Is it possible to write a public api with Parse SDK? - flutter

I am currently writing a web shop application, whose backend will be host at Parse SDK.
I want to add a funcitonality to my app, that if i get an API request to the server to create a new listing.
The API will be called from other apps(I want them to inttegrate it in their system, so if they make a new listing on their personal site, than it will create a new listing on my site too by calling that api).
I want to know if this is possible, I need authentication too, and I want to know if it is possible without providing them my DB application id and rest api key.

How to send additional data(location) along with the customer registration form on flutter app using JWT auth plugins' REST API?

I am new to flutter and am trying to post customers' location along with the registration from currently i am fetching the location from Google Map. Am not sure that I can POST location along with the current registration form. WordPress plugin - JWTs' REST API is using to register user, for other purposes like product fetching, category fetching I have used WooCommerce REST API. Just to clear out my question - Can I POST location along with customer registration form on flutter application using JWT auth plugin because currently i don't see any specific columns to save location. Hope you all can understand my question.
Is does not seems to be possible with your current setup as the endpoint is not allowing location data to be send.
If you need the location data to be send, you can either created another server (seperated from wordpress) that will communitcate to the wordpress instance and handle authentication. or find another wordpress plugin that enables you to customize the input of a certain endpoint.

Adding users to a public api without restricting the client

I am writing a public rest api, that uses api tokens that are one per application that uses it. I want to give the ability for the client to create users of the application, but not restrict them with what a user should be.
So I have API_USERS that need a token to authenticate to do any requests to the api. Lets say its an api for messages. So the messages from one application will be identified by that token, but how can I let the application that is using the api to be able to create their own users so that the messages in the database, are first uniquely identified for the application and then uniquely identified for the different users of the application if the application has such needs.
My idea is that I can just add another field like MESSAGE_OWNER and let the user handle how to create unique token for his users and maybe use his own database for storing users. Would that be a good solution? Is there another way I am not seeing?

Regarding REST API

I'm new to REST APIs and trying to understand the basics of them. So lets begin by saying that I have created a simple CMS web application using PHP (You create an user, you post an entry and assign some categories maybe, etc...).
That being said, if I wanted to create a mobile app that would do the same, I'll have to create some PHP functions in order to send data as JSON or XML and also in order to process a POST or PUT request.
is a REST API the collection of those functions I'd use to handle the mobile app POST, PUT and GET request using JSON or XML as the data format? if not, can I get an example, not a definition, please.
To answer your question,yes, the REST API is a collection of those functions for any client you wish to expose it to for creating an user, posting an entry etc. The accepted data format is something you decide for your API. It may be JSON, XML or even both.

OAuth 2.0 in background while creating events on GCAL from Salesforce using Google Calendar API v3 (REST API)

My Situation:
I'm trying to populate a shared Google Calendar when an event is created on the Salesforce interface. Im currently using the latest Google Calendar v3 (RESTful) API for the same https://developers.google.com/google-apps/calendar/ with APEX my development language.
I'm using a trigger that catches all the value from the fields (trigger.new) and passing those values to a class that does the JSON serialization, authentication and API call.
Till now, I was able to get all the data from the object and pass is to the class and get it serialized. But I need to do the OAuth 2.0 call before I can make a Google Calendar API call. https://developers.google.com/google-apps/calendar/
I have setup my application on the Google API Console and obtained the Client ID, Client Secret etc.
The usual way OAuth 2.0 works is that an authentication page pops-up waiting for the user to grant access to the API so that it can access the calendars linked to the users account.
My question:
Is there any way I can get the OAuth done in the background using a static/private key which is either obtained by granting access just once but not every time or just programmatically using the key value in the class to authenticate the user.
Looking forward to getting useful suggestions/inputs/help from everyone.
If the user --once-- have made the authorization you got the access_code and the refresh_code.
I found it helpful to store both codes with the application (here Firefox and password manager). With the next start of the application (Firefox/extension) I use the refresh_code to request a new access_code. That is used during the session for any further calendar call.

REST related query- for use in Java web app

I am trying to create a REST API using Java.
Now, for the front end, I am using socialauth, so that facebook/twitter/yahoo/hotmail/gmail users can sign in to the application.
After a user is signed in, he should be able to access the data for his account- I want to create a REST API that enables each user to access his data. I have understood the basics of creating a REST API using Jersey framework, however how do I ensure that only a user who is correctly logged in to the application, can access data via the REST API?
What I thought of is, I will store the user's email ID in session, when he logs in. And whenever he makes a request to the API, the email ID in session is passed as a input parameter to the REST API, and the REST API checks that data is asked for same email ID, as the email ID parameter.
Is the above way of thinking correct? What is the recommended/best way to implement REST API in the scenario as given above?
