SPINEN's Halo PHP Client

PHP package to interface with Halo Service Solutions. We strongly encourage you to review Halo's API docs to get a feel for what this package can do, as we are just wrapping their API.

We solely use Laravel for our applications, so this package is written with Laravel in mind. We have tried to make it work outside of Laravel. If there is a request from the community to split this package into 2 parts, then we will consider doing that work.

Installation

Install Halo PHP Package via Composer:

$ composer require spinen/halo-php-client

Laravel Setup

You will need to make your User object implement includes the Spinen\Halo\Concerns\HasHalo trait which will allow it to access the Client as an attribute like this: $user->halo

<?php

namespace App;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Spinen\Halo\Concerns\HasHalo;

class User extends Authenticatable
{
    use HasHalo, Notifiable;

    // ...
}

Add the appropriate values to your .env file

Keys

HALO_RESOURCE_SERVER=<API Resource Server>
HALO_TENANT=<Optional Tenant>
HALO_AUTHORIZATION_CODE_CLIENT_ID=<Needed if using Authorization Code>
HALO_CLIENT_CREDENTIALS_CLIENT_ID=<Needed if using Client Credentials>
HALO_CLIENT_CREDENTIALS_CLIENT_SECRET=<Needed if using Client Credentials>

[Optional] Publish config & migration

Config

A configuration file named halo.php can be published to config/ by running...
```
php artisan vendor:publish --tag=halo-config
```
Migration

Migrations files can be published by running...
```
php artisan vendor:publish --tag=halo-migrations
```
You'll need the migration to set the Halo API token on your User model.

Generic PHP Setup

You need to build up an array of configs to pass into the Halo object. You review the halo.php file in the configs directory. All of the properties are documented in the file.

Depending on your needs, you can either work with the Halo client or the Builder

The $builder instance will work exactly like all of the examples below where halo() is a method.

Authentication

Halo has four ways to authenticate when making API calls. With this package we are focusing on the following two: 1) Authorization Code or 2) Client Credentials. The Authorization Code method is used to make API calls to the API as specific users. If you are using Laravel to interact with this package, then the authorization flow is built out for you. If you are not, then review Http\Middleware\Filter to see how we redirect the user to the Halo server to request a code and Http\Controllers\HaloController to see how we convert the code into a token. The flow is protected with PKCE. The Client Credentials method is used to make API calls as a specific user and is useful for background processes.

NOTE: You can use either method or both methods in the same project.

Authorization Code

There is a middleware named Halo that you can apply to any route that verifies that the user has a halo_token, and if the user does not, then it redirects the user to Halo's OAuth page with the client_id where the user selects the team(s) to link with your application. Upon selecting the team(s), the user is redirected to the named route halo.sso.redirect_uri where the system converts the code to a token & saves it to the user. Upon saving the halo_token, the user is redirected to the initial page that was protected by the middleware.

NOTE: You will need to have the auth middleware on the routes as the User is needed to see if there is a halo_token.

NOTE: At this time, there is not a way to remove a token that has been invalidated, so you will need to delete the halo_token on the user to restart the flow.

Client Credentials

When using Client Credentials, you can make API calls without needing any user interface or requiring any user interaction.

Using the Client

The Client is meant to emulate Laravel's models with Eloquent. When working with Halo resources, you can access properties and relationships just like you would in Laravel.

Getting the Client object

When using `Authorization Code`

By running the migration included in this package, your User class will have a halo_token column on it. When you set the user's token, it is encrypted in your database with Laravel's encryption methods. After setting the Halo API token, you can access the Client object through $user->halo.

php artisan tinker
Psy Shell v0.11.14 (PHP 8.2.4 — cli) by Justin Hileman
> $user = App\Models\User::find(1)
= App\Models\User {#4344
    id: 1,
    name: "Jimmy",
    email: "[email protected]",
    email_verified_at: null,
    ...
> $user->halo;
= Spinen\Halo\Api\Client {#4748}

> $user->halo();
= Spinen\Halo\Support\Builder {#4706}

Models

The API responses are cast into models with the properties cast into the types as defined in the Halo API documentation. You can review the models in the src/ folder. There is a property named casts on each model that instructs the Client on how to cast the properties from the API response. If the casts property is empty, then the properties are not defined in the API docs, so an array is returned.

