Golang SDK

​

Summary

• Revamped email sending to use SendEmailRequest instead of positional arguments.
• Aligned events querying and webhook creation with GetEventsRequest and WebhookCreateRequest.

​

Details

• Added SendEmailRequest with From, To, Subject, Text, Html, Cc, Bcc, ReplyTo, Attachments, Headers, and Tags.
• Updated EmailsService.Send signature to Send(req *SendEmailRequest) (*EmailResponse, error).

• Added GetEventsRequest with StartDate, EndDate, Event, MessageID, StartFrom, and RetrieveCount.
• Updated EventsService.Get signature to Get(req *GetEventsRequest) (*EventsResponse, error).
• All fields are optional; nil means no filters (GET /events).

• Reused WebhookCreateRequest as the user-facing create payload.
• Updated WebhooksService.Create signature to Create(req *WebhookCreateRequest) (*WebhookCreateResponse, error).

​

Breaking Changes

• EmailsService.Send no longer supports the old 12-argument signature.
• EventsService.Get and WebhooksService.Create now require struct-based request payloads.
• Existing integrations must migrate to request structs.

​

Migration Example

func main() {
	sl := sendlayer.New(os.Getenv("SENDLAYER_API_KEY"))

	resp, err := sl.Emails.Send(
		"paulie@example.com",
		"recipient@example.com",
		"Test Email",
		"This is a test email",
		"",
		nil, nil, nil,
		nil, nil, nil,
	)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println("Email sent! Message ID:", resp.MessageID)
}

func main() {
	sl := sendlayer.New(os.Getenv("SENDLAYER_API_KEY"))

	resp, err := sl.Emails.Send(&sendlayer.SendEmailRequest{
		From:    "paulie@example.com",
		To:      "recipient@example.com",
		Subject: "Test Email",
		Text:    "This is a test email",
	})
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println("Email sent! Message ID:", resp.MessageID)
}
