Integration Options: WebAssembly, APIs, SDKs Across Platforms

I’ve been thinking a lot about cross-platform integration lately, especially when it comes to using something like WebAssembly versus traditional APIs or SDKs. I know each option has its own strengths, but it sometimes feels overwhelming to decide which direction to take. For example, I’ve seen people praising WebAssembly for speed and portability, but I’m not sure how it compares in real-world usage when stacked against a well-designed API or a native SDK. Has anyone here worked on a project where they had to make that choice? I’d love to hear about the trade-offs you faced and what actually worked better in practice.
