README

This package provides a PHP wrapper for the FocusVision Decipher API, along with binding for using it in Laravel applications.

Installation

Install with composer:

composer require mrdth/decipher-api

Usage In Laravel

Add two new env vars:

• DECIPHER_API_URI_BASE - base URI for the decipher api (E.g. https://v2.decipherinc.com/api/v1/)
• DECIPHER_API_KEY - API key for the application

The package will be auto-registered, and can be accessed via it's facade.

All calls to the API via the wrapper should be carried out inside a try - catch block; The wrapper does not deal with any Exceptions thrown by the underlying Guzzle client.

$directory = 'selfserve/99d';
$survey_id = '12345';

\Decipher::setServerDirectory($directory)->setSurveyId($survey_id);

try {
    $survey_structure = \Decipher::getSurveyStructure('json');
  
    // Do whatever with $survey object
} catch (\GuzzleHttp\Exception\RequestException $e) {
    echo 'Error making request, server responded: ' . $e->getCode();
}

Usage as a standalone PHP Package

use MrDth\DecipherApi\Factories\Client;
use MrDth\DecipherApi\Decipher;

$api_uri = 'https://v2.decipherinc.com/api/v1/';
$api_key = 'OBVIOUSLYFAKEAPIKEY';
$directory = 'selfserve/99d';
$survey_id = '12345';

$client = new Client($api_uri, $api_key);
$decipher = new Decipher($client, $api_uri, $api_key);

All calls to the API via the wrapper should be carried out inside a try - catch block; The wrapper does not deal with any Exceptions thrown by the underlying Guzzle client.

$decipher->setServerDirectory($directory)->setSurveyId($survey_id);

try {
    $survey_structure = $decipher->getSurveyStructure('json');
  
    // Do whatever with $survey object
} catch (\GuzzleHttp\Exception\RequestException $e) {
    echo 'Error making request, server responded: ' . $e->getCode();
}

Methods exposed via the wrapper

• getSurveyList() - Get a list of all surveys available with the current API key.
• setServerDirectory(string $directory) - Directory where your projects are stored on the decipher server
• setSurveyId(int $id) - Set the ID of the current survey to work with.
• setCondition(string $condition) - Condition required to retrieve the participant. This is a Python condition as if you would enter in survey logic or crosstabs. For example, “qualified and q3.r2” retrieves only participants that were qualified and answered q3 as r2.
• getSurveyStructure(string $format) - Retrieve the structure of available questions for a survey, returning htem in the specified format. Valid formats are: html, json, text, tab
• getSurveyData(array $fields = ['all'], string $format = 'json') - Retrieve the responses to the question IDs passed in $fields from Decipher. Note: uuid & status fields will always be returned. Any condition set using ::setCondition() will be applied
• getSurveyFile(string $filename) - Retrieve the survey file called $filename as a string.
