Certn API

Get your access token

To follow this guide, you need a demo account. Make sure it's fully set up according to our instructions on how to request a demo account.

Send a request

‌To communicate with our API, you'll need to build HTTP requests. You can use the programming language of your choice to achieve this. We provide examples of scripts using Python
, but most of the content you'll work with will be in JSON

Get your API access token

‌To gain access to our API, you will need your Client ID and Client Secret. Instructions for getting these values can be found in Use the API. You should take special precautions to keep your client secret a secret. In the example below (using our demo environment https://demo-api.certn.co), we show you how you can use secrets stored in a .env file.
First, make a request to get your access token. This token will be required to make all other API requests. For this step, make a GET request to our /token/ endpoint. If you're new to HTTP requests, visit W3Schools
for useful guides.
import requests
from dotenv import dotenv_values
# An example of how to manage your Client ID and Client Secret, using a .env file
secrets = dotenv_values(".env")
client_id = secrets["CLIENT_ID"]
client_secret = secrets["CLIENT_SECRET"]
# add the
headers = {
"Content-Type": "application/x-www-form-urlencoded"
body = {"grant_type": "client_credentials"}
# url to retrieve your access token
url = "https://demo-api.certn.co/token/"
# Send the HTTP request to the API via POST,
# including your Client ID and Client Secret for authentication
response = requests.post(
auth=(client_id, client_secret),
# retrieve the access token
access_token = response.data.get("access_token")
With everything set properly and a good internet connection, you should receive a response.status_code of 200 OK. The response.data object should look something like:
200 OK
"access_token": "string",
"expires_in": 36000,
You'll need this access_token as a bearer token in headers for all requests to our API. Let's see how to use this to Understand your general resources.
