Short.io API Authentication

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

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

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

Connect Short.io API Key

You need a Short.io account with permission to the domain or team you want MindCloud to access.

  1. Open the Short.io API key page

    Sign in to Short.io and open the API keys page from the dashboard settings.

  2. Create a secret API key

    Select Create API key, choose the domain or team scope you want MindCloud to access, and keep Public key turned off so Short.io generates a Secret Key.

  3. Copy the Secret Key

    Copy the Secret Key and store it securely. You can also note the Domain ID if you plan to run domain-scoped actions.

  4. Paste the key into MindCloud

    In the MindCloud connection form, paste the Secret Key into the API Key field and save the 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.
