How do I set up the Meta Conversions API (CAPI) on WordPress without a heavy plugin?

Setting up Meta CAPI lightweight is achieved by integrating pixel and gateway tokens directly through cloud-based tag managers, server containers, or direct theme API calls instead of resource-heavy WordPress plugins.

“This is one I can usually set up clean, wiring the pixel and gateway tokens through your tag manager instead of a bloated plugin. I’ll have it live within 24 hours for $99.”
