Airtable API Authentication

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

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

curl --request GET \
  --url "https://connect.mindcloud.co/v1/universal/airtable/latest/actions/list-bases" \
  --header "Authorization: Bearer $MINDCLOUD_API_KEY" \
  --get \
  --data-urlencode "connectionId=$CONNECTION_ID"

The Authorization: Bearer <your MindCloud API Key> header authenticates you to MindCloud; the connectionId tells MindCloud which Airtable account to run the action against. Missing or invalid Authorization returns 401, and a missing or mismatched connectionId returns 400.

Create an Airtable personal access token

Airtable user API keys no longer work for the Airtable API. For individual API access, Airtable requires a personal access token.

Open Airtable's developer hub
Open Airtable's developer hub, then go to Personal access tokens under the Developers section.
Developer hub → Personal access tokens
Create the token and choose scopes
Click Create token, give the token a name, and add the scopes your Airtable workflows need.
Choose which resources the token can access
Use Add all resources or Add a base to choose which bases or workspaces the token can reach.
Use the new token in MindCloud
Return to MindCloud and paste the Airtable personal access token into the API key field for this 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.
