Mark an invoice paid
The invoices.mark_paid operation: POST /api/v1/invoices/{id}/mark_paid in the REST API and the invoices_mark_paid tool in the MCP server.
/api/v1/invoices/{id}/mark_paidRecords that the customer paid an open (or uncollectible) invoice in full by bank transfer: the day the money
arrived (paidOn, on or after the issue date, not in the future) and the transfer's reference as it appears on
the bank statement. The ledger moves the amount due from the brand's receivables to the entity's bank account
(for an uncollectible invoice, it recovers the bad debt). Emits invoice.paid. For a subscription invoice,
the payment also applies what it waited for: an incomplete subscription activates, its discounts count, and a
past-due or unpaid subscription is active again (subscription.recovered).
Only full payments: partial or unclear transfers wait in the bank reconciliation review. Financial tier: an approval policy may require a second person; dry-run it first.

Errors
| Code | HTTP status | When | What to do |
|---|---|---|---|
validation_failed | 400 | paidOn is in the future or before the issue date, or the reference is missing. | Fix the fields listed in details.issues and send the request again. |
resource_not_found | 404 | This brand has no such invoice in this mode (invoices belong to one brand and one mode). | Check the ID and that your credentials are scoped to the right organization, entity, brand and mode. |
invoice_status_invalid | 409 | Only open and uncollectible invoices are marked paid. | Check the invoice's status (details.status) and what it still allows (details.allowed_actions). Drafts are edited and finalized; open invoices are sent, paid, voided or marked uncollectible; paid and void invoices don't change (corrections are credit notes). |
version_conflict | 409 | The invoice changed since expectedVersion, or at the same moment; read it again and retry. | Fetch the object again and retry the change. |
idempotency_key_reused | 409 | The idempotency key was used before for another request. | Use a new Idempotency-Key for a different request, or resend the original request unchanged. |
approval_required | 202 | The organization's approval policy needs a second person for this; nothing changed yet. | Nothing ran yet. An approver reviews approval.summary and the dry-run result in the console (approval.approveUrl). Poll GET /approvals/{id} or watch for the approval.resolved event; sending the same request again with the same Idempotency-Key returns the same approval. |
approval_rejected | 409 | The same request was sent again after it was rejected. | Read the reason in details.approval.rejection. To try again, send a new request with a new Idempotency-Key. |
approval_expired | 409 | The same request was sent again after its approval request expired. | Send the request again with a new Idempotency-Key to create a new approval request. Requests expire after 72 hours. |
stale_approval | 409 | The approved request could no longer run as requested. | Check the current state (details.approval.failure says what failed), then send a new request with a new Idempotency-Key. |
scope_required | 400 | The request names no brand (an org or entity key without Ownrecord-Brand). | Call the operation with credentials or a target at its level: an organization, a legal entity, a brand or the platform (details.required_scope). |
permission_denied | 403 | You can't change this brand's invoices (invoices:write: finance, owners and admins). | Ask an organization owner or admin for a role or scope that allows this action. |
livemode_not_allowed | 403 | You have no live-mode access, so you can't use live invoices. | Use test mode, or credentials for the target's mode. Developers need live access granted by an organization owner or admin. |
It can also return these common errors: api_version_unsupported, invalid_json, unsupported_media_type, authentication_required, api_key_invalid, idempotency_key_required, idempotency_in_progress, approval_policy_denied, rate_limited, internal_error.
