SUMU
Taxpayers

List and retrieve taxpayers

List everything under your organisation, or fetch a single taxpayer by id.

GET/v1/api/taxpayers

Filtered and paginated, same envelope shape as List transactions: { docs, total_docs, limit, offset } under data. Ordered by name, with the id as a tiebreak so a page boundary stays stable across requests.

FieldType Description
searchstringoptionalCase-insensitive substring match against name, vat_id or cr_number
peppol_statusenumoptionalnot_registered · registered · failed · removed
limitintegeroptional1–100, default 10
offsetintegeroptionalDefault 0

total_docs counts the filtered set, not the page — keep paging until you've seen that many, not until a page comes back short.

GET /v1/api/taxpayers/{taxpayer_id} returns a single taxpayer in the same shape as Onboard a taxpayer's response, and PATCH on the same path updates any writable field.
