Change a lead field
PATCH/v1/agents/:agentId/lead-fields/:fieldKey
x-scope: "leads:write"
Changes a custom field's label, whether it is required, or its choices. The key and the
type stay (to change them, add a new field). Built-in fields (built_in: true), the lead
statuses included, can't be changed through the API (422 system_field). The AI's lead
capture follows the change in the background, usually within a minute. A request that
changes nothing returns the field as it is.

Authentication failed. Single code (invalid_api_key) covers every
sub-case: missing header, wrong scheme, malformed, unknown, revoked or
expired key. The message field disambiguates for humans debugging.
One exception: when the key could not be checked because of a server-side
fault, the status is still 401 but type is internal_error and code
is internal_server_error; retry with backoff.

Authenticated, but not allowed: insufficient_scope (the key lacks the scope in this
operation's x-scope) or agent_not_authorized (the key is limited to other agents).

Per-key rate limit hit. Default is 60/min/key; an endpoint with an
x-rate-limit-per-minute of its own counts in a budget of its own
(today listWhatsAppTemplates, which allows 10/min/key, and
sendConversationMessage, which allows 20/min/key), and its 429
reports that limit in X-RateLimit-Limit. Retry-After tells you when to retry;
X-RateLimit-Reset is the Unix timestamp of the next window.
Per-success-response
X-RateLimit-*headers are a known gap; on 2xx responses these headers are NOT currently emitted. Customers should rely on 429 +Retry-Afterfor backoff signals.

Seconds to wait before retrying.
The per-minute request limit of the endpoint called. Every key has the same limits today.
Remaining requests in the current window. 0 on rejection.
Unix timestamp at which the current window resets.
Unexpected server-side failure. Retry with exponential backoff. If
the failure persists, send us the correlation_id.

changed. Retry with backoff.
