Where do you add the parameters to connect to an external API?

I’m a super beginner with the use of APIs, but I was able to configure an API using Bubble.io to pull in data from an external app called LimbleCMMS. It was simple to configure using Bubble because they had an API Connector that prompted for the OAuth inputs (the client ID, the secret, and the url for the get function, to name a few). Is this possible in Coda, or how else is this accomplished? I would much prefer the data come into a Coda doc than in Bubble, but since I’ve gotten it to work in Bubble, I may focus my energies there. Any advice??
