Sifter API Authentication

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

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

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

Connect your Sifter account

You need a Sifter access key and your account subdomain.

  1. Sign in to your Sifter account

    Open your Sifter account in a browser and sign in with the account you want to connect.

  2. Open your profile settings

    Use the top navigation to open My Profile.

  3. Create an access key

    In the right sidebar, open Access Keys. Fill in the Create New Access Key form at the bottom of the page, then click Create Access Key.

  4. Copy the access key value

    Copy the full access key value and keep it available for the MindCloud connection.

  5. Find your account subdomain

    Use only the subdomain part of your Sifter URL. For example, if your account URL is https://acme.sifterapp.com, enter acme in MindCloud.

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.
