Migrate from another provider

Migrating your payments should never interrupt revenue collection. This progressive approach lets you switch over smoothly, with the ability to roll back at any time.

Principle: route in parallel

Rather than a "big bang", let the old provider and Wajub coexist, and shift traffic gradually.

Steps

1. Integrate in test

Reproduce your current payment collection flow with Wajub test keys, without touching production.

2. Map your data

3. Route a percentage of traffic

First route a small share (e.g. 10%) to Wajub via a simple application switch, and compare success rates in the Dashboard.

function choosePsp(order) {
// controlled ramp-up
return Math.random() < ROLLOUT_RATIO ? 'wajub' : 'legacy';
}

4. Scale up

Increase the Wajub share as metrics confirm better results. Enable orchestration for automatic fallback — often Wajub alone replaces multiple direct integrations.

5. Decommission the old provider

Once 100% of traffic has been switched and is stable over several settlement cycles, remove the old integration.
