B2B Wave API Authentication

How to authenticate B2B Wave API requests: one Bearer API key plus a connectionId. MindCloud stores your API key securely — set it once, never resend it.

Every B2B Wave API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your B2B Wave 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

  1. Create a MindCloud account at app.mindcloud.co if you do not already have one.
  2. Generate a MindCloud API Key in API Keys. This is the Bearer token you send on every request. Keep it on your server.
  3. Create a B2B Wave connection in Connections. B2B Wave uses an API key. You generate the key in your B2B Wave account, then paste it in when you create the connection — MindCloud stores it securely and never returns it in a response.
  4. 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 B2B Wave account that should run the action. MindCloud stores and refreshes the B2B Wave 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 Categories with an B2B Wave connection looks like this:

curl --request POST \
  --url "https://connect.mindcloud.co/v2/universal/apps/b2BWave/actions/list-categories/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 B2B Wave account to run the action against. Missing or invalid Authorization returns 401, and a missing or mismatched connectionId returns 400.

Connect B2B Wave

You need the root URL of your B2B Wave store and an active API key with access to the resources you want to use.

  1. Find your store URL

    Use the root URL of your B2B Wave store. If you only have a sign-in URL like https://yourstore.b2bwave.com/users/sign_in, remove /users/sign_in and use https://yourstore.b2bwave.com instead.

  2. Sign in to your B2B Wave adminSign in
  3. Open the API Keys page

    In your admin, go to Settings > API Keys.

    Settings → API Keys

  4. Create or copy an API key

    Create an API key if needed, keep it Active, and give it the scopes your integration needs. The docs list scopes such as All, Order list, Order edit, Product list, Product edit, Customer list, and Customer edit.

  5. Enter the connection values in MindCloud

    Paste your API key into the API Key field and enter your store root URL in the Store URL 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.
