README

REMP Mailer Module is an integration module connecting CRM with REMP Mailer.

Module adds listener for NotificationEvent to send emails, and attaches widgets to allow users/admins to configure newsletter subscriptions and to see logs of all sent emails in administration.

Installing module

We recommend using Composer for installation and update management.

composer require remp/crm-remp-mailer-module

Enabling and configuring module

Add installed extension to your app/config/config.neon file.

extensions:
	remp_mailer: Crm\RempMailerModule\DI\RempMailerModuleExtension

When added, you need to provide URL of REMP Mailer instance and API token that CRM should use to communicate with Mailer.

Amend your configuration file and replace the example values with real ones:

remp_mailer:
    # Base URL where mailer is hosted.
    host: http://mailer.remp.press

    # API token to communicate with Mailer. By default the token can be acquired in REMP SSO.
    api_token: abcdef123456789

If the configuration is incomplete, initialization will log an error to your configured logger and won't enable the module in CRM.

When everything is ready, make sure you update CRM internal configuration by running following commands (they should always be part of your release process):

php bin/command.php api:generate_access
php bin/command.php application:seed

Configurable services

You can disallow subscription to newsletters for users which haven't been confirmed yet (based on users.confirmed_at DB column). The feature is disabled by default and you can enable it by adding following snippet to your config.neon:

services:
	mailerMailerConfig:
		setup:
			- setSubscribeOnlyConfirmedUser(true)

API documentation

All examples use http://crm.press as a base domain. Please change the host to the one you use before executing the examples.

All examples use XXX as a default value for authorization token, please replace it with the real tokens:

• API tokens. Standard API keys for server-server communication. It identifies the calling application as a whole. They can be generated in CRM Admin (/api/api-tokens-admin/) and each API key has to be whitelisted to access specific API endpoints. By default the API key has access to no endpoint.
• User tokens. Generated for each user during the login process, token identify single user when communicating between different parts of the system. The token can be read:
  • From n_token cookie if the user was logged in via CRM.
  • From the response of /api/v1/users/login endpoint - you're free to store the response into your own cookie/local storage/session.

API responses can contain following HTTP codes:

If possible, the response includes application/json encoded payload with message explaining the error further.
