Holded API updates: Webhooks, MCP server, and key limitations detailed

Holded's API has been updated with new features including webhooks and an MCP server, but developers should be aware of certain limitations. While webhooks cover creation, update, and deletion events for contacts, invoices, and payments, they do not support invoice due date notifications, necessitating continued scheduled polling for such tasks. The API also has a monthly request quota that varies by plan, which can be quickly consumed by frequent polling, requiring careful management of API calls. Furthermore, updates to records via API v2 replace the entire record, meaning developers must read, merge, and then write the full object to avoid data loss. The official MCP server, usable with models like Claude and ChatGPT, offers read-only analytics and limited operational capabilities, deliberately restricting write access to sensitive accounting data like invoices.