NOTE: The documented properties on the models are likely to get stale as Halo is in active development

> $user->halo()->teams->first()
= Spinen\Halo\Team {#4967
    +exists: true,
    +incrementing: false,
    +parentModel: null,
    +wasRecentlyCreated: false,
    +timestamps: false,
  }

> $user->halo()->teams->first()->toArray()
= [
    "id" => 1,
    "guid" => "<masked>",
    "name" => "1st Line Support",
    "sequence" => 10,
    "forrequests" => true,
    "foropps" => false,
    "forprojects" => false,
    "ticket_count" => 0,
    "department_id" => 3,
    "department_name" => "SPINEN - Support",
    "inactive" => false,
    "override_column_id" => 0,
    "teamphotopath" => "",
    "use" => "team",
  ]

Relationships

Some of the responses have links to the related resources. If a property has a relationship, you can call it as a method and the additional calls are automatically made & returned. The value is stored in place of the original data, so once it is loaded it is cached.

You may also call these relationships as attributes, and the Client will return a Collection for you (just like Eloquent).

Collections

Results are wrapped in a Spinen\Halo\Support\Collection, which extends Illuminate\Support\Collection, so you can use any of the collection helper methods documented Laravel Collection methods.

Filtering using "where"

You can do filters by using where on the models. The first parameter is the property being filtered. The second is optional, and is the value to filter the property. If it is left null, then is it true, so it becomes where('<property', true). All of these values are passed in the query string.

There are a few "helper" methods that are aliases to the where filter, to make the calls more expressive.

whereId('<id>') is an alias to where('id', '<id>')
whereNot('<property>') is an alias to where('<property', false)

NOTE: Halo's API need the string "true"/"false" for boolean values, which is automatically convert at time of building the query string.

Search

There is a simple search that you can preform on the endpoints using the search. There are some of the endpoints that allow searching specific fields, which you can access via search_some_field('<for>') or searchSomeField('<for>').

> $user->halo()->clients->count()
= 9

// Only clients with a "y" in the name
> $user->halo()->clients()->search('y')->get()->pluck('name')
// Same as: $user->halo()->clients()->where('search', 'y')->get()->pluck('name')
= Spinen\Halo\Support\Collection {#5136
    all: [
      "Terry's Chocolates",
      "Tony's Tyre Emporium",
    ],
  }

Limit records returned

You can call the take or limit methods (take is an alias to limit) on the builder to limit the records returned to the count parameter.

> $builder->tickets()->take(7)->get()
= Spinen\Halo\Support\Collection {#4999
    all: [
      Spinen\Halo\Ticket {#4991
        +exists: true,
        +incrementing: false,
        +parentModel: null,
        +wasRecentlyCreated: false,
        +timestamps: false,
      },
      // more...
    ],
  }

> $tickets->count()
= 7

Order By

You can order the results of the API by using the orderBy and orderByDesc methods. Pass in the column you wish to order the results as the first parameter. orderByDesc('<column>') is an alias to orderBy('<column>', 'desc'). Additionally, you can use latest or oldest to apply orderBy or orderByDesc with the default of the column in the model that represents when the record was created. You can pass a different column to either of the methods to override the default column.

// Running through map to convert date to string
> $builder->tickets()->take(5)->oldest()->get()->pluck('dateoccurred', 'id')->map(fn($d) => (string)$d)
= Spinen\Halo\Support\Collection {#4983
    all: [
      1125 => "2019-12-14 13:30:00",
      1128 => "2019-12-14 13:30:00",
      1131 => "2019-12-14 13:30:00",
      1134 => "2019-12-14 13:30:00",
      1137 => "2019-12-14 13:30:00",
    ],
  }

> $builder->tickets()->take(5)->latest()->get()->pluck('dateoccurred', 'id')->map(fn($d) => (string)$d)
= Spinen\Halo\Support\Collection {#4763
    all: [
      2205 => "2021-03-24 11:35:40",
      2206 => "2021-03-24 10:23:47",
      2200 => "2021-03-23 16:44:00",
      2186 => "2021-03-23 14:17:57",
      2187 => "2021-03-23 14:17:57",
    ],
  }

NOTE: The column to use for the latest is controlled by the CREATED_AT const on the models.

Pagination

Several of the endpoints support pagination. You can use simple pagination by chaining pagination or pageination with an optional size value to the builder. You can get a specific page with the page method that takes page number as a parameter. You can condense the call by passing pagination size as the second parameter to the page method.

// Could have been $builder->users()->paginate(2)->page(2)->get()
> $builder->users()->page(3, 2)->get()
= Spinen\Halo\Support\Collection {#4761
    all: [
      Spinen\Halo\User {#4763
        +exists: true,
        +incrementing: false,
        +parentModel: null,
        +wasRecentlyCreated: false,
        +timestamps: false,
      },
      // more...
    ],
  }

> $users->count()
= 2

      18 => "Approved",
      17 => "Awaiting Approval",
      9 => "Closed",
