401 Error: Authentication credentials not found.

Developer Support APIs & Integrations

Dear hubspot community,

I am writing because I am experiencing some strange problem. Yesterday I wrote a small python script to get the “feedback_submissions” data from one of our hubspot accounts.

It worked fine and I could retrieve data normally.

Today I tried again to retrieve the same data (the script did not change at all) and I got the 401 error (see code and error below).

Can anyone help me understand what can be happening?

The code I am executing is the following:

import hubspotfrom pprint import pprintfrom hubspot.crm.objects.feedback_submissions import ApiExceptionclient = hubspot.Client.create(access_token="my_access_token")try:api_response = client.crm.objects.feedback_submissions.basic_api.get_page(limit=1, archived=False, properties=['hs_sentiment', 'hs_survey_type'])print(api_response)except ApiException as e:print("Exception when calling basic_api->get_page: %s\n" % e)

In my case, the variable “my_access_token” has the actual access token that I get when I created the private app within my hubspot account, with the correct scopes.

And the error I get is:

Exception when calling basic_api->get_page: (401)

As said, yesterday it worked and now it does not without changing the code.

Thanks in advance!

Hi.

How about try this?

Quote: README

# client = hubspot.Client.create(access_token="my_access_token")
client = HubSpot(access_token='your_access_token')

This method may not be suitable.

def create(cls, **kwargs):
 return cls(**kwargs)

Thanks.

Hi @skimura ,

I have also tried the method you suggest and also this variation:

from hubspot import HubSpot

api_client = HubSpot()
api_client.access_token = 'your_access_token'

but it does not work either.

As I said, yesterday it worked fine and today it does not. I cannot figure out why.

@PMunar

I tried your code and it worked.

Is your `hubspot-api-client` is latest?

In my case, same error happned.

So I updated the library version.

`pip install --upgrade hubspot-api-client`

I ran it again and it was successful.

Please check library version.

If it’s not the latest version, try updating it.

Thanks.

Hi!

It turned out it was due to some libaray issue. Your suggestion regarding an update to the hubspot api library made me think about it.
