Mailgun - Lists
|
|
|
|
|
====================
|
|
|
|
|
|
|
|
|
|
This is the Mailgun PHP *Lists* utilities.
|
|
|
|
|
|
|
|
|
|
The below assumes you've already installed the Mailgun PHP SDK in to your project. If not, go back to the master README for instructions.
|
|
|
|
|
|
|
|
|
|
There is currently one utility provided.
|
|
|
|
|
|
|
|
|
|
OptInHandler: Provides methods for authenticating an OptInRequest.
|
|
|
|
|
|

|
|
|
The typical flow for using this utility would be as follows:
|
|
|
|
|
**Recipient Requests Subscribe** -> [Validate Recipient Address] -> [Generate Opt In Link] -> [Email Recipient Opt In Link]
|
|
|
|
|
**Recipient Clicks Opt In Link** -> [Validate Opt In Link] -> [Subscribe User] -> [Send final confirmation]
|

|
|
|
|
|
|
|
|
The above flow is modeled below.

Here's how to use Opt-In Handler to validate Opt-In requests.
|
|
|
|
|
|
|
|
|
|
```php

2013-08-17 01:01:08 +04:00
|
|
|
# First, instantiate the SDK with your API credentials, domain, and required parameters for example.

$mg = new Mailgun('key-example');

$mgValidate = new Mailgun('pub-key-example');

# Next, generate a hash.
|

|
|
|
|
|
|
|
|
|
|
# Now, let's send a confirmation to the recipient with our link.
|
|
|
|
|
$mg->sendMessage($domain, array('from' => 'bob@example.com',

|
|
|
|
|
|
|
|
|
|
# Finally, let's add the subscriber to a Mailing List, as unsubscribed, so we can track non-conversions.
|
|
|

A few notes:
|
|
|
|
|
1. 'a_secret_passphrase' can be anything. It's used as the *key* in hashing, since your email address will vary.
|
|
|
|
|
2. validateHash() will return an array containing the recipient address and list address.
|
|
|
|
|
3. You should *always* send an email confirmation before and after the subscription request.
|
|
|
|
|
4. WARNING: On $_GET['hash'], you need to sanitize this value to prevent malicious attempts to inject code.
