parameter will be ignored and the existing permissions of the destination folder will not be changed.

For example, if the source folder is "Shared/A" and you are copying it to a destination "Shared/B/A" and this "Shared/B/A" folder already exists, the permissions set on the destionation folder will be preserved regardless of the value of the "permissions" parameter		 No keep_original, inherit_from_parent.  If neither is specified, the default behavior is to use the workgroup settings configuration, found at Configuration -> Security & Authentication -> Keep permissions on folder move & copy

Chunked Upload

The chunked upload flow provides a mechanism to upload large files.  Though not a firmly enforced requirement, we recommend using this flow for files larger than 100 MB. To upload files of smaller sizes, you can use the simpler upload flow.

POST /pubapi/v1/fs-content/{Full Path to File}
POST /pubapi/v1/fs-content/ids/file/{ID}

Chunked Upload process:

  1. Split file into chunks—recommended size is 104857600 bytes (100 MB) each.  The minimum chunk size is 10485760 (10 MB). The maximum chunk size is 1073741824 bytes (1GB).  All chunks should be the same size, except for the last chunk which can be any size.
  2. Start the process by uploading the first chunk. Save the X-Egnyte-Upload-Id header received in the response. Use the X-Egnyte-Chunk-Sha512-Checksum SHA512 hash in the response to confirm that each chunk was uploaded cleanly.
  3. Upload the rest of the chunks except the final one in any order. Use the X-Egnyte-Upload-Id identifier and X-Egnyte-Chunk-Num sequence numbers to uniquely identify each chunk. Upload chunks in parallel to get maximum throughput.
  4. When uploading the final chunk, indicate this by including the header “X-Egnyte-Last-Chunk: true”
  5. Chunks remain available for a period of 24 hours after the first chunk is uploaded.

Sample API Calls:

Upload the first chunk

Sample Request Body

<body containing binary data for first chunk only>

Upload all but the last chunk:

Use the same X-Egnyte-Upload-Id as the first chunk.

Optionally, you can upload a specific chunk again by repeating that chunk request. This might be useful if data if the X-Egnyte-Chunk-Sha512-Checksum returned indicates that the chunk has not been uploaded properly.

Step-specific Request Headers:

Header Description Sample Value
X-Egnyte-Upload-Id Upload identifier returned after uploading first chunk. To be used as a reference when uploading subsequent chunks. b2adfaf5-9f7d-49e5-a1ab-32389e1d1da6

Sample Request Body

<body containing binary chunk data for chunk specified by X-Egnyte-Chunk-Num only>

Upload last chunk and commit file

Client must indicate that it is uploading the last chunk by passing header “X-Egnyte-Last-Chunk: true”. Server will respond with HTTP Status 200 and ETag plus SHA512 hash for the entire completed file. Client should check hash for entire file to validate uploaded content.  Details on how to compute checksums are provided below.

Optionally, you can send a final 0-byte chunk to close the chunked upload flow.  This allows you to verify the final chunk succeeded before committing the file.

Step-specific Request Header:

Header Description Value
X-Egnyte-Upload-Id Upload identifier returned after uploading first chunk. To be used as a reference when uploading subsequent chunks. b2adfaf5-9f7d-49e5-a1ab-32389e1d1da6
X-Egnyte-Last-Chunk Indicates that chunk being uploaded is the last chunk. Must be true
X-Sha512-Checksum SHA512 hash of entire file that can be used for validating upload integrity. 6cb2785692b05c5eff397109457031bde7ab236982364cc7b51e319c67c463d7721c82c024ef3f74b9dff d388be6dc8120edc214e7d0eadaaf2c5e0eb44845a3
Last-Modified Indicates last modified date for file. Sun, 26 Aug 2012 03:55:29 GMT

Sample Request Body

<body containing binary chunk data for last chunk only>

Calculating the Checksums:

Calculating Checksums for Individual Chunks:

So let's say I have a file that is split into three chunks with checksums computed as follows.

$ openssl dgst -sha512 chunk1 
  SHA512(chunk1)= 886a81ec5f9e4f66aaa77d95ccb58dc6ca4000bfb12d13351adf8cd6fb09933e0e16d057983eb8a81fffc71d71f6fc5c1649d08b20b0dc30d64ea449850b4f41

  $ openssl dgst -sha512 chunk2
  SHA512(chunk2)= 8ae7b487d9ad803e0ad85dee9320a1c3203f021e2fffe07573588e2869f097589eaa97923d75ada6f84a5eaeb7ad63f7f0a0ddc1e78053f570b8a6363abcd9f3

  $ openssl dgst -sha512 chunk3
  SHA512(chunk3)= eef77c3e9fef9277e0a3bbc8a4faaf2727481296b3d6e0143c5c661d2cd1441eeccc54d4bc086c29ea3ee918a79dcba122bd077fe3232f30f54afc7ed452cc8d

After you upload each chunk, Egnyte will compute a SHA512 checksum for that chunk and return it in the X-Egnyte-Chunk-Sha512-Checksum header.  If the checksum does not match the checksum you compute locally, the chunk was corrupted and should be sent again.

When you have sent the last chunk, we will return another checksum in the response body that looks like:
2-3-10485761-41e3a616682407fd721ef2843ac5f3966c73ae2ef0bc00fc3d8c27d69327fc3d326ce64b13163cbc7664be3e1bc1a9f8bf4c1d257fdfdab20919edbc6813f30f
This follows the form:
{Version#}-{#Chunks}-{Chunk Size}-{SHA512(SHA512 of Chunk Checksums)}
The final checksum comes in three parts which are separated by dashes ("-"):
  • Version #: This is the version of the checksum response.  This guide is written for version 2.
  • # Chunks: This is the total number of chunks provided.
  • Chunk Size: This is the size of each chunk uploaded (except for the last chunk).
  • SHA512(SHA512 of Chunk Checksums): This is the checksum of checksums computed for the full file.

Calculating the Checksum of Checksums

In addition to checking that each chunk committed properly, you can also check to see if the entire file was properly transferred.

  $ echo -n $CHECKSUM1$CHECKSUM2$CHECKSUM3 | openssl dgst -sha512  
  
import hashlib
  m = hashlib.sha512()
  m.update("886a81ec5f9e4f66aaa77d95ccb58dc6ca4000bfb12d13351adf8cd6fb09933e0e16d057983eb8a81fffc71d71f6fc5c1649d08b20b0dc30d64ea449850b4f41")
  m.update("8ae7b487d9ad803e0ad85dee9320a1c3203f021e2fffe07573588e2869f097589eaa97923d75ada6f84a5eaeb7ad63f7f0a0ddc1e78053f570b8a6363abcd9f3")

  m.hexdigest()
These samples should all evaluate to the final section of the checksum we return after the last chunk:
