Placid API Authentication

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

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

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

Get your Placid API token

You need access to the Placid project that contains the templates you want to use.

Open the Placid project you want to use
Placid API tokens are project-specific. Choose the project that contains the templates you plan to generate from.
Copy the API token from the project overview
Open the project overview and copy the Placid API token for that project.
Paste the token into the MindCloud connection
Use the copied token as the API key for this Placid connection.
Verify the token against a template in the same project
Run a safe read such as List Templates or Get Template. The token and template UUID must belong to the same Placid project.

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.
