​
Overview

This endpoint approves a transaction waiting for approval. If enabled, transactions exceeding your configured threshold require signatures before sending them to the clearing system.

​
Prerequisites

Transaction signing must be enabled for your account. Contact Inventi team if you want to enable this

​
How It Works

  1. Create a payment that exceeds your signing threshold
  2. The system places the payment on hold with TO_SIGN status
  3. You receive a webhook notification about the status change
  4. Approve the transaction using a different API client
  5. After collecting required approvals, the payment processes automatically

​
Important Notes

​
Supported Transaction Types

Only these transaction types support signing:
  • SEPA Credit Transfers (SCT)
  • SEPA Instant Payments (INST)
  • SWIFT Payments
SEPA Direct Debit (SDD) transactions do not support signing and will never have TO_SIGN status.

​
API vs UI Approval

When your tenant has API approval enabled:
  • API-created transactions must be approved through the API by a different API client than the one that created them
  • UI-created transactions must be approved through the UI interface

​
Requirements

  • Transaction must have TO_SIGN status
  • Must use a different API client from the one that created the transaction
  • User must have approval permissions configured at the tenant level
