Atera API Authentication

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

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

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

Connect your Atera API key

You need an Atera account with access to Admin settings.

Open the API page in Atera
In Atera, go to Admin on the left side, then open Data management > API.
Admin → Data management → API
Reveal and copy your API key
On the API page, click the eye icon to reveal the key, then copy it. Keep this key secret because it gives access to your Atera data.
Paste the key into MindCloud
Return to the MindCloud connection form and paste the copied value into the API key field.

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.
