Invoice Categories
GET
/v1/core/commons/invoice-categories
This endpoint is public — no API key required.
Returns the supported invoice categories.
json
{
"success": true,
"message": "Success",
"data": {
"invoice_categories": [
{ "label": "Blank", "value": "Blank" },
{ "label": "B2B", "value": "B2B" },
{ "label": "B2C", "value": "B2C" },
{ "label": "B2G", "value": "B2G" }
]
}
}Integration Enums
GET
/v1/core/commons/enums
Requires an
x-api-key header, unlike Invoice Categories above.
Returns the valid option lists for ERP system, authentication type, and data format used by a taxpayer's
integration record (erp_system, auth_type, data_format). These are
configured via the portal's dashboard rather than this API — the System Integrator API's
Update Webhook endpoint
only manages webhook_url/enabled_events on top of whatever ERP configuration
already exists.
label values are the enum's case name uppercased with spaces (e.g. DYNAMICS FO,
API KEY) — not Title Case. Use value for the actual field value you send back.
