ClassMarker API Authentication

How to authenticate ClassMarker API requests: one Bearer API key plus a connectionId. MindCloud stores your API key securely — set it once, never resend it.

Every ClassMarker API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your ClassMarker account. This page covers both, plus exactly how to send them, so you do not need to visit any other page to get authenticated.

Steps to authenticate

  1. Create a MindCloud account at app.mindcloud.co if you do not already have one.
  2. Generate a MindCloud API Key in API Keys. This is the Bearer token you send on every request. Keep it on your server.
  3. Create a ClassMarker connection in Connections. ClassMarker uses an API key. You generate the key in your ClassMarker account, then paste it in when you create the connection — MindCloud stores it securely and never returns it in a response.
  4. Copy the connection’s connectionId — you will send it on every request alongside your MindCloud API Key.

How requests are authenticated

Authentication has two layers. Your MindCloud API Key authenticates the request to MindCloud, sent as a Bearer token in the Authorization header. The connectionId selects the connected ClassMarker account that should run the action. MindCloud stores and refreshes the ClassMarker credentials behind that connection, so you never send provider tokens with your requests.

Pass connectionId in the query string for GET and DELETE actions, and in the JSON body for POST, PUT, and PATCH actions.

For example, calling List Available Groups Links and Exams with an ClassMarker connection looks like this:

curl --request GET \
  --url "https://connect.mindcloud.co/v1/universal/classMarker/latest/actions/list-available-groups-links-and-exams" \
  --header "Authorization: Bearer $MINDCLOUD_API_KEY" \
  --get \
  --data-urlencode "connectionId=$CONNECTION_ID"

The Authorization: Bearer <your MindCloud API Key> header authenticates you to MindCloud; the connectionId tells MindCloud which ClassMarker account to run the action against. Missing or invalid Authorization returns 401, and a missing or mismatched connectionId returns 400.

Connect ClassMarker API

You need a ClassMarker account with API access to the groups or links you want this connection to read or manage.

  1. Open your API key settings in ClassMarker

    Sign in to ClassMarker, then go to My Account > Webhooks / API Keys and open the API Keys tab.

  2. Create a new API key

    Click New API Key +, enter a name, keep the key active, and set any optional validity dates you want.

  3. Choose what this key can access

    Select whether the key should access all groups and links or only specific groups and links. The data available in MindCloud will be limited to whatever this key can access.

  4. Save the key and copy both values

    When you save, ClassMarker generates an API key and its matching API secret. Copy both values now and paste them into the MindCloud connection form as API Key and API Secret.

Keep your key safe

Keep your MindCloud API Key on your server; do not ship it in browser code, mobile apps, public repositories, or logs. Anyone with the key can call the Universal API as your MindCloud account, across every connection you have created.
