“message”: “Api key and secret are required.”

I was just upgraded my account to Pro before this work.
is this cause?



Hi Noriko,


Looks like you are trying to pass api_key/secret as a JSON payload. v1 of the API takes them as query parameters or form data. Please try that.


Hi Joshua ,

thank you for your response.
i solved that issue.
but now i have a new error.

i send this url.
response is error 200
what is this cause?

[****************&api_secret=*********************]( &api_secret=***** )

“error”: {
“code”: 200,
“message”: “Invalid master account api key or secret.”



[****************&api_secret=*********************&]( &api_secret=***** &

“error”: {
“code”: 200,
“message”: “Invalid master account api key or secret.”



Looks like you are trying to use Master Account APIs. If your account is not setup this way, they will not work for you.


Hi Joshua ,

I’m confused.

I was thinking this account is master.

This account was created by me And  upgraded user type to Pro before few days.

How can i know Master Account APIs?(Where page?)

Do I need something to use this APIs?

This api_key gets here. 



Master accounts are a special type, they have the ability to create accounts (not users) underneath them. These type of accounts and that ability is usually preserved for resellers/partners.
