Hello, how are you?
I'm a senior web developer and I have rich experience in Facebook Marketing api integration.
I integrated Facebook Marketing api on FinTech project, eCommerce project, POS project's campaign.
I guess you already have source code and I have to work there to integrate api.
What I always trend is high quality.
I will give you perfect result as you want with high satisfaction.
Let us discuss in detail via chat.
Best regards,
Heindrick.
