casehub-connectors

Lightweight outbound message connectors for the CaseHub platform.

Provides a unified Connector SPI with built-in implementations for:

Connector	Module	ID	Auth
Slack (Incoming Webhooks)	casehub-connectors	slack	Webhook URL (no credentials)
Microsoft Teams (Adaptive Cards)	casehub-connectors	teams	Webhook URL (no credentials)
Twilio SMS	casehub-connectors	twilio-sms	Account SID + Auth Token
WhatsApp Business (Meta)	casehub-connectors	whatsapp	API Token + Phone Number ID
Email (quarkus-mailer)	casehub-connectors-email	email	SMTP config

Why this exists

• No Camel: Camel Quarkus has Slack and Twilio components but the full Camel stack is a heavy dependency for outbound webhooks.
• No vendor SDK: Pure java.net.http.HttpClient — zero extra dependencies for HTTP-based connectors.
• CDI SPI: Custom connectors implement Connector as @ApplicationScoped CDI beans and are discovered automatically.

Usage

<!-- HTTP-based connectors: Slack, Teams, Twilio SMS, WhatsApp -->

Configuration

# Twilio SMS (only needed if you use the twilio-sms connector)
casehub.connectors.twilio.account-sid=ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
casehub.connectors.twilio.auth-token=your_auth_token
casehub.connectors.twilio.from=+14155552671

# WhatsApp Business (only needed if you use the whatsapp connector)
casehub.connectors.whatsapp.api-token=EAAxxxx...
casehub.connectors.whatsapp.phone-number-id=12345678901234

# Slack and Teams: no config needed — webhook URL goes in ConnectorMessage.destination()

Sending a message

@Inject
@Any
Instance<Connector> connectors;

// Find and use a specific connector
connectors.stream()
    .filter(c -> "slack".equals(c.id()))
    .findFirst()
    .ifPresent(c -> c.send(new ConnectorMessage(
        "https://hooks.slack.com/services/T.../B.../...",  // destination
        "WorkItem Assigned",                                // title
        "Loan application #1234 has been assigned to alice" // body
    )));

Custom connectors

@ApplicationScoped
public class PagerDutyConnector implements Connector {
    @Override public String id() { return "pagerduty"; }
    @Override public void send(ConnectorMessage message) { /* ... */ }
}
