About

Post Grid Print and Mail (BYOK) lets an AI assistant read your own Post Grid Print and Mail data through the Post Grid Print and Mail API with a key you supply (PostGrid Print and Mail API key (test or live)). Read-only: 10 tools (list_templates, get_template, list_letters, get_letter, list_postcards, list_self_mailers, list_trackers, list_webhooks, list_return_envelopes, list_events). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.postgrid.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Post Grid Print and Mail. Post Grid Print and Mail and its logos are trademarks of their owners and are used only to say which service the connector works with.

Sources: Live from the Post Grid Print and Mail API (api.postgrid.com) with a BYOK key; documentation: https://docs.postgrid.com/. Endpoints checked against that documentation on 2026-10-16.
