GMass API Authentication

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

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

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

Get your GMass API key

You need a GMass account and access to the GMass dashboard.

Open the GMass dashboard API key settings
Go to the GMass dashboard, click the Settings icon in the top right, then in the left panel open API Keys and choose Manage API Keys.
Dashboard → Settings → API Keys
Create or retrieve an API key
If you do not already have an API key, create a new one. If you already have one, you can reuse it or create a separate key for MindCloud.
Copy the API key
Use the copy control beside the key so you can paste it into the MindCloud GMass connection.

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.
