Exchange Trigger

Exchange Trigger

The exchange trigger functionality is available for PDC v1.10.0 and above.

This feature enables a PTX Catalogue to trigger data exchanges in behalf of the participant, by offering the participant a dashboard with available exchanges and launching them with a single click of a button.

It is an optional feature to facilitate some use cases.

Overview

The idea of this feature is to take away as much integration work as possible from dataspace participants by enabling the PTX Catalogue, which has the information about participants, offers and contracts to offer an "Exchange Trigger" dashboard feature where participants can trigger an exchange with a simple click of a button.

This essentially removes having to:

• Retrieve your different signed contracts
• Configure the exchange payloads to target specific offers in the contract
• Implementing a search logic to identify relevant exchanges based on all that you have available
• Triggering service chains without worrying about setting up the service chain payloads

Configuration

To configure this feature, there are a couple requirements:

1. Your used PTX Catalogue should have a feature to generate an exchange trigger API Key.
2. You need to generate this API Key
3. You need to configure this API Key in your PDC's .env file using the following configuration:

EXCHANGE_TRIGGER_API_KEY=your_generated_api_key_here

This API Key is used to secure the authorization from the catalogue to your PDC when triggering data exchanges.

Once set, you will need to restart your connector for the changes to take effect.
