reseller
PUT /v1/reseller/legal-entity
Save the company details your clients' invoices are issued under.
Authentication
Send an API key as a bearer token. The key must carry the reseller.manage permission; a key without it is refused with 403, not 404.
Where your organisation id goes
This endpoint takes org_id as a query parameter. Leave it out and the call covers your whole tenancy subtree; send it to narrow the call to one organisation.
Your organisation id is on the API keys screen in your dashboard, beside the key itself. It is the same id in every call you make.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.

-d '{ "name": <string>, "country": <string>, "number_prefix": <string> }'Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
Creates the entity the first time and updates it afterwards — never a second row. `number_prefix` is **globally unique across every company on the platform** because it is what keeps two issuers' invoice numbers apart, so a value already in use is a 409; and it **freezes once an invoice has been issued** under this company, because releasing it would let the next taker mint numbers you have already issued. Everything else stays editable — a company that moves office must be able to say so. Requires `reseller.manage`.
