PHP client documentation

This documentation is for developers interested in using the GOV.UK Notify PHP client to send emails, text messages or letters.

Set up the client

The Notify PHP Client is based on a PSR-7 HTTP model [external link]. To install it, you must select your preferred PSR-7 compatible HTTP client. You can follow these instructions to use Guzzle v6 and v5[external link].

Guzzle v6

1. Use Composer [external link] to install the GOV.UK Notify PHP client. Run the following in the command line:

   composer require php-http/guzzle6-adapter alphagov/notifications-php-client
   

   You can now use the autoloader [external link] to download the GOV.UK Notify PHP client.

2. Add the following code to your application to create a new instance of the client:

   $notifyClient = new \Alphagov\Notifications\Client([
       'apiKey' => '{your api key}',
       'httpClient' => new \Http\Adapter\Guzzle6\Client
   ]);
   

To get an API key, sign in to GOV.UK Notify and go to the API integration page. You can find more information in the API keys section of this documentation.

   You can now use the autoloader [external link] to download the GOV.UK Notify PHP client.

2. Add the following code to your application to create a new instance of the client:

   $notifyClient = new \Alphagov\Notifications\Client([
       'apiKey'        => '{your api key}',
       'httpClient'    => new \Http\Adapter\Guzzle5\Client(
           new \GuzzleHttp\Client,
           new \Http\Message\MessageFactory\GuzzleMessageFactory
       ),
   ]);

Send a letter

Prerequisites

When you add a new service it will start in trial mode. You can only send letters when your service is live.

To send Notify a request to go live:

1. Sign in to GOV.UK Notify.
2. Go to the Settings page.
3. In the Your service is in trial mode section, select request to go live.

Method

sendLetter( $templateId, array $personalisation = array(), $reference = '' )

For example:

try {

    $response = $notifyClient->sendEmail(
        'df10a23e-2c0d-4ea5-87fb-82e520cbf93c',
        [
            'name'=>'Fred',
            'address_line_1' => 'Foo',
            'address_line_2' => 'Bar',

        ],
        'unique_ref123'
    );

} catch (ApiException $e){}

Arguments

templateId (required)

To find the template ID:

1. Sign in to GOV.UK Notify.
2. Go to the Templates page and select the relevant template.
3. Select Copy template ID to clipboard.

personalisation (required)

The personalisation argument always contains the following parameters for the letter recipient’s address:

• address_line_1
• address_line_2
• address_line_3
• address_line_4
• address_line_5
• address_line_6
• address_line_7

The address must have at least 3 lines.

The last line needs to be a real UK postcode or the name of a country outside the UK.

Notify checks for international addresses and will automatically charge you the correct postage.

The postcode personalisation argument has been replaced. If your template still uses postcode, Notify will treat it as the last line of the address.

Any other placeholder fields included in the letter template also count as required parameters. You need to provide their values in a dictionary with key value pairs. For example:

$personalisation =
          [
            'address_line_1' => 'The Occupier',
            'address_line_2' => '123 High Street',
            'address_line_3' => 'Richmond upon Thames',
            'address_line_4' => 'Middlesex',
            'address_line_5' => 'SW14 6BF',
            'name' => 'John Smith',
            'application_id' => '4134325'
          ];

reference (optional)

A unique identifier you can create if necessary. This reference identifies a single unique notification or a batch of notifications. It must not contain any personal information such as name or postal address. For example:

$reference = 'STRING';

Testando

Todos os testes ocorrem no ambiente de produção. Não há ambiente de teste para Gov.br Notifica.

Teste de fumaça

Se você precisar de teste de fumaça no Notifica regularmente, você deve usar os seguintes números de telefone e endereços de e-mail para teste de fumaça.

 

Número de telefone
07700900000
07700900111
07700900222

Endereço de e-mail
simulate-delivered@notifications.service.gov.uk
simulate-delivered-2@notifications.service.gov.uk
simulate-delivered-3@notifications.service.gov.uk

Os números de telefone e endereços de e-mail do teste de fumaça validarão a solicitação e simularão uma resposta bem-sucedida, mas não enviarão uma mensagem real, produzirão um recibo de entrega ou manterão a notificação no banco de dados.

Você pode usar esses números e endereços de teste de fumaça com qualquer tipo de chave de API.

Você pode testar todas as funções do cliente Notificação API, exceto:

• Obtenha o status de uma mensagem
• Obtenha o status de todas as mensagens

Você não pode usar os números de telefone ou endereço de e-mail do teste de fumaça com essas funções porque eles retornam um falso notification_ID. Se você precisar testar essas funções, use uma chave API de teste e qualquer outro número de telefone ou e-mail.

Outros testes

Você deve usar uma chave de API de teste para fazer um teste sem fumaça, como teste de desempenho ou integração. Você pode usar qualquer número de telefone ou endereço de e-mail de teste que não seja de fumaça. Você não precisa de uma conta de teste específica do Gov.br Notifica.

