SmartSuite API Authentication

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

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

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

Connect SmartSuite with an API token

You need access to the SmartSuite workspace you want to connect and permission to open your SmartSuite profile settings.

Copy your Workspace ID
Open your SmartSuite workspace URL and copy the first 8 characters after https://app.smartsuite.com/. SmartSuite documents this value as your Workspace ID.
Help Center → Retrieving your API Key and Workspace Id
Generate or copy your API token
In SmartSuite, open your user profile and generate or copy your API key. SmartSuite notes that the key is user-specific and carries that user's permissions.
Help Center → Generating an API Key
Enter the values in MindCloud
Paste the Workspace ID into the Workspace ID field and paste the API token into the API Key field when creating 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.
