Request

Create a Message Template without providing an Id. An Id will be automatically generated.

URI

POST /api/message/template

Create a Message Template with the provided Id

URI

POST /api/message/template/{messageTemplateId}

Request Parameters

messageTemplateId [UUID] Optional defaults to secure random UUID: The Id to use for the new Message Template. If not specified a secure random UUID will be generated.

Request Body

messageTemplate.data [Object] Optional: An object that can hold any information about the Message Template that should be persisted.
messageTemplate.defaultTemplate [String (FreeMarker Enabled)] Required: The default Message Template.
messageTemplate.localizedTemplates [Map<Locale,String (FreeMarker Enabled)>] Optional: The Message Template used when sending messages to users who speak other languages. This overrides the default Message Template based on the user’s list of preferred languages.
messageTemplate.name [String] Required: A descriptive name for the Message Template (i.e. "Two Factor Code Message")
messageTemplate.type [String] Required: The type of the template. This must have the value SMS.

Update a Message Template

This API is used to update an existing Message Template.

You must specify the Id of the Message Template you are updating on the URI.

You must specify all of the properties of the Message Template when calling this API with the PUT HTTP method. When used with PUT, this API doesn’t merge the existing Message Template and your new data. It replaces the existing Message Template with your new data.

Utilize the PATCH HTTP method to send specific changes to merge into an existing Message Template.

Request

Update a Message Template by Id

URI

PUT /api/message/template/{messageTemplateId}

PATCH /api/message/template/{messageTemplateId}

Available since 1.12.0

When using the PATCH method, use the same request body documentation that is provided for the PUT request. The PATCH method will merge the provided request parameters into the existing object, this means all parameters are optional when using the PATCH method and you only provide the values you want changed. A null value can be used to remove a value. Patching an Array will result in all values from the new list being appended to the existing list, this is a known limitation to the current implementation of PATCH.

Request Parameters

messageTemplateId [UUID] Required: The Id of the Message Template to update.

Request Body

messageTemplate.data [Object] Optional: An object that can hold any information about the Message Template that should be persisted.
messageTemplate.defaultTemplate [String (FreeMarker Enabled)] Required: The default Message Template.
