I have an Express POST route that creates a record. When I test the API, it successfully creates the record populated with all the right info (I checked the table). However, I receive no response from the API (Postman times out, and in the console I get - - ms - -).
In that “missing” part, your API needs to tell the browser that the request to airtable.com is complete and also whether or not the request was successful. In Express.js, that can be done with request.end and request.send; you can learn more about using Express in that project’s documentation:
