3 months in and the hardest part wasn't the code, it was Meta and Google approving me

Been building a SaaS that touches Instagram, WhatsApp, and Google Business Profile for small businesses. Honestly thought the engineering would be the hard part. Turns out getting approved to actually use these platforms took just as long.

Meta rejected my app review once because my screen recording didn't match exactly what I was requesting access for, small mismatch but enough to bounce the whole submission. Google's Business Profile API approval was its own headache too, barely any real documentation, I ended up piecing things together from old forum posts.

Biggest mistake I made: kept building out "final" features while waiting on approval, assuming I'd need to redo half of it anyway once I heard back. Should've just built tight to what I was requesting and iterated after.

Anyone else gone through this with Meta or Google APIs? Curious how close your recordings had to match before they'd approve you.
