BigML API Authentication

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

Every BigML API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your BigML 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

Create a MindCloud account at app.mindcloud.co if you do not already have one.
Generate a MindCloud API Key in API Keys. This is the Bearer token you send on every request. Keep it on your server.
Create a BigML connection in Connections. BigML uses an API key. You generate the key in your BigML account, then paste it in when you create the connection — MindCloud stores it securely and never returns it in a response.
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 BigML account that should run the action. MindCloud stores and refreshes the BigML 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 Sources with an BigML connection looks like this:

curl --request POST \
  --url "https://connect.mindcloud.co/v2/universal/apps/bigML/actions/list-sources/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 BigML account to run the action against. Missing or invalid Authorization returns 401, and a missing or mismatched connectionId returns 400.

Connect your BigML credentials

You need an activated BigML account.

Create or access your BigML account
Sign up if needed, then confirm the activation email sent by BigML.
Sign up
Sign in to BigML
Open the login page and enter your account credentials.
Login
Copy the BigML username and API key
From account/settings, copy the BigML username handle and API key. Do not use your email address in the Username field.
Paste values into MindCloud
Enter BigML Username (not email) and API Key in the connection form. Fill Project ID and Organization ID only when your workspace requires them.

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.
