+# API Integration Tests
+
+This directory contains integration tests for the Attune API service.
+
+## Test Files
+
+- `webhook_api_tests.rs` - Basic webhook management and receiver endpoint tests (8 tests)
+- `webhook_security_tests.rs` - Comprehensive webhook security feature tests (17 tests)
+
+## Prerequisites
+
+Before running tests, ensure:
+
+1. **PostgreSQL is running** on `localhost:5432` (or set `DATABASE_URL`)
+2. **Database migrations are applied**: `sqlx migrate run`
+3. **Test user exists** (username: `test_user`, password: `test_password`)
+
+### Quick Setup
+
+```bash
+# Set database URL
+export DATABASE_URL="postgresql://postgres:postgres@localhost:5432/attune"
+
+# Run migrations
+sqlx migrate run
+
+# Create test user (run from psql or create via API)
+# The test user is created automatically when you run the API for the first time
+# Or create manually:
+psql $DATABASE_URL -c "
+INSERT INTO attune.identity (username, email, password_hash, enabled)
+VALUES ('test_user', 'test@example.com', 
+  crypt('test_password', gen_salt('bf')), true)
+ON CONFLICT (username) DO NOTHING;
+"
+```
+
+## Running Tests
+
+All tests are marked with `#[ignore]` because they require a database connection.
+
+### Run all API integration tests
+```bash
+cargo test -p attune-api --test '*' -- --ignored
+```
+
+### Run webhook API tests only
+```bash
+cargo test -p attune-api --test webhook_api_tests -- --ignored
+```
+
+### Run webhook security tests only
+```bash
+cargo test -p attune-api --test webhook_security_tests -- --ignored
+```
+
+### Run a specific test
+```bash
+cargo test -p attune-api --test webhook_security_tests test_webhook_hmac_sha256_valid -- --ignored --nocapture
+```
+
+### Run tests with output
+```bash
+cargo test -p attune-api --test webhook_security_tests -- --ignored --nocapture

+## Troubleshooting
+
+### "Failed to connect to database"
+- Ensure PostgreSQL is running: `pg_isready -h localhost -p 5432`
+- Check `DATABASE_URL` is set correctly
+- Test connection: `psql $DATABASE_URL -c "SELECT 1"`
+
+### "Trigger not found" or table errors
+- Run migrations: `sqlx migrate run`
+- Check schema exists: `psql $DATABASE_URL -c "\dn"`
+
+### "Authentication required" errors
+- Ensure test user exists with correct credentials
+- Check `JWT_SECRET` environment variable is set
+
+### Tests timeout
+- Increase timeout with: `cargo test -- --ignored --test-threads=1`
+- Check database performance
+- Reduce concurrent test execution
+
+### Rate limit tests fail
+- Clear webhook event logs between runs
+- Ensure tests run in isolation: `cargo test -- --ignored --test-threads=1`

+# SSE Integration Tests
+
+This directory contains integration tests for the Server-Sent Events (SSE) execution streaming functionality.
+
+## Quick Start
+
+```bash
+# Run CI-friendly tests (no server required)
+cargo test -p attune-api --test sse_execution_stream_tests
+
+# Expected output:
+# test result: ok. 2 passed; 0 failed; 3 ignored
+```
+
+## Overview
+
+The SSE tests verify the complete real-time update pipeline:
+1. PostgreSQL NOTIFY triggers fire on execution changes
+2. API service listener receives notifications via LISTEN
+3. Notifications are broadcast to SSE clients
+4. Web UI receives real-time updates
+
+## Test Categories
+
+### 1. Database-Level Tests (No Server Required) ✅ CI-Friendly
+
+These tests run automatically and do NOT require the API server:
+
+```bash
+# Run all non-ignored tests (CI/CD safe)
+cargo test -p attune-api --test sse_execution_stream_tests
+
+# Or specifically test PostgreSQL NOTIFY
+cargo test -p attune-api test_postgresql_notify_trigger_fires -- --nocapture
+```
+
+**What they test:**
+- ✅ PostgreSQL trigger fires on execution INSERT/UPDATE
+- ✅ Notification payload structure is correct
+- ✅ LISTEN/NOTIFY mechanism works
+- ✅ Database-level integration is working
+
+**Status**: These tests pass automatically in CI/CD
+
+### 2. End-to-End SSE Tests (Server Required) 🚧 Manual Testing
+
+These tests are **marked as `#[ignore]`** and require a running API service.
+They are not run by default in CI/CD.
