REST API

The extension provides two kinds of API functionality:

1. Add E-Invoice content to Magento Sales APIs (invoice/credit memo GET)
2. Custom endpoints to trigger generation (invoice/credit memo + bulk)

Include E-Invoice in Invoice / Credit Memo API

Enable it in Stores >Configuration > MageB2B > E-Invoice > REST API Settings:

• Include E-Invoice in Invoice API
• Include E-Invoice in Credit Memo API

When enabled, GET responses include extension attributes:

• extension_attributes.einvoice_xml (XML string)
• extension_attributes.einvoice_pdf (base64-encoded PDF content, only for hybrid formats)

Examples:

GET /rest/V1/invoices/{invoiceId} GET /rest/V1/creditmemos/{creditmemoId}

Trigger Generation via REST

The module registers custom endpoints:

POST /rest/V1/einvoice/invoice/{invoiceId}/generate POST /rest/V1/einvoice/creditmemo/{creditmemoId}/generate POST /rest/V1/einvoice/invoices/generate POST /rest/V1/einvoice/creditmemos/generate

Notes:

• These endpoints operate on entity IDs (numeric), not increment IDs.
• Bulk endpoints use invoiceIds or creditmemoIds.
• The optional force parameter is accepted for backward compatibility.

{ "invoiceIds": [1, 2, 3], "force": true }
