Kiwify API Authentication

How to authenticate Kiwify API requests: one Bearer API key plus a connectionId. MindCloud runs the OAuth flow and refreshes Kiwify tokens for you.

Every Kiwify API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your Kiwify 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 Kiwify connection in Connections. Kiwify uses OAuth. When you create the connection, you are redirected to sign in to Kiwify and approve access — MindCloud stores the resulting tokens and refreshes them automatically, so your integration never has to.
  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 Kiwify account that should run the action. MindCloud stores and refreshes the Kiwify 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 Payouts with an Kiwify connection looks like this:

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

Connect your Kiwify account

Have your Kiwify client_id, client_secret, and account_id ready. MindCloud will exchange the client credentials for an access token automatically.

  1. Paste your Client ID

    Enter the Kiwify client_id issued for your integration.

  2. Paste your Client Secret

    Enter the matching Kiwify client_secret.

  3. Paste your Account ID

    Enter your Kiwify account_id. MindCloud sends this value in the x-kiwify-account-id header on every API request.

  4. Click Connect

    MindCloud calls https://public-api.kiwify.com/v1/oauth/token with Content-Type application/x-www-form-urlencoded and exchanges your client credentials for a bearer token automatically.

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.
