using curl with following command but unable to get any data than fault string

curl "https://staging.api.pearson.com/content/scapi/urn:pearson:manifestation:014f333d-ceda-476f-81f2-d3d6c89ace42"

Error that I am getting is :

{"fault":{"faultstring":"Failed to resolve API Key variable request.header.x-api key","detail":"errorcode":"steps.oauth.v2.FailedToResolveAPIKey"}}}

but when accessing the URL multiple times in Browser, I can able to get JSON data as desired

CURL woking code

curl "https://staging.api.pearson.com/content/scapi/urn:pearson:manifestation:014f333d-ceda-476f-81f2-d3d6c89ace42" -H "Accept:application/json"  -H "Accept-Encoding:gzip, deflate, sdch, br" -H "Accept-Language:en-US,en;q=0.8 " -H "Connection:keep-alive" -H "Host:staging.api.pearson.com" -H "X-ApiKey:7ij8zrLkCNR9DtAXx3KJ6yutoYnk4SAx" -H "X-PearsonSSOSession:AQIC5wM2LY4Sfczr6fmuhzvfN4dwnpK3c9K8tyduHkwg7sA.*AAJTSQACMDIAAlNLABQtNTk5Nzg3OTI1MTgxNTYxNjE3MAACUzEAAjAx*"

https://staging.api.pearson.com/content/scapi/urn:pearson:manifestation:014f333d-ceda-476f-81f2-d3d6c89ace42 does not work at browser too. https://screencast.com/t/vHK3UuKNu — Afzal Masood, Jun 08 '17 at 12:42
but I don't know how my chrome got that, anyway could you please go back and forth on the browser by modifying url, then you will get data automatically — Elambarathi Vimal Kannan, Jun 08 '17 at 12:45

As you said that in the chrome, it is working, on the successful request, you can copy as curl like below

sorry your image link broken – Elambarathi Vimal Kannan Jun 08 '17 at 12:52
the process showed in your image link shows error while running : {"fault":{"faultstring":"Failed to resolve API Key variable request.header.x-apikey","detail":{"errorcode":"steps.oauth.v2.FailedToResolveAPIKey"}}} – Elambarathi Vimal Kannan Jun 08 '17 at 13:07
You should do that after the successful request. As you said before that in the chrome it was working but not in curl. The above response only happens, if you copy and paste only url. As your chrome is already cached the API key, it was working. – Ravikiran Reddy Kotapati Jun 08 '17 at 13:11
I do not have an answer – Ravikiran Reddy Kotapati Jun 08 '17 at 13:14
Thank you so much Ravikiran ! – Elambarathi Vimal Kannan Jun 08 '17 at 13:15

curl "URL" \
 -H "Accept: application/json" \
 -H "x-apikey: {need to pass your API key here}" \
 -H "Content-Type: application/octet-stream"

Put your x-apikey in {need to pass your API key here}

Hi Ravikiran : got error as { "valid" : "false", "reason" : "App APIKey failed" } but it's a correct APIKey but how can chrome can show the data ? – Elambarathi Vimal Kannan Jun 08 '17 at 12:42
In the chrome goto developer tools and goto network tab, and check what is the api key header when it is successful in chrome – Ravikiran Reddy Kotapati Jun 08 '17 at 12:49
bit further, so now got 18 Response headers, should all have to be set while running curl ? – Elambarathi Vimal Kannan Jun 08 '17 at 12:58
You need to add request headers. When you follow steps in as per the image, it will only add request headers not response headers – Ravikiran Reddy Kotapati Jun 08 '17 at 13:01
There is only 3 request headers: (Provisional headers are shown, Upgrade-Insecure-Requests:1, User-Agent:M ) so, these are a valid ? – Elambarathi Vimal Kannan Jun 08 '17 at 13:05
That should be fine – Ravikiran Reddy Kotapati Jun 08 '17 at 13:06
got this error : {"fault":{"faultstring":"Failed to resolve API Key variable request.header.x-apikey","detail":{"errorcode":"steps.oauth.‌v2.FailedToResolveAP‌IKey"}}} – Elambarathi Vimal Kannan Jun 08 '17 at 13:10
can you copy the curl on the stackoverflow to see what you did? – Ravikiran Reddy Kotapati Jun 08 '17 at 13:12
Copied ! pls check – Elambarathi Vimal Kannan Jun 08 '17 at 13:17
I am not able to see the curl request what you posted – Ravikiran Reddy Kotapati Jun 08 '17 at 13:21
