Reverse issuance APISettlement platforms and purchasing teams

Send the details for approval. Stop waiting for an invoice.

The settlement is agreed, but the invoice has not arrived. Let the buyer prepare the transaction details so the supplier can focus on reviewing and approving them.

The buyer prepares. The supplier approves.

Send an approval request with the agreed details instead of exchanging amounts and business information again. The supplier still approves issuance.

  1. Buyer

    Prepare the settled transaction details and request reverse issuance.

  2. Supplier

    Review the request and approve it personally.

  3. Operations

    Track pending approvals, rejections, and issuance results separately.

Choose the approval path that fits your supplier workflow.

Have Bolta send the approval email, or guide suppliers to an approval URL from your service.

Reverse issuance: KRW 200 each

Reverse issuance uses prepaid credit and is separate from the service subscription.

Read the API key from a server environment variable. Do not ask for secrets in chat. Start with the documented test key and test inputs.

Test goals: For the chosen email or simple approval flow, verify pending approval, approval, rejection, and the final issuance result.

Do not invent undocumented features or responses. Identify open questions and summarize test results and production-readiness steps.

Questions before you integrate

What if the supplier does not approve?

You can check pending and rejected requests. Issuance proceeds after the supplier approves.

Do we need to build an approval screen?

Use Bolta's approval email or direct the supplier to the approval URL. The documentation explains the setup for each option.

When does the supplier register a certificate?

Email approval starts without advance certificate registration, but still requires supplier approval. Simple reverse issuance requires the supplier's certificate in advance.
