Use this extension when you need full control over the SEPA mandate signing process — particularly for SEPA B2B Direct Debit, which requires stricter verification than CORE. If you provide a signing service, Hellgate Commerce will delegate mandate creation and status tracking to it.
This extension is not enabled by default.Contact Hellgate Support to enable it for your account.

​
How it works

Hellgate Commerce initiates a mandate signing request and then waits for your service to report the outcome via a callback URL.

​
Callback actions

Your service posts status updates to the return_url provided at mandate creation. Each callback carries an action field:
ActionWhenKey payload fields
CREATEMandate fully signedmandate_pdf (base64 PDF), reference, signed_on
CHANGE_STATUSLifecycle state changetarget_state: ACTIVE, EXPIRED, INACTIVE, or WITHDRAWN
FAILSigning process failedOptional failure_details
TERMINATEMandate terminated by your serviceOptional failure_details
Respond with 202 Accepted for each callback. Any other status is treated as a delivery failure.
