With the rapidmail API 3.0, you have access to the following functionalities

  • Mailings
    • Send mailings from a zip file
    • List mailings
    • Get details of a single mailing
    • Get mailing statistics

Getting access to the API

To access the API you need a rapidmail account. You can create an account here. Then you need to create an API user. To do this, log into your rapidmail account, and access the API user management interface via Settings › API


The rapidmail API 3.0 supports HTTP Basic Authentication. Please see the following example on how to use curl to make an authenticated request:

                    curl --request GET \
                    --url '' \
                    --user 'apiusername:apipassword'

API structure

Our API uses a RESTful architecture throughout. Most of the API is self-describing (see HATEOAS) using HAL where appropriate.

Data format

Our API uses the JSON format. Accept and Content-Type headers should always be "application/json" unless specified otherwise in the respective services' documentation. Related links (e.g. for pagination) will be provided using HAL. Please see the following sample response for a paginated recipient list.

                            "self": {
