I have a web application made in .NET and I need to connect it with several Salesforce accounts to access data in Salesforce with OAuth2.0. How can I do it?

I have seen this document: https://help.salesforce.com/help/doc/en/remoteaccess_oauth_web_server_flow.htm

and I need a client_id (Consumer key from the remote access application definition) to obtain Access Authorization. But as I want is to connect my application with salesforce organizations of my clients, on which I have no access credentials, how do I get the customer_id?

On the other hand I have seen applications that connect to salesforce redirected to this page to request permission:


But I don't know what is the "source" param.

One of the applications I've seen that connects to salesforce and uses the authorization process is "zapier.com".

I made a zapier connecting to my development org and within "Connected Apps OAuth Usage", in mi org, Setup --> Administration Setup --> Manage Apps, I can see the following:


Connected App: Zapier User Count: 1

From this moment zapier can access the data from my salesforce organization via API.

This is exactly what I want to achieve.

I'm a little lost. Can anyone help me?

You don't need a Connected App ID in the customer org - just in your own DE org (see this answer for a little more detail). So, create a Connected App in your DE org (but see this note!), implement your app to use the web server flow (see this article for much more detail), and users will be able to use your app. You can easily test by creating a second DE org and trying to use your app from there.
