Formilla API Authentication

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

Every Formilla API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your Formilla 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 Formilla connection in Connections. Formilla uses an API key. You generate the key in your Formilla 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 Formilla account that should run the action. MindCloud stores and refreshes the Formilla 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 Create or Update Contact (Email Required) with an Formilla connection looks like this:

curl --request POST \
  --url "https://connect.mindcloud.co/v2/universal/apps/formilla/actions/upsert-contact-by-email/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 Formilla account to run the action against. Missing or invalid Authorization returns 401, and a missing or mismatched connectionId returns 400.

Get your Formilla REST API token

You must be signed in to Formilla as the Account Owner.

Open Formilla settings
Sign in to Formilla, then open Settings from the left menu.
Open the Security page
On the Settings page, choose Security from the left-side sub-menu.
Enable the REST API
Under the Formilla REST API section, switch REST API Enabled to Yes.
Copy the Secure Token
Copy the Secure Token that Formilla generated for the REST API.
Paste the token into MindCloud
Use that Secure Token as the API Key value when creating or editing your MindCloud Formilla 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.
