Mandrill Emails via Golang

Stripped down package for sending emails through the Mandrill API. Inspired by @mostafah's implementation.

Installation

go get -u github.com/keighl/mandrill

Upgrading to 1.0

MessagesSend() and MessagesSendTemplate() now only returns 1 error interface (as opposed to a non-sensical 2).

// New!
res, err := client.MessagesSend(m)

// Old!
res, apiError, err := client.MessagesSend(m)

client := m.ClientWithKey("XXXXXXXXX")

message := &m.Message{}
message.AddRecipient("bob@example.com", "Bob Johnson", "to")
message.FromEmail = "kyle@example.com"
message.FromName = "Kyle Truscott"

Including Merge Tags

http://help.mandrill.com/entries/21678522-How-do-I-use-merge-tags-to-add-dynamic-content-

// Global vars
message.GlobalMergeVars = m.MapToVars(map[string]interface{}{"name": "Bob"})

// Recipient vars
bobVars := m.MapToRecipientVars("bob@example.com", map[string]interface{}{"name": "Bob"})
jillVars := m.MapToRecipientVars("jill@example.com", map[string]interface{}{"name": "Jill"})
message.MergeVars = []*m.RcptMergeVars{bobVars, jillVars}

Integration Testing Keys

You can pass special API keys to the client to mock success/err responses from MessagesSend or MessagesSendTemplate.

// Sending messages will be successful, but without a real API request
c := ClientWithKey("SANDBOX_SUCCESS")

// Sending messages will error, but without a real API request
c := ClientWithKey("SANDBOX_ERROR")
