SendSafely API Authentication

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

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

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

Connect SendSafely with an API key and API secret

You need a SendSafely Enterprise account with API access. The API secret is shown only once when you generate it, so keep it open until you finish copying both values.

  1. Open your API key settings

    While signed in to SendSafely, open the account menu in the top-right corner, choose Edit Profile, then open the API Keys area.

    Account Menu → Edit Profile → API Keys

  2. Generate a new API key

    Create a new key for MindCloud and give it a clear label such as MindCloud or Cirra.

  3. Copy both values into MindCloud

    Paste the API key into the default API Key field and paste the matching API secret into the API Secret field for this connection.

  4. Save and test the connection

    Save the connection. MindCloud will verify the credentials with SendSafely before you use actions.

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.
