Overview

The GBG GO API allows you to trigger customer journeys programmatically, track their progress, and submit customer data as needed. If you’re building an integration with the GBG GO API, you’ll need to follow a series of API calls to execute a journey successfully. Each step involves retrieving information, handling customer input, and progressing the journey toward completion. This page gives you a high-level view of the journey execution process and what to prepare before you start.

​

Before you begin

Make sure you have the following in place before using the API:

• A published customer journey: A business user must first design and publish the journey in the GBG GO platform. If you’re unsure, check with your team to confirm the journey is ready.
• API access and credentials: You need an API client with a Client ID and Client secret. You create API clients yourself in the Account management portal. See Manage API clients to create one, and the next step, Authenticate, to learn how to use them.
• Understanding of your journey’s tasks: Customer journeys may include document upload, ID checks, or biometric validation. Confirm which steps apply to your specific journey before integrating.

​

Execution flow

A complete customer journey execution consists of six main steps:

1. Authenticate
   Get an access token to authorize API requests.
2. Start a journey
   Trigger a journey instance using the published journey’s resource ID.
3. Retrieve tasks
   Fetch assigned tasks that need to be completed in the journey.
4. Manage schemas
   Retrieve schemas to understand the structure of required data for each task.
5. Submit task data
   Submit data to complete the journey’s tasks.
6. Fetch journey state
   Check the journey’s current progress or completion status.
