CONVERSION API PURCHASE EVENT FACEBOOK

I am looking for a freelancer who is experienced in working with Kartra and familiar with Facebook's Conversion API.

I've already set with Zapier. Zapier said to me that the conversion of the purchase has been sent to Facebook but I can't see it. Why?

Platform: Kartra
- The website is built on the Kartra platform.

Facebook Pixel:
- The Facebook pixel is installed on the website.

Conversion API:
- Although I am not familiar with Facebook's Conversion API, I am willing to learn and would like the freelancer to guide me through the process.

Skills and Experience:
- Experience working with Kartra and integrating Facebook's Conversion API.
- Knowledge of Facebook's Conversion API and its implementation.
- Ability to provide guidance and support in learning and implementing the Conversion API.

If you have the skills and experience required for this project, please submit your proposal.
