Subscribers API (demo)

This is a demo about how a subscribers API (for a newsletter for instance) could be implemented. This demo allows managing subscribers (Create, Read, Update and Delete) with or without additional fields. each subscriber can have 0 or multiple fields, but these fields and their types should be created by the user (the owner of the newsletter) beforehand, otherwise any non accepted field will be ignored. In addition, this API allows searching/updating/deleting subscribers either by their ID or by their email addresses.

How to install

• Clone this repo: git clone https://github.com/djug/subscribers-api-demo.git
• cd subscribers-api-demo/
• Install the dependencies: composer install
• Create a new database and create/update your .env file accordingly
• run the migrations php artisan migrate
• generate an encryption key php artisan key:generate
• Lunch the built-in PHP webserver php artisan serve
• Visit http://127.0.0.1:8000/ to see the demo homepage

How to get the API Key

• create a new account and login
• you'll get redirected to the dashboard page that contains your API key

• Use this API Key to send the request to the API (next section)

How to test

Create a field

curl -X POST http://127.0.0.1:8000/api/fields/ -d '{"title": "job", "type" : "string"}' -H "Content-Type: application/json" -H "X-MailerLite-ApiKey: yYsZaEJOgm7E0zK9VpbUZV87wokj82o3wJBND1LmhgZI3axsyrIxsiCz3ics"

Result:

{"title":"job","type":"string","updated_at":"2018-04-03 17:16:21","created_at":"2018-04-03 17:16:21","id":1}

Update a field

curl -X PUT http://127.0.0.1:8000/api/fields/1 -d '{"title": "Job Title", "type" : "string"}' -H "Content-Type: application/json" -H "X-MailerLite-ApiKey: yYsZaEJOgm7E0zK9VpbUZV87wokj82o3wJBND1LmhgZI3axsyrIxsiCz3ics"

Result:

{"id":1,"title":"Job Title","type":"string","created_at":"2018-04-03 17:16:21","updated_at":"2018-04-03 17:18:02"}

Create a new subscriber

curl -X POST http://127.0.0.1:8000/api/subscribers -d '{"email":"contact@youghourta.com", "name": "Youghourta", "fields": {"Job Title":"developer", "company": "djugprog"}}' -H "Content-Type: application/json" -H "X-MailerLite-ApiKey: yYsZaEJOgm7E0zK9VpbUZV87wokj82o3wJBND1LmhgZI3axsyrIxsiCz3ics"

Result:

{"email":"contact@youghourta.com","name":"Youghourta","updated_at":"2018-04-03 17:20:03","created_at":"2018-04-03 17:20:0  
3","id":1,"fields":[{"title":"Job Title","value":"developer","type":"STRING"}]}

Notice that the company field was ignored, since it is not an "accepted" field (i.e it wasn't added to the list of accepted fields)

Update an existing subscriber:

curl -X PUT http://127.0.0.1:8000/api/subscribers/1 -d '{"state":"unsubscribed"}' -H "Content-Type: application/json" -H "X-MailerLite-ApiKey: yYsZaEJOgm7E0zK9VpbUZV87wokj82o3wJBND1LmhgZI3axsyrIxsiCz3ics"

we can also use the email address instead of the ID in the previous request

curl -X PUT http://127.0.0.1:8000/api/subscribers/contact@youghourta.com -d '{"state":"unsubscribed"}' -H "Content-Type: application/json" -H "X-MailerLite-ApiKey: yYsZaEJOgm7E0zK9VpbUZV87wokj82o3wJBND1LmhgZI3axsyrIxsiCz3ics"

result:

{"id":1,"email":"contact@youghourta.com","name":"Youghourta","state":"unsubscribed","created_at":"2018-04-03 17:20:03","u  
pdated_at":"2018-04-03 17:25:36","fields":[{"title":"Job Title","value":"developer","type":"STRING"}]}

we can also update the fields:

curl -X PUT http://127.0.0.1:8000/api/subscribers/1 -d '{"fields": {"Job Title":"Back-end Developer"}}' -H "Content-Type: application/json" -H "X-MailerLite-ApiKey: yYsZaEJOgm7E0zK9VpbUZV87wokj82o3wJBND1LmhgZI3axsyrIxsiCz3ics"

result:

{"id":1,"email":"contact@youghourta.com","name":"Youghourta","state":"unsubscribed","created_at":"2018-04-03 17:20:03","u  
pdated_at":"2018-04-03 17:25:36","fields":[{"title":"Job Title","value":"Back-end Developer","type":"STRING"}]}

Test

this project includes some tests that you can run locally. in order to run the tests we need the following steps:

• Create a new testing database (let's name it test_api_db)
• run the migration on it DB_DATABASE=test_api_db php artisan migrate (we are passing the name of the test DB as an environment variable to override temporarily the DB_DATABASE environment variable)
• Update the phpunit.xml we need to add the following lines to the phpunit.xml file between <php> and </php> tags, so we can run tests using our test database:

   <env name="DB_DATABASE" value="mailer_test"/>
      <env name="DB_USERNAME" value="bdd"/>
      <env name="DB_PASSWORD" value="123"/>
      <env name="DB_PERSISTENT" value="false"/>
  

• run vendor/bin/phpunit

To do

• validate / cast the fields before adding them (useful especially for date fields)
• write an SDK and its documentation
