Where can I find documentation on the TMS API request/response schema and headers?

The full TMS API documentation - including endpoint definitions, request formats, response headers, and schemas for ISO 20022 messages such as pacs.002.001.12 - is available at https://github.com/tazama-lf/docs/blob/dev/Product/transaction-monitoring-service-api.md. For the Beta Sandbox, additional API documentation (including admin/config endpoints) is hosted at https://admin.beta.tazama.org/documentation. Source: Tazama Product Owner, #get-help, June 2026.
