Conversion API Setup with Retreaver

I'm currently in need of professional assistance to help me set up a conversion API for my meta account with a call tracking platform called Retreaver.

Key Tasks include:

- Initial configuration of the Conversion API
- Testing and verifying data passback
- Configuring custom parameters for advanced tracking

As a non-tech-savvy individual, I'm not certain about the platform or website for the setup, and I would need guidance on this part as well. The ideal freelancer for this project would be knowledgeable in API setup, advanced tracking configuration, and proficient with platforms like Retreaver. Further, strong skills in explaining technical concepts in a simple to understand manner would be highly beneficial.
