Split CSV API Authentication

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

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

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

Create a Split CSV personal API token

You need a Split CSV paid plan or subscription, because the Core API is only available on paid plans.

Open the Split CSV API settings
Sign in to your Split CSV account and open the API tab in Account Settings.
Account Settings → API
Create a new personal API token
Click New Personal API Token, enter a label such as MindCloud Sandbox, and save the token.
Copy the token into MindCloud
Click Copy for the new token, then paste that value into the MindCloud 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.
