REST API

Introduction

As of Easy!Appointments v1.2 a flexible REST API is integrated within the project that will make it possible to handle all the information of your installations from external clients. The API is using JSON as it's transaction format and features many great practices in order to make the resources easily consumable.

Making Requests

The new API (v1) supports Basic Authentication which means that you will have to send the "Authorization" header with every request you make. Always use SSL/TLS when making requests to a production installation. That way you can ensure that no passwords will be stolen during the requests. The API expects the username and password of an admin user.

The API follows the REST structure which means that the client can use various HTTP verbs in order to perform various operations to the resources. For example you should use a GET request for fetching resources, a POST for creating new and PUT for updating existing ones in the database. Finally a DELETE request will remove a resource from the system.

GET requests accept some parameter helpers that enable the sort, search, pagination and minification of the responses information. Take a look in the following examples:

Search

Provide the q parameter to perform a search in the resource.

http://ea-installation/index.php/api/v1/appointments?q=keyword

Sort

Sort the results in ascending (+) or descending (-) direction by providing the the respective sign and the property name to be used for sorting.

http://ea-installation/index.php/api/v1/appointments?sort=-id,+book,-hash

You can provide up to three sorting fields which will be applied in the provided order.

Paginate

Paginate the result by providing the page parameter along with the optional length parameter that defaults to 20.

http://ea-installation/index.php/api/v1/appointments?page=1&length=10

Minimize

If you need to get only specific values from each JSON resource provide the fields GET parameter with a list of the required property names.

http://ea-installation/index.php/api/v1/appointments?fields=id,book,hash,notes

Expected Responses

Most of the times the API will return the complete requested data in a JSON string but there are some cases that the responses will contain a simple message like the following:

{
    "code": 404,
    "message": "The requested record was not found!"
}

Such simple messages contain the HTTP code and a message stating a problem or a success to an operation.

Try it out!

At this point you can start experimenting with the API and your intallation. The following section of this document describes the available resources and how they can be used. Before building your API consumer you can use cURL or Postman to try out the API.

Get all the registered appointments:

curl http://ea-installation/index.php/api/v1/appointments --user username:password

Get the data of a customer with ID 34:

curl http://ea-installation/index.php/api/v1/customers/34 --user username:password

Update the name of a category with ID 23:

curl -H 'Content-Type: application/json' -X PUT -d '{"name": "New Name!"}' http://ea-installation/index.php/api/v1/categories/23 --user username:password

Delete the service with ID 15:

curl -X DELETE http://ea-installation/index.php/api/v1/services/15 --user username:password

You can also try the GET requests with your browser by navigating to the respecive URLs.

API Roadmap

Although the current state should be sufficient for working with the application data there are some other features of that will make the consume more flexible and powerfull. These will be added gradually with the future releases of Easy!Appointments.

[ ] Add auto-generated links whenever external resource IDs are provided. [ ] Add pagination header links when the client provides pagination parameters. [ ] Add support for sub-resourcing e.g. /api/v1/customers/:id/appointments must return all the appointments of a specific customer. [ ] Add custom filtering parameters e.g. /api/v1/appointments?book=>2016-07-10 [ ] Improved exception handling.

Feel free to make pull requests if you have the time to develop one of those.

Troubleshooting

Authorization Issues

If your server runs PHP through FastCGI you will the authorization will not work because the Authorization header is not available to the PHP scripts. You can easily fix this by applying the following adjustments depending your server sortware:

Apache

Add the following code snippet to an .htaccess file in the installation root directory if you have mod_rewrite installed and enabled:

RewriteEngine on
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]

[Source]

Add the following code snippet to an .htaccess file in the installation root directory if you have mod_setenvif installed and enabled:

SetEnvIf Authorization .+ HTTP_AUTHORIZATION=$0

[Source]

NGINX

Add the following code snippet to the NGINX .conf file:

fastcgi_param PHP_AUTH_USER $remote_user;
fastcgi_param PHP_AUTH_PW $http_authorization;
