What's the other platform you are trying to integrate with?
Depending on the access it needs, it might require the master API key. Generate this under Settings & Tools > All Settings > API Settings
@Erik Merkley? Thanks for the response. I am integrating it with API2cart.com. Generated the API keys following the steps you mentioned but still getting the same error" Invalid API Key".
Kindly note that my store is still in trial period..does that matters?
I'm pretty sure the API still works on a trial store. You might be better off contacting api2cart.com since the error is coming from their system.
