Forminit API Authentication

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

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

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

Connect Forminit with an API key

You need access to a protected Forminit form and permission to create API tokens in your Forminit account.

Open API Tokens in Forminit
Sign in to your Forminit dashboard and go to Account > API Tokens.
Create a token
Click Create Token and generate a new API key for the Forminit workspace or form you want to use.
Copy the API key
Copy the token immediately and keep it secure. Forminit uses this value in the X-API-KEY request header for protected forms.
Paste the token into MindCloud
Use the copied token as the API Key value when creating or editing the Forminit connection 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.
