Requirements ------------ [](#requirements) - PHP 8.2 or higher - Composer Installation ------------ [](#installation) You can install the package via composer: ``` composer require lettermint/lettermint-php ``` Usage ----- [](#usage) Initialize the Lettermint client with your API token: ``` $lettermint = new Lettermint\Lettermint('your-api-token'); ``` ### Sending Emails [](#sending-emails) The SDK provides a fluent interface for composing and sending emails: ``` $response = $lettermint->email ->from('sender@example.com') ->to('recipient@example.com') ->subject('Hello from Lettermint!') ->text('Hello! This is a test email.') ->send(); ``` The SDK supports various email features: ``` $lettermint->email ->from('John Doe ') ->to('recipient1@example.com', 'recipient2@example.com') ->cc('cc@example.com') ->bcc('bcc@example.com') ->replyTo('reply@example.com') ->subject('Hello world!') ->html('Hello!') ->text('Hello!') ->headers(['X-Custom-Header' => 'Value']) ->attach('document.pdf', base64_encode($fileContent)) ->attach('logo.png', base64_encode($logoContent), 'logo@example.com') ->route('my-route-id') ->idempotencyKey('unique-request-id-123') ->send(); ``` #### Inline Attachments [](#inline-attachments) You can embed images and other content in your HTML emails using content IDs: ``` $lettermint->email ->from('sender@example.com') ->to('recipient@example.com') ->subject('Email with inline image') ->html('Here is an image: ') ->attach('logo.png', base64_encode($imageContent), 'logo@example.com') ->send(); ``` ### Idempotency [](#idempotency) To ensure that duplicate requests are not processed, you can use an idempotency key: ``` $response = $lettermint->email ->from('sender@example.com') ->to('recipient@example.com') ->subject('Hello from Lettermint!') ->text('Hello! This is a test email.') ->idempotencyKey('unique-request-id-123') ->send(); ``` The idempotency key should be a unique string that you generate for each unique email you want to send. If you make the same request with the same idempotency key, the API will return the same response without sending a duplicate email. For more information, refer to the [documentation](https://docs.lettermint.co/platform/emails/idempotency).
