I am setting up a zap to automatically post on Instagram with the IG for business app. Everything works fine and all tests passed.. Just the latest step, I get the error: 

Failed to create a media in Instagram for Business The app returned "The request is missing a valid API key."

I don’t know where to add an API key and also from numerous tutorials on this workflow, it didn’t seem I need one. 

Can you help me?

Would you be able to provide the screenshots of how you setup your connection to instagram to create a post? I’m totally new to this and your query is the closest I can find on a potential example on how to set it up.  I’m actually doing a wordpress to instagram post but there are no actual examples of connecting to instagram business, only documentation which I don’t understand as I’m not techy enough!  thank you!