+
+```bash
+# Terminal 1: Start API service
+cargo run -p attune-api -- -c config.test.yaml
+
+# Terminal 2: Run ignored SSE tests
+cargo test -p attune-api --test sse_execution_stream_tests -- --ignored --nocapture --test-threads=1
+
+# Or run a specific test
+cargo test -p attune-api test_sse_stream_receives_execution_updates -- --ignored --nocapture
+```
+
+**What they test:**
+- 🔍 SSE endpoint receives notifications from PostgreSQL listener
+- 🔍 Filtering by execution_id works correctly
+- 🔍 Authentication is enforced
+- 🔍 Multiple concurrent SSE connections work
+- 🔍 Real-time updates are delivered instantly
+
+**Status**: Manual verification only (marked `#[ignore]`)
+
+## Test Files
+
+- `sse_execution_stream_tests.rs` - Main SSE integration tests (539 lines)
+- 5 comprehensive test cases covering the full SSE pipeline
+
+## Test Structure
+
+### Database Setup
+Each test:
+1. Creates a clean test database state
+2. Sets up test pack and action
+3. Creates test executions
+
+### SSE Connection
+Tests use `eventsource-client` crate to:
+1. Connect to `/api/v1/executions/stream` endpoint
+2. Authenticate with JWT token
+3. Subscribe to execution updates
+4. Verify received events
+
+### Assertions
+Tests verify:
+- Correct event structure
+- Proper filtering behavior
+- Authentication requirements
+- Real-time delivery (no polling delay)
+
+## Running All Tests
+
+```bash
+# Terminal 1: Start API service
+cargo run -p attune-api -- -c config.test.yaml
+
+# Terminal 2: Run all SSE tests
+cargo test -p attune-api --test sse_execution_stream_tests -- --test-threads=1 --nocapture
+
+# Or run specific test
+cargo test -p attune-api test_sse_stream_receives_execution_updates -- --nocapture
+```
+
+## Expected Output
+
+### Default Test Run (CI/CD)
+
+```
+running 5 tests
+test test_postgresql_notify_trigger_fires ... ok
+test test_sse_stream_receives_execution_updates ... ignored
+test test_sse_stream_filters_by_execution_id ... ignored
+test test_sse_stream_all_executions ... ignored
+test test_sse_stream_requires_authentication ... ok
+
+test result: ok. 2 passed; 0 failed; 3 ignored
+```
+
+### Full Test Run (With Server Running)
+
+```
+running 5 tests
+test test_postgresql_notify_trigger_fires ... ok
+test test_sse_stream_receives_execution_updates ... ok
+test test_sse_stream_filters_by_execution_id ... ok
+test test_sse_stream_requires_authentication ... ok
+test test_sse_stream_all_executions ... ok
+
+test result: ok. 5 passed; 0 failed; 0 ignored
+```
+
+### PostgreSQL Notification Example
+
+```json
+{
+  "entity_type": "execution",
+  "entity_id": 123,
+  "timestamp": "2026-01-19T05:02:14.188288+00:00",
+  "data": {
+    "id": 123,
+    "status": "running",
+    "action_id": 42,
+    "action_ref": "test_sse_pack.test_action",
+    "result": null,
+    "created": "2026-01-19T05:02:13.982769+00:00",
+    "updated": "2026-01-19T05:02:14.188288+00:00"
+  }
+}
+```
+
+## Troubleshooting
+
+### Connection Refused Error
+
+```
+error trying to connect: tcp connect error: Connection refused
+```
+
+**Solution**: Make sure the API service is running on port 8080:
+```bash
+cargo run -p attune-api -- -c config.test.yaml
+```
+
+### Test Database Not Found
+
+**Solution**: Create the test database:
+```bash
+createdb attune_test
+sqlx migrate run --database-url postgresql://postgres:postgres@localhost:5432/attune_test
+```
+
+### Missing Migration
+
+**Solution**: Apply the execution notify trigger migration:
+```bash
+psql postgresql://postgres:postgres@localhost:5432/attune_test < migrations/20260119000001_add_execution_notify_trigger.sql
+```
+
+### Tests Hang
+
+**Cause**: Tests are waiting for SSE events that never arrive
+
+**Debug steps:**
+1. Check API service logs for PostgreSQL listener errors
+2. Verify trigger exists: `\d+ attune.execution` in psql
+3. Manually update execution and check notifications:
+   ```sql
+   UPDATE attune.execution SET status = 'running' WHERE id = 1;
+   LISTEN attune_notifications;
+   ```
+
+## CI/CD Integration
+
+### Recommended Approach (Default)
+
+Run only the database-level tests in CI/CD:
+
+```bash
+# CI-friendly tests (no server required) ✅
+cargo test -p attune-api --test sse_execution_stream_tests
+```
+
+This will:
+- ✅ Run `test_postgresql_notify_trigger_fires` (database trigger verification)
+- ✅ Run `test_sse_stream_requires_authentication` (auth logic verification)
+- ⏭️ Skip 3 tests marked `#[ignore]` (require running server)
+
+### Full Testing (Optional)
+
+For complete end-to-end verification in CI/CD:
+
+```bash
+# Start API in background
+cargo run -p attune-api -- -c config.test.yaml &
+API_PID=$!
+
+# Wait for server to start
+sleep 3
+
+# Run ALL tests including ignored ones
+cargo test -p attune-api --test sse_execution_stream_tests -- --ignored --test-threads=1
+
+# Cleanup
+kill $API_PID
+```
+
+**Note**: Full testing adds complexity and time. The database-level tests provide
+sufficient coverage for the notification pipeline. The ignored tests are for
+manual verification during development.
