Invalid API Key

I cannot figure out how to get pass this on a create order API:

{"message":"Invalid API Key"}

They same key worked fine on the wallet get transactions api. I tried generating a new key, but getting the same error. What else can I try?

It’s possible you’re using the wrong api endpoint/url. I just ran into this issue trying to call functions from the exchange api when I needed to be using the Advanced Trading API

url = ""

I get invalid key.

url = ""

I get unauthorized.

What is the correct url? Too many conflicting docs.

Is there a working sample/code out there that includes the authentication and authorization along with creating an order?

Perhaps this is a simpler question: How do I modify the stock code below to include api key authentication?

import http.client

conn = http.client.HTTPSConnection("")
payload = ''
headers = {}
conn.request("POST", "/api/v3/brokerage/orders", payload, headers)
res = conn.getresponse()
data =

Hi, @firlas , can you please share your actual request?

I may have gotten further. Can someone tell me what this error means? …or point me to the error catalog?

6 days later, I’m hoping you figured it out. If not, do you have the right permissions set on your API key? For that request I believe you would want the BTC Wallet and Cash (USD) accounts enabled (or all), and the permissions should look something like this if you are going to be trading:


Looks like I have all those checked off:

What does “Source Account Not Tradable” mean?

ah, you were right jmicko. i had forgot to check my usd wallet. i got past that error. thank you.
