This post is intended to describe our 2 APIs that we have at this moment (14.11.2020), and could be updated as SMTPBOXES upgrades as well.
The first API that we are going to talk about is:
FRAPI (feedback response API).
This API serves as feedback to any web application you have by providing bounce statistics from the email letters sent via SMTPBOXES simple online platform (SOP) or your web application / SMTP Client.
With the help of the following figure, we will try to explain the entire email sending and bounce handling process. It really isn't that difficult that it seems.
Let's go from the START of this scheme and follow the workflow.
