​
Introduction

If the tool you want to integrate isn’t in Yuko’s standard connector catalogue, you can build a custom integration using:
  • Custom OAuth Connector — for tools with OAuth 2.0 endpoints.
  • Custom REST API Connector — for tools with API-key authentication.
  • Webhooks + REST API — for fully custom flows.

​
When to use

  • The tool you want isn’t in the catalogue.
  • You’re building an internal tool that consumes Yuko data.
  • You’re integrating Yuko with a partner that supports OAuth 2.0 or REST APIs.

​
Prerequisites

You have OAuth credentials or API keys from the target tool.
You have a developer who can configure the connector mapping.

​
Setup

1

Open Custom Apps

Go to Apps → Yuko Loyalty → Integrations → Custom Apps.
2

Pick the connector type

Choose OAuth or API key based on what your target tool supports.
3

Configure endpoints and credentials

Enter the OAuth callback URLs / API key + base URL.
4

Map events to endpoints

Pick which Yuko events should hit which endpoint on the target tool.
5

Save and test

Yuko sends a test request to verify the connection.

​
Best practices

Use Webhooks + your own integration code for the most flexible custom flows. Custom Apps is for low-code mappings; webhooks are for full control.
Start in a development store. Custom integrations are easy to misconfigure on production.

​
