SignalZen API Authentication

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

Every SignalZen API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your SignalZen 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 SignalZen connection in Connections. SignalZen uses an API key. You generate the key in your SignalZen 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 SignalZen account that should run the action. MindCloud stores and refreshes the SignalZen 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 Users with an SignalZen connection looks like this:

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

Connect SignalZen API Secret

You need access to the SignalZen website whose backend data you want to read. This guide uses the API Secret documented in SignalZen's backend API docs.

  1. Sign in to your SignalZen Console

    Open your SignalZen account for the website you want to connect and go to the website settings area.

  2. Open the Integration (General) page for that website

    SignalZen's API docs say the API Secret key is available on the Integration (General) page of your website.

  3. Copy the API Secret

    Copy the API Secret exactly as shown. This is the value used in the Authorization bearer header for backend API requests.

  4. Paste the API Secret into the MindCloud connection

    Use the API Secret as the only backend credential for this wrapper. Keep the public token out of this connection because it is not part of the backend API auth contract.

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.
