DeepSeek API Authentication

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

Every DeepSeek API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your DeepSeek 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

  1. Create a MindCloud account at app.mindcloud.co if you do not already have one.
  2. Generate a MindCloud API Key in API Keys. This is the Bearer token you send on every request. Keep it on your server.
  3. Create a DeepSeek connection in Connections. DeepSeek uses an API key. You generate the key in your DeepSeek account, then paste it in when you create the connection — MindCloud stores it securely and never returns it in a response.
  4. 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 DeepSeek account that should run the action. MindCloud stores and refreshes the DeepSeek 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 Models with an DeepSeek connection looks like this:

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

Create a DeepSeek API key

DeepSeek uses the same account for the Open Platform API and the DeepSeek web service. Keep the API key secret and never expose it in browser or other client-side code.

  1. Sign in to your DeepSeek account

    Open the DeepSeek Open Platform with the account you want MindCloud to use for API access.

  2. Create an API key for the account

    Create a new API key through your DeepSeek account and store it somewhere secure as soon as it is shown.

  3. Paste the key into MindCloud

    Return to the MindCloud DeepSeek connection form and paste the copied API key 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.
