Messages

The Messages API allows you to list, search, view, modify and create email and SMS messages within your Mailosaur account.

GET/api/messages/:id

If you are using one of Mailosaur’s client libraries, we highly recommend using the .Get method instead of .GetById, as it automatically waits for results to arrive!

Retrieves the detail for a single message. Simply supply the unique identifier for the required message.

To get the ID of a message you need to call one of our other API calls which returns a list of messages. Each message in the list will contain an ID which you can use to make this call.

Path parameters

  • Name
    id
    Type
    string
    Description

    The identifier of the message to be retrieved. This can be found via other API calls such as List/Search.
