I need to create a public API for my application that can receive a single POST request. More specifically, I need to give users the ability to post data to my database -- the user would be another dev shop and they would be posting a LOT of data, so I can't ask them to log into my site and start filling out forms. I realize POST data is typically consumed via the body, not query params (this is GET).
However, I know a lot of public API's out there do this (e.g. https://developer.flightstats.com/api-docs/alerts/v1. If you look at this site and create a 'flight rule', they're saving your call and returning JSON when your parameters return true). What is best practice for this?
I'm currently using Express w/ Sequelize, and PostgresQL.
Question: Is there a way to send a POST request via URI parameters, and more importantly, is there a safe way to do this? And, if there isn't, what is the best way for a user to post data to my database without filling out a form?
