Question

i want to create an api for my sites so that i allow other web developers to integrete my api for their user login and signup ….. how can i do that…

Answer 1

This is an extremely broad question, so here’s a broad answer: You make a page that takes arguments and outputs the answer in an easily-parsed format (JSON, XML, etc.)

For example: http://example.com/api?action=list_users could return:

<user>
    <userid>1</userid>
    <username>foo</username>
</user>
