Parameters

Path Parameters

contactId

required

A primary key, written as a decimal string so JavaScript never rounds it. The format makes the Go servers parse it into an int64: a malformed id is refused as a 400 before a handler runs. The pattern says the same in the contract, so a client (or a fuzzer) can tell a malformed id from a valid one without trying it. Eighteen digits is the most a key reaches, so every id the schema admits fits an int64.

string format: int64

/^[0-9]{1,18}$/
