SignalWire API Authentication

How to authenticate SignalWire API requests: one Bearer API key plus a connectionId. MindCloud stores your SignalWire credentials — no auth headers to build.

Every SignalWire API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your SignalWire 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 SignalWire connection in Connections. SignalWire uses a username and password. You enter them when you create the connection — MindCloud stores them securely so your requests never carry raw credentials.
  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 SignalWire account that should run the action. MindCloud stores and refreshes the SignalWire 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 Fabric Resources with an SignalWire connection looks like this:

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

Connect SignalWire

Use the mindcloud SignalWire space and a SignalWire API token with the scopes required for the endpoints you want to run.

  1. Copy the Project ID

    Open the SignalWire Dashboard for the mindcloud space and copy the Project ID. Enter that value as the Username in MindCloud.

  2. Copy or create an API Token

    Create or copy a SignalWire API token with the scopes needed for the REST endpoints you plan to use. Enter that value as the Password in MindCloud.

  3. Save the connection

    This wrapper is configured for mindcloud.signalwire.com, so requests will go to that space-specific API base 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.
