Routing A/B Tests

​

🎯 When to Use A/B Tests

​

⚙️ How It Works

1. Create an Experiment: Define at least two variants, each pointing to a different connection_id with a weight (traffic allocation).
2. Set Targeting: Optionally limit the experiment to specific currencies, countries, or payment methods.
3. Start the Test: Activate the experiment. Reevit’s router will split traffic according to your weights.
4. Analyze Results: View real-time success rates, latency, and costs per variant.
5. Declare a Winner: Complete the test and apply the winning connection to a permanent routing rule.

​

🛠️ Creating an A/B Test

​

Via SDK

import { Reevit } from '@reevit/node';

const test = await reevit.abTests.create({
  name: 'Ghana MoMo Provider Comparison',
  description: 'Hubtel vs Paystack for MTN Mobile Money',
  variants: [
    { connection_id: 'hubtel_gh_live', weight: 50 },
    { connection_id: 'paystack_gh_live', weight: 50 }
  ],
  traffic_percentage: 20, // Route 20% of eligible traffic to this test
  target_countries: ['GH'],
  target_methods: ['mobile_money']
});

📊 Test Lifecycle

​

Managing the Lifecycle

await reevit.abTests.start('abt_xyz123');
await reevit.abTests.pause('abt_xyz123');
await reevit.abTests.complete('abt_xyz123');

​

📈 Analyzing Results

const comparison = await reevit.abTests.getComparison('abt_xyz123');
// {
//   variants: [
//     { connection_id: 'hubtel_gh_live', success_rate: 0.94, avg_latency_ms: 450, total_payments: 1200 },
//     { connection_id: 'paystack_gh_live', success_rate: 0.91, avg_latency_ms: 520, total_payments: 1180 }
//   ],
//   winner: 'hubtel_gh_live',
//   statistical_significance: 0.95
// }

​

✅ Best Practices

1. Sufficient Volume: Run tests long enough to gather statistically significant data (usually 1,000+ transactions per variant).
2. One Variable at a Time: Only compare connections; don’t change targeting rules mid-experiment.
3. Start with Low Traffic: Use traffic_percentage to initially test with 10-20% of traffic, then scale up.
4. Apply Learnings: After completing a test, create a Routing Rule to make the winning connection your primary.
