Universe API Authentication

How to authenticate Universe API requests: one Bearer API key plus a connectionId. MindCloud runs the OAuth flow and refreshes Universe tokens for you.

Every Universe API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your Universe 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 Universe connection in Connections. Universe uses OAuth. When you create the connection, you are redirected to sign in to Universe and approve access — MindCloud stores the resulting tokens and refreshes them automatically, so your integration never has to.
  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 Universe account that should run the action. MindCloud stores and refreshes the Universe 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 Get Viewer with an Universe connection looks like this:

curl --request POST \
  --url "https://connect.mindcloud.co/v2/universal/apps/universe/actions/get-viewer/run" \
  --header "Authorization: Bearer $MINDCLOUD_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "connectionId": "$CONNECTION_ID",
  "arguments": {}
}'

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

Connect your Universe account

You need a Universe account and a Universe OAuth application that uses the MindCloud callback URL.

  1. Sign in to Universe

    Use the test Universe account so you can create and authorize the integration app.

  2. Open OAuth Applications

    Create or open the Universe OAuth application for this MindCloud app.

  3. Confirm the app credentials

    Verify the Client ID, Client Secret, and Redirect URI match the values prepared for the MindCloud Universe app.

  4. Authorize the connection when prompted by MindCloud

    MindCloud will open the Universe consent screen and return you to the configured callback URL.

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.
