This document describes the mechanism via the REST API method with using curl commands. You can use what programming language you are familiar with to implement the API usage.

Request and implement credential

...

1. Send email to support@wmda.info with a PGP/GPG public key.  Or if you have other secure way to communicate the credential, please identify that in the email. Below we provide guide how can you generate PGP public key
2. WMDA will provide you the credential and send email to notify you.
3. You test the credential is working and can upload a file call endpoint in sandbox system. You can follow the steps below at "Implementation of Generating Bear Token" and  "Using the REST API" to test the credential:
   1. Implement the credential.
   2. Refresh Bear upload user guide below.

...

Guide to generate PGP/GPG key:

• Use command-line:
  https://www.gnupg.org/gph/en/manual/c14.html

• Use windows based tool Kleopatra
  
  

Implementation of Generating Bear Token

Data Manager uses Bear Token for the authorization as all WMDA API services, please follow user guide for API authentication to implement https://share.wmda.info/x/8I7RFw.

Update credential because of expiration

WMDA API credential is only available for one year currently. If your credential is expired, please send to WMDA support team to request a new one. 
Currently, WMDA is implementing a new feature to let API user to request a new credential by themselves before the credential expires, we will send announcement when this feature is available.

...

Below is an example to guide how to upload a filelist ion(s) that you have access:

Step 1: Set up the credential by following the instruction above in the "Implement credentialImplementation of Generating Bear Token" 

Step 2: Test to use the API in WMDA Data Manager sandbox. 
            Below is an example to guide how to get the information to upload a file:

no request body needed

Content-Type

application/json

Step 3:

Run curl call as below to get the ion(s) you have access.  You may get one or multiple ions based on your access permission.
"-i" option can be used to check the details of the communication if something go wrong.

curl -i 'https://sandbox-datamanager-api.wmda.info/api/v1/ions/list' \
--

...

header '

...

Authorization: Bearer ••••••' \
--

...

...

Content-Type

...

multipart/form-data

header 'Content-Type: application/json'

For windows user, please use double quote instead single quote for the reqest:

curl -i "https://sandbox-datamanager-api.wmda.info/api/v1/ions/list" \
--header "Authorization: Bearer ••••••" \
--header "Content-Type: application/json"

Upload

Below is a suggestion for curl call based on the Data Manager swagger doc to upload a file for an ION. 

curl

Step 3:

Run curl call as below to upload a file:

curl -i POST 'https://sandbox-datamanager-api.wmda.info/api/v1/files/upload' \
--header 'Authorization: Bearer ••••••' \
--header 'Content-Type: multipart/form-data' \
--form 'file=@c:@/path/to/file/ION-0999-D.gpg' \
--form 'ion="9999"' \
--form 'folder="upload"'

Upload

Below is a suggestion for curl call based on the Data Manager swagger doc 

Something to be aware of for windows based cmd:

1. please use double quote instead single quote for the request.
2.  Line break "\" dose not work, so use the curl script in one line, or use specific break that works for your script.
3. Use "\" to escape the double quote for the value.
4. The path separator for the file dose not matter, both Linux used "/" and windows used  "\" works.

curl "

curl -i POST 'https://sandbox-datamanager-api.wmda.info/api/v1/files/upload'" \
--header '"Authorization: Bearer ••••••'" \
--header '"Content-Type: multipart/form-data'
" --form '"file=@c@C:/path/to/file/ION-0999-D.gpg'" \
--form '"ion=\"9999\""' \
--form '"folder=\"upload\""'

Download

Download reports

You may use the API also to fetch your reports . And 2 steps are needed. 
For windows based cmd syntax, please see the example in the "Upload" part.

1.Fetch the files list and get the file names.

Use the following curl and endpoint file list API to fetch an array of file list for the folder "report"report:

curl --location 'https://sandbox-datamanager-api.wmda.info/api/v1/files/list' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ••••••' \
--data '{
  "ion": 9999,
  "folder": "report"
}'

...

2.  Fetch all the reports or the one you need.

Use the file download API to download the file you needed. You can only download one file a time. 

curl --location 'https://sandbox-datamanager-api.wmda.info/api/v1/files/download' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ••••••' \
--data '{
  "ion": 9999,
  "folder": "report",
  "fileName": "<filename>.txt"
}' \
--output <filename>.txt

Download full dataset

For those registries that are permitted to use the full dataset the statement below will fetch that. You can download the file in the folder "download"

curl POST --location 'https://sandbox-datamanager-api.wmda.info/api/v1/files/download' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ••••••' \
--data '{
  "ion": 9999,
  "folder": "download",
  "fileName": "wmda_data_v22.zip.gpg"
} \
--output wmda_data_v22.zip.gpg

Guide for troubleshooting of API usage

Q: I get 401 error when using endpoint?

A: This means you do not have access to the endpoint or you did no provide the token correctly. Please double check whether you have extra space or miss space for the parameter "Authorization: Bearer <token>". And if you confirm that and still get 401, please contact support@wmda.info.

Q: I see 403 error for endpoint upload/download, what is next step?

A:  If you can call the endpoint of ions/list, and then get 403 error for upload/download, most possible is because the request body is invalid. Please double check whether any single or double quote or options are wrongly used.
