Sending emails through dynamic templates is one of the main uses of Waypoint. To send an email through a dynamic template, you can use the API call below. Within the call, you can pass data variables that are accessible from your template.

💡 New to using APIs? We recommend viewing our quick start guide with more in-depth descriptions and examples.

POST /v1/email_messages

Property	Description
templateId	The id of the template you want to send (created on the Waypoint dashboard). You can find the template ID from on each template from your templates page or grab it from the template URL. eg. wptemplate_ABc123XYZ
to	Email address of the receiver(s). It can be an email address or use the “Display Name <email address>” format. Separate multiple email addresses in comma separated string for multiple emails (eg. "joe@example.com, jane@example.com"). Max 50 recipients per message.
variables	Optional – JSON data object that is passed to the template and available as variables on the template.
from	Optional – email address of the sender. This will override a sender that has been set from the template builder and the email domain must be a verified domain within your workspace. Email address can be a string or with a name with email using the “Display Name <email address>” format.
replyTo	Optional – the email address to which replies will be sent. By default, replies are sent to the original sender's email address.
cc	Optional – email address of the receiver(s) that should be CC'd. Use the same format as 'to' attribute.
bcc	Optional – email address of the receiver(s) that should be BCC'd. Use the same format as 'to' attribute.
metaId	Optional – can be used for internal reference or idempotent requests. Eg. 'order_1234'.
groupId	Optional – unsubscribe group ID
groupKey	Optional – unsubscribe group custom key
