VertexFX Bridge LP API Introduction
Posted by Yousef Ibrahim, Last modified by Diana Alkouni on 09 September 2020 10:40 AM

VertexFX Bridge Liquidity Provider (LP) API is a .NET Class Library DLL used for implementing new LP in the VertexFX Bridge application. All what you need is to build your own .NET Class Library project, with Assembly name prefix VFX from project properties. The project should have class name LP inherited from VertexFXBridgeLPAPI.VertexFXLP class over the provided API, then build the DLL after overriding the needed functions, finally copy this DLL (with its dependences) in the LP References folder of the VertexFX Bridge application which is located in "[user appdata]\Roaming\VertexFX Bridge" folder in order to be supported.

After finishing your LP DLL, you may test it using the Tester application included when installing the VertexFX Bridge LP API.

When installing VertexFX Bridge LP API you will have:

  • The Class Library DLL (VertexFXBridgeLP.dll), which you have to add its reference in your own LP Class Library project.
  • The API tester (VertexFX Bridge LP API Tester.exe), which you can use for testing your own DLL. This application has a wizard, if passed, your DLL is eligible and is supported in VertexFX Bridge.
  • Open source .NET sample, of how to build an LP DLL, built over VertexFX Client API.

Apology for the post in date 27 March 2012 01:35 PM. I meant all what you need is the Bridge API and nothing else as the Bridge API is a kit for using the vertex Bridge Rules with another Non-vertex system. there is no need for Vertex Client API, you need the other party's client API in order to integrate it with the VertexFX Bridge API..

However, and in case you need to develop your own bridging application with its own rules and functionality other than the existing rules in the vertex bridge itself, you can use the VertexFX Backoffice API and develop your own Bridge with the other Party's client API but this is a longer cycle where we simplified it by building the Bridge and disclosed its API.

Hello Sam,

Yes, you will need our API for bridging depending on the business category, however, if you work alone, you will need to sign an ISV agreement, check out our ISV Program at

If you need any further information, please let us know
