Invoking REST/SOAP web services in OTM Cloud

Hi,

We have been provisioned with a OTM Cloud instance (v6.4.1) and I'm trying to run some tests to query data using the REST and SOAP services. I'm using cURL and Postman to test these services, but running into issues:

REST:

curl -i -v -X GET -u <username>:<password> -H "Content-Type: application/json" "https://otmgtm-test-<identity-domain>.otm.us6.oraclecloud.com/GC3/api/sdo/buy_shipment?id=D1.05261"

C:\Curl>curl -i -v --cacert "C:\Curl\otmgtm.jks" -GET -u <username>:<password> -H "Content-Type: application/json" "https://otmgtm-test-<identity-domain>.otm.us6.oraclecloud.com/GC3/api/sdo/buy_shipment?id=D1.05261"
