Every Stripe object supporting metadata accepts at most 50 key-value pairs, with keys limited to 40 characters and values to 500 characters. Both are stored as strings, so numbers and booleans round-trip as text. Exceeding any limit returns HTTP 400 with an invalid_request_error. Metadata is not indexed for the list endpoints, so it is a place to stash a foreign key, not a place to build a query surface.
On an update, setting a key to an empty string deletes that key, while passing metadata as null clears every key at once. Confirm by writing a 501-character value and reading the error. Store one identifier such as your internal order ID and fetch everything else from your own database, rather than mirroring records into Stripe where they will drift.
