OC API calls

This page explains how to use the APIs to:

Find the API call time.
Check connection to OC.
Verify API based authentication

Why run these APIs?

When the 'OpenClinica Study Data Importer' job takes time (20-30 minutes), it becomes difficult to test the configuration and run the job to sync in the data.

Steps to run the APIs

Invoke API to get the token on the terminal.

curl -X POST \
--data '{"username": "demo_username", "password": "demo_password"}' \
-H "Content-Type: application/json" \
https://qlhc2.build.openclinica.io/user-service/api/oauth/token

In above code, ‘POST’ and ‘Content-Type’ will remain fixed.

Code that will vary

Server credentials: Username and password

Server URL: https://qlhc2.build.openclinica.io will be your OC server URL

https://qlhc2.build.openclinica.io: This URL comprises 4 parts, i.e., protocol, hostname, port, and path.

Protocol: Decides language used for communication between the client and the server.
Hostname: Server placement.
Port number: Optional; default 443 for HTTPS; 80 for HTTP
Path: Decides the location of the resource. When not specified, it is /

After invoking auth API, you will receive a token, as shown below.

Every time, you will get a new token when you run the auth API.

2. Invoke data API to get the study data

curl -X GET -H "Accept: application/xml" \
-H "Authorization: Bearer #1step_token" \
"https://qlhc2.openclinica.io/OpenClinica/pages/auth/api/clinicaldata/S_ISPY(TEST)/*/*/*?includeAudits=y&includeDNs=n&includeMedtadata=y&showArchived=n"

In the above code, the 'GET' and 'Authorization' will remain fixed.

Code that will vary

Token: #1step_token token from #1 step

Server URL: https://qlhc2.build.openclinica.io OC server URL

Study Name: S_ISPY(TEST) study OID from the OC.

After Invoking data API, you will know how much time it takes to download study data.

Once you get the API’s time, you can inform the OpenClinica team to resolve the issue.
