Hi all. I'm new to APIs. I've got my keys and access to a Sandbox, and can now successfully GET information. I'm using Thunder client on VS Code. Now it's time for me to try to POST something. I'm trying to add an Invoice for Services Rendered to Acme Dynamite Co. for $50.00 on 1/9/24. However, because I don't yet know the correct syntax in the Body, I'm getting error 400 Bad Request, and I don't know what part is Bad, so I don't know what to fix. Would it be possible for someone to show me the correct syntax in the Body for this request to be successful?
