Checkout Page API Authentication

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

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

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

Connect Checkout Page with an API key

You need a Checkout Page seller account and permission to generate API keys in the seller dashboard.

Sign in to your Checkout Page seller dashboard
Open Checkout Page and log in with the seller account you want MindCloud to use.
Open Settings and generate an API key
Go to Settings > API Keys, create a new API key, and copy it immediately because Checkout Page will not show the full key again.
Paste the key into the MindCloud connection form
In the Checkout Page connection form, paste the copied value into the API Key field. MindCloud sends it as a Bearer token in the Authorization header.
Save the connection and test it
Save the connection. MindCloud can then verify the key against Checkout Page read actions like listing checkout pages or customers.

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.
