AgentX API Authentication

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

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

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

Connect your AgentX account

You need an AgentX account that can sign in at app.agentx.so and view an API key.

Open AgentX and sign in
Go to https://app.agentx.so and sign in with your AgentX account. If your account uses Google sign-in, choose Continue with Google and finish the login flow.
Open your account menu
After you sign in, open your account area from the AgentX app UI. AgentX's getting-started guide says your API key is available from the account menu after login.
Copy your API key
Find the API key shown in the AgentX account UI and copy it. Keep the key secure and rotate it in AgentX if you think it has been exposed.
Paste the key into MindCloud
Return to MindCloud and paste the copied value into the API Key field for this 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.
