I do API calls all day long ;)
Seriously, I don't mind reading docs, implementing libraries, and getting this perfected for you. I even have experience with Zapier already. My profile on here does not reflect a lot of my work, but you can see more of my work/skills on linkedin [login to view URL] I don't have any PHP work highlighted in my profile, but I have done PHP in the past, just moved to JS full-stack technologies. Feel free to ask any questions, and thank you for your consideration,
