Designing REST API for push-notification

[GarlicB]

I referenced kakao developers.

Default Setting
Host: https://api.absolute.com/v1.0
Authorization: FCM Server Key
Data Format : application/json

We use web-pushlib, and the push server key is fcm (firebase clouding message).

Detail
2-1. Registration
URL: /push/register
Method: POST
Params (all string type)
Endpoint: The id to receive the push.
p256dh: The public key that encrypts the payload between client and server.
auth: The authorization code.

On the client side, the user sends his own token (endpoint, p256dh, auth)
generated from the subscription to the server and stores it in database.

2-2. Unregistration
POST /push/unregister
Method: POST
Params:endpoint,p256dh,auth (same 2-1)
Response: 200 OK 'deleted tokens' <-log msg (example)

Delete the push token for a specific user.

2-3. Show tokens
URL: /push/tokens
Method: GET
Params: querystring 'auth'
auth: user's auth code(default value is null)

If the value of the params is 'null', the entire token list is displayed. (/push/tokens)
Or if you enter a specific auth value, it prints only the corresponding tokens.(/push/tokens?auth='***')

2-4. Send payload to user
URL: /push/send
Method: POST
Params: for_fcm
"for_fcm":{
"comment": "yay, it works",
"delay_while_idle":false,
"time_to_live":17200,
"priority":"high"
}

@romandev. Sorry for being late. I have redesigned it with more information.

@GarlicB Thank you for this.
But you missed some parameter information. Please add the info in more details.
Also, I'm not sure if we need /push/event API in server side.
