Replace http://ec2-13-234-59-145.ap-south-1.compute.amazonaws.com with http://localhost:3000 for development

1. SignUp

curl --location --request POST 'http://ec2-13-234-59-145.ap-south-1.compute.amazonaws.com/user/signup/' --header 'Content-Type: application/json' --data-raw '{ "email":"[e-mail]", "password":"something" }'

2. Login

curl --location --request POST 'http://ec2-13-234-59-145.ap-south-1.compute.amazonaws.com/user/login' --header 'Content-Type: application/json' --data-raw '{ "email":"[e-mail]", "password":"something" }'

use this token to send in header to get current/next integer and reset integer.

3. Get current Integer(by default '0' for all users)

curl 'http://ec2-13-234-59-145.ap-south-1.compute.amazonaws.com/v1/current --header 'Authorization: Bearer XXXXX'

5. Reset integer to desired value(two ways)

With content type: Content-Type: application/x-www-form-urlencoded. (here 10 is the desired value)

curl --location --request PUT 'http://ec2-13-234-59-145.ap-south-1.compute.amazonaws.com/v1/current' --header 'Authorization: Bearer XXXXX' --data 'current=10'

Or by passing it as a parameter. (here 10 is the desired value)

curl 'http://ec2-13-234-59-145.ap-south-1.compute.amazonaws.com/v1/reset/10' --header 'Authorization: Bearer XXXXX'
