-Mailpit provides a simple REST API to access and delete stored messages.
-
-If the Mailpit server is set to use Basic Authentication, then API requests must use Basic Authentication too.
-
-You can view the Swagger API documentation directly within Mailpit by going to https://mailpit.axllent.org/docs/api-v1/.

-The API is split into four main parts:
-
-- [Messages](Messages.md) - Listing, deleting & marking messages as read/unread.
-- [Message](Message.md) - Return message data & attachments
-- [Tags](Tags.md) - Set message tags
-- [Search](Search.md) - Searching messages
