# Migration Guide
This is a guide to help you make the switch when the SparkPost PHP library changes major versions.
## Migrating from 1.0 to 2.0
## Package name change
The composer package name has changed from `sparkpost/php-sparkpost` to `sparkpost/sparkpost`
### No more setupUnwrapped
We replaced the idea of 'wrapping' API resources with a simple `request` function. To see it in action, check out this [example](https://github.com/SparkPost/php-sparkpost/tree/2.0.0#send-an-api-call-using-the-base-request-function).
### `transmission` becomes `transmissions`
Transmission endpoints are now under `$sparky->transmissions` instead of `$sparky->transmission` to map more directly to the [API docs](https://developers.sparkpost.com/api/).
* We no longer map parameters to the API - we simplified. Instead custom mapping, now set the payload to match the API docs.
* The exceptions to the previous statement are `cc` and `bcc`. They are helpers to make it easier to add cc and bcc recipients. [Example](https://github.com/SparkPost/php-sparkpost/tree/2.0.0#send-an-email-using-the-transmissions-endpoint)
### Switched from Ivory Http Adapter to HTTPlug
Ivory Http Adapter was deprecated in favor of HTTPlug.
### Asynchronous support
We addeded in support for [asynchronous calls](https://github.com/SparkPost/php-sparkpost/tree/2.0.0#asynchronous) (assuming your client supports it).
### Example
#### 2.0
```php
try {
$sparky->setOptions([ 'async' => false ]);
// Build your email and send it!
$results = $sparky->transmissions->post([
'content'=>[
'from'=>[
'name' => 'From Envelope',
'email' => 'from@sparkpostbox.com>'
],
'subject'=>'First Mailing From PHP',
'html'=>'Congratulations, {{name}}!
You just sent your very first mailing!
',
'text'=>'Congratulations, {{name}}!! You just sent your very first mailing!',
],
'substitution_data'=>['name'=>'YOUR FIRST NAME'],
'recipients'=>[
[
'address'=>[
'name'=>'YOUR FULL NAME',
'email'=>'YOUR EMAIL ADDRESS'
]
]
]
]);
echo 'Woohoo! You just sent your first mailing!';
} catch (\Exception $err) {
echo 'Whoops! Something went wrong';
var_dump($err);
}
```
