BuildBetter API Authentication
How to authenticate BuildBetter API requests: one Bearer API key plus a connectionId. MindCloud stores your API key securely — set it once, never resend it.
Every BuildBetter API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your BuildBetter 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 BuildBetter connection in Connections. BuildBetter uses an API key. You generate the key in your BuildBetter 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 BuildBetter account that should run the action. MindCloud stores and refreshes the BuildBetter 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 Recent Calls with an BuildBetter connection looks like this:
curl --request POST \
--url "https://connect.mindcloud.co/v2/universal/apps/buildBetter/actions/list-recent-calls/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 BuildBetter account to run the action against. Missing or invalid Authorization returns 401, and a missing or mismatched connectionId returns 400.
Connect BuildBetter with an API key
You need a BuildBetter account with access to API & MCP settings.
- Open API & MCP Settings
In BuildBetter, open your API & MCP Settings to manage developer access and API keys.
- Generate an organization API key
Create a new API key for your organization and copy it when BuildBetter shows it.
- Use the API key in your connection
Paste the organization API key into the BuildBetter connection when prompted.
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.
