CreditNotes
CreditNotes
Credit note management operations.
Create, retrieve, and list credit notes with flexible querying.
Credit notes are issued by Entities to Customers and contain line items with optional taxes.
Unlike invoices, credit notes do not have a due date.
The CreditNote object
Attributes
Date the credit note was created (ISO 8601 datetime at midnight UTC)
Note for the document. If not provided, defaults to entity's document-type-specific note setting. Pass empty string to explicitly set no note.
Custom key-value data for your own use. Store any JSON object up to 50 properties. Values must be strings up to 250 characters. Useful for storing external IDs, tags, or integration data.

Taxes are calculated automatically based on the tax rates provided.
Header parameters
Entity ID on which the request is made. Auto-selected when only one entity exists, required when multiple entities exist.

}Create credit note with pre-calculated totals
/credit-notes/customCreate a credit note with pre-calculated totals from an external system.

All other logic (numbering, fiscalization, customer handling, payments, lifecycle hooks) is identical to the standard create endpoint.
Header parameters
Entity ID on which the request is made. Auto-selected when only one entity exists, required when multiple entities exist.
Body parameters
Pre-calculated document total (before tax).
Pre-calculated document total (after tax).

/credit-notesRetrieve a paginated list of credit notes with optional filtering and sorting.
Supports cursor-based pagination, flexible JSON querying with MongoDB-style operators, full-text search, and sorting.
Header parameters
Entity ID on which the request is made. Auto-selected when only one entity exists, required when multiple entities exist.
Query parameters
Number of results per request.
Default: 10
Opaque cursor to fetch the next page of results. Reuse only with the same effective ordering. Use the value from pagination.next_cursor in the previous response.
Opaque cursor to fetch the previous page of results. Reuse only with the same effective ordering. Use the value from pagination.prev_cursor in the previous response.
Whether to include the total count of items in pagination.total.
Default is true.
When false, pagination.total returns -1 for better performance.
Sort by one field or provide a repeated array for multi-column ordering. Prefix a field with - for descending order. When paginating, reuse cursors only with the same effective ordering.
JSON query object for filtering results. Supports MongoDB-style operators.
Supported operators:
- equals or direct value - Exact match (default)
- gte - Greater than or equal
- lte - Less than or equal
- gt - Greater than
- lt - Less than
- in - Value in array
- notIn - Value not in array
- contains - String contains (case-insensitive)
- startsWith - String starts with
- endsWith - String ends with
- between - Value between two numbers/dates [min, max]
Allowed fields: id, number, date, customer, customer.name, customer.email, customer.address, customer.city, customer.country, total, total_with_tax, items.name, items.description, payments.type, payments.date, document_relations.relation_type, document_relations.target_type, metadata, created_at, updated_at, paid_in_full, voided_at
Examples:
- {"total": {"gte": 1000}} - Invoices over 1000
- {"customer.name": {"contains": "Acme"}} - Customer name contains "Acme"
- {"date": {"between": ["2025-01-01", "2025-12-31"]}} - Date range
Full-text search query to filter results across multiple fields.

Searches across all text fields including names, descriptions, addresses, and metadata values.
Comma-separated list of relations to include in the response.
Available relations:
- payments - Payment records linked to this credit note
- document_relations - Linked documents (invoices, advance invoices, etc.)
Usage:?include=payments?include=payments,document_relations
