We only support requests in JSON format - Next-Gen API

[Chad Buser]

 

I have the API installed and it shows as running however, I keep getting these warnings when trying to authenticate,

 

POST  https://mgmt-ip/mgmt/api/nextgen/v1/login

{
  "login": {
    "username": "nsroot",
    "password": "PASSWORD"
  }
}

Warning: Unable to verify the first certificate

{"errorcode":1500,"errormessage":"We only support requests in JSON format","details":[]}↵

 

Has anyone played with this yet?

For me it was two things - I was not sending the request in JSON format. It was in plain text.

And I was sending the creds in the JSON body and I still had Basic Auth selected on the Auth Tab - I set this to No Auth.

'Unable to verify the first cert' is just a warning since 'SSL Cert Verification' is off in the settings.

Add the Content-Type and Accept headers:

POST http://NetScaler/mgmt/api/nextgen/v1/login
Content-Type: application/json
Accept: application/json

{
  "login": {
    "username": "user1",
    "password": "verysecret"
  }
}

It did not work for me when specifying the CT and Accept headers only in the json body. 

 

"We only support requests in JSON format" Error code 1500 = missing Content-Type: application/json

"We only support sending responses in JSON format" Error code 1300 = missing Accept: application/json
