Softr API Authentication

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

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

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

Set up your Softr API key

You need to be the Softr app owner or a workspace collaborator to make API calls. Softr API keys are scoped to one or more workspaces. If you plan to use Softr user-management actions, also have your published app or custom domain ready for the optional Softr Domain field in MindCloud.

Open your Softr API settings
Sign in to Softr, open the Dashboard, then click your profile icon and go to My account > API Settings.
Dashboard → My account → API Settings
Generate or copy your API key
If you do not have a key yet, click Generate API key. Then copy the full key exactly as Softr shows it and keep it confidential.
Paste the key into MindCloud
Return to the MindCloud connection form and paste the copied value into the Softr API key field.
Add your Softr domain when needed
If you plan to use Softr user-management actions, enter your published app domain or custom domain in the optional Softr Domain field.

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.
