HubSpot API (Private App) – "Authentication credentials not found" error

Developer Support APIs & Integrations
,
1

Hi! I’m trying to test the HubSpot API by making the following request with a Python script:

import requests
url = "https://api.hubapi.com/crm/v3/objects/contacts?limit=100&archived=false"
headers = {“authorization”: “Bearer MY_TOKEN”}
response = requests.get(url, headers=headers)
print(response.text)

But I’m getting this error:

{
“status”: “error”,
“message”: "Authentication credentials not found. This API supports OAuth 2.0 authentication and you can find more details at https://developers.hubspot.com/docs/methods/auth/oauth-overview",
“correlationId”: “019d7712-d98f-7622-ad7a-045a0bcb177b”,
“category”: “INVALID_AUTHENTICATION”
}

What should I check? I’ve already verified the token and it seems correct. I also checked the permissions granted when creating the private app (I gave it the “crm.objects.contacts.read” scope), so that looks fine too.

Is there anything else I should review?

Thanks, regards!

@YamilAli2 - I hope I can give you a good Pyton example here. I use these techniques almost every day in Custom workflow steps, so I have some conventions that work well for me.

Header setup - via a stored Secret.

 #Get the API key as environment variable
 api_token=os.getenv('CUSTOM_TOKEN')
 #API Request Headers
 headers = {
 'Content-Type': 'application/json',
 'Authorization': 'Bearer ' + api_token,
 }

GET call via requests:

 try:
 response = requests.request("GET", request_url, headers=headers)
 Jresp = response.json()
 except:
 print(response)

As long as you have set up required scopes any specific API URL in your Legacy/Private app/Service Keys , all should see a positive response.

Hope this is helpful.
