SparkPost API Change

Hi,

Per today SparkPost changed its email API. I found this information regarding the change:

Summary of the current and future behavior The following is a summary of the current and future behavior for when a recipient is suppressed

SMTP

  • Current: return a ‘250 Ok’ and ‘policy rejection’ event (no injection event)
  • Future: return a ‘250 Ok’ with ‘injection’ event followed by a ‘bounce’ event REST API

Single recipient transmission

  • Current: return a 400 with special error message, followed by a ‘generation rejection’ event
  • Future: return a 200 with an ‘injection’ event followed by a ‘bounce’ event Multiple recipient transmission
  • Current: return a 200 followed by a ‘generation rejection’ event (no injection event)
  • Future: return a 200 with an ‘injection’ event followed by a ‘bounce’ event

When a bounce is generated due to suppression the webhook will have bounce_class of “25” and an error_code of “554” and reason of “Recipient address was suppressed due to customer policy” or “Recipient address was suppressed due to system policy”

I want to encourage anyone with the appropriate technical skill to take a look and evaluate if the changes affect the way Mautic works with SparkPost or even breaks it.

All the best,

Peter
