Generate pain XML from records
generate_messageRead-onlyIdempotent
Convert in-memory payment records into validated ISO 20022 pain XML, returning the message or all validation errors at once.
Instructions
Generate a validated ISO 20022 pain XML message from in-memory records.
This is the primary generation tool: pass records you already hold in
memory. Use ``generate_message_from_file`` when the data lives in a CSV
on disk, and ``generate_message_async`` for very large batches you want
to run off the event loop. The result is XSD-validated before return; no
file is written.
Records are normalized before rendering: 'amount'/'currency' aliases,
JSON booleans, and bare 'YYYY-MM-DD' dates are accepted, and
nb_of_txs/ctrl_sum are computed from the records. On failure the
``{"error": ...}`` payload lists every missing or invalid field at
once. IBAN/BIC values are strictly validated, never coerced.
Returns the validated XML document as a string, or a JSON-encoded
``{"error": ...}`` payload if generation fails.
Args:
message_type: A supported ISO 20022 pain message type.
records: One or more flat payment records.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| records | Yes | One or more flat payment records (dicts of field name → value). Key fields (see get_input_schema for the full contract): id, date (payment-initiation timestamp; 'YYYY-MM-DD' is accepted and rendered as midnight), initiator_name, payment_id, requested_execution_date ('YYYY-MM-DD'), debtor_name, debtor_account_IBAN, debtor_agent_BIC, creditor_name, creditor_account_IBAN, creditor_agent_BIC, payment_amount (alias: 'amount'; max two decimals), currency (alias: 'payment_currency'; ISO 4217, e.g. 'EUR'), remittance_information. batch_booking accepts JSON true/false. nb_of_txs and ctrl_sum are computed automatically from the records and may be omitted. payment_method defaults to 'TRF' and charge_bearer to 'SLEV'. IBAN and BIC values are strictly validated and never coerced. | |
| message_type | Yes | A supported ISO 20022 pain message type. Must be exactly one of: 'pain.001.001.03', 'pain.001.001.04', 'pain.001.001.05', 'pain.001.001.06', 'pain.001.001.07', 'pain.001.001.08', 'pain.001.001.09', 'pain.001.001.10', 'pain.001.001.11', 'pain.001.001.12', 'pain.001.001.13', 'pain.008.001.02', 'pain.008.001.08', 'pain.001', 'pain.008' (see list_message_types). The bare family names 'pain.001' and 'pain.008' are accepted as aliases for 'pain.001.001.09' and 'pain.008.001.02'. |