Chaves da API

Existem três tipos diferentes de chaves de API:

• teste
• lista de equipe e de convidados
• ao vivo

Quando você configura um novo serviço, ele começa em modo de teste. Um serviço em modo de teste pode criar chaves de lista de teste e equipe e de convidados. Você deve ter um serviço ativo para criar uma chave ativa.

Para criar uma chave de API:

1. Faça login no Gov.br Notifica.
2. Vá para a página de Integração da API.
3. Selecione chaves de API.
4. Selecione Criar uma chave da API.

Teste

Use uma chave de teste para testar o desempenho de seu serviço e sua integração com Gov.br Notifica.

Mensagens enviadas usando uma chave de teste:

• gerar respostas realistas
• resulta em um status entregue
• não são realmente entregues a um destinatário
• não aparecem no seu painel
• não conte para as suas mensagens de texto e e-mail

Para testar as respostas de falha com uma chave de teste, use os seguintes números e endereços:

Número de telefone / endereço de e-mail	Resposta
07700900003	temporary-failure
07700900002	permanent-failure
temp-fail@simulator.notify	temporary-failure
perm-fail@simulator.notify	permanent-failure
qualquer outro número ou endereço válido	delivered

Você não precisa revogar as chaves de teste.

Equipe e lista de convidados

Uma chave de equipe e lista de convidados permite que você envie mensagens reais aos membros de sua equipe e endereços / números em sua lista de convidados enquanto seu serviço ainda está em modo de teste.

Você receberá um erro se usar essas teclas para enviar mensagens a alguém que não esteja em sua equipe ou na sua lista de convidados.

As mensagens enviadas com uma chave de equipe e lista de convidados aparecem em seu painel e contam em sua mensagem de texto e e-mail.

Você não precisa revogar as chaves da equipe e da lista de convidados.

Ao Vivo (Produção)

Você só pode criar chaves ativas (produção) quando o serviço estiver ativo (produção). Você pode usar as chaves ativas para enviar mensagens para qualquer pessoa.

As mensagens enviadas com uma chave ativa aparecem no seu painel e contam contra as suas mensagens de texto e e-mail.

Você deve revogar e recriar essas chaves regularmente. Para revogar uma chave:

1. Faça login no Gov.br Notifica.
2. Vá para a página de Integração da API.
3. Selecione chaves de API.
4. Selecione Revogar para a chave de API que você deseja revogar.

Você pode ter mais de uma chave ativa por vez.

Você nunca deve enviar mensagens de teste para números ou endereços inválidos usando uma chave ativa.

Limites

Limites de taxa

Você está limitado a enviar 1.000 mensagens por minuto.

Esse limite é calculado em uma base contínua, por tipo de chave de API. Se você exceder o limite, obterá o erro 429 RateLimitError.

Limites diários

Há um limite para o número de mensagens que você pode enviar por dia:

Status do serviço	Tipo de chave API	Limite diário
Ao vivo	Equipe ou ao vivo	150,000
Trial	Equipe	50
Ao vivo ou trial	Teste	Ilimitada

Esses limites são redefinidos à meia-noite.

Limites da rede telefônica

Se você enviar mensagens de texto repetidamente para o mesmo número, as redes telefônicas as bloquearão.

Existe um limite por hora de:

• 20 mensagens com o mesmo conteúdo
• 100 mensagens com qualquer conteúdo

Suas mensagens não podem ser entregues se você exceder esses limites.

Chamadas de retorno

Chamadas de retorno são quando o Gov.br Notifica envia solicitações POST para o seu serviço. Você pode obter retornos de chamada quando:

• uma mensagem de texto ou e-mail que você enviou foi entregue ou falhou <!– seu serviço recebe uma mensagem de texto –>

Configurar chamadas de retorno

Você deve fornecer:

• um URL onde o Gov.br Notifica postará o retorno para a chamada
• um token de portador que o Gov.br Notifica colocará no cabeçalho de autorização das solicitações

Para fazer isso:

1. Faça login no Gov.br Notifica.
2. Vá para a página de Integração da API.
3. Selecione Callbacks.

Recibos de entrega

Quando você envia um e-mail ou mensagem de texto, o Gov.br Notifica envia um recibo para o seu URL de retorno com o status da mensagem. Este é um método automatizado para obter o status das mensagens.

Esta funcionalidade funciona com chaves de API de teste, mas não funciona com números de telefone ou endereços de e-mail de teste de fumaça.

A mensagem de retorno de chamada é formatada em JSON. A chave, a descrição e o formato dos argumentos da mensagem de retorno de chamada serão:

Chave	Descrição	Formato
id	ID de notificação para os recibos de status	UUID
reference	A referência enviada pelo serviço	12345678
to	O endereço de e-mail ou número de telefone do destinatário	hello@gov.uk ou 07700912345
status	O status da notificação	delivered, permanent-failure, temporary-failure ou technical-failure
created_at	A hora em que o serviço enviou a solicitação	2017-05-14T12:15:30.000000Z
completed_at	A última vez que o status foi atualizado	2017-05-14T12:15:30.000000Z ou nulo
sent_at	A hora em que a notificação foi enviada	2017-05-14T12:15:30.000000Z ou nulo
notification_type	O tipo de notificação	email ou sms
