Cannot get an access token - unknown grant type

Hi,

I am trying to get access token for a user, but I keep receiving "status":"BAD_GRANT_TYPE","message":"missing or unknown grant type". I have tried encoding query params or passing them as one json param, but nothing worked.

payload = {
 'grant_type': 'authorization_code',
 'client_id': 'f6***',
 'client_secret': 'f2***',
 'redirect_uri': 'https://sc***/',
 'code': '5f***'
}

requests.post('https://api.hubapi.com/oauth/v1/token?', params=payload)

@esthom Are you setting your content-type in the headers? Should be

Content-Type: application/x-www-form-urlencoded;charset=utf-8

Sometimes not having the correct content-type can throw off a server trying to read your request.

@pmanca I seem to be having the same issue. Not sure why however. the header on postman is as you describe it along with the body data.

header image: Screen Shot 2017 10 27 at 18 53 25 hosted at ImgBB — ImgBB
body image: Screen Shot 2017 10 27 at 18 53 38 hosted at ImgBB — ImgBB

Any ideas would be greatly appreciated.

thx

@sphot Can you send along the full image of your body?

Hi, I’m having the same problem with Postman, how could you solve it?

But not working for me even after chnaging the order as follows:
grant_type=authorization_code
&client_id=xxx
&client_secret=xxx
&redirect_uri=https://api.hubapi.com/contacts/v1/lists/all/contacts/all
&code=code_here

And adding " Content-Type: application/x-www-form-urlencoded;charset=utf-8"

esthom:

having the correct content-type can throw off a server trying to read your request.

I am facing this problem, even though supplying the required params in the header and request body respectively as follows:

ContentHeader


Body

Here’s the error I face:

Thanks @pmanca, that worked fine!

Welcome, @brij.

Per this documentation, you must include grant_type, client_id, client_secret, redirect_uri, and code in the request body.

You are trying to include those parameters as headers, but the only header should be Content-Type: application/x-www-form-urlencoded;charset=utf-8.

Not it says "{
“status”: “BAD_CLIENT_ID”,

“message”: “missing or unknown client id”,"

I think it worked now I have to get new client id.

But the same client id was used to get the code.

Hi, I am encountering similar issues with the curl response. In POSTMAN I am able to get a successful response, but when I replicate the settings in PHP with cURL, I am getting a “BAD_GRANT_TYPE” response.

Content Type should be set properly in the request. But I notice in the curl response, it shows content_type = application/json, is that correct?

Do you have any suggestions? Thanks

Hi, @brij.

Are you still experiencing this error? I was unsure whether your last post said you got it working.

The client_id you should use is located in your app settings. If you need help finding this, please share your developer Hub ID and app ID.

It worked now, please remove my last response.

Glad to hear it, @brij! I’ve deleted the post you requested.

@Isaac_Takushi Thanks a lot!
