Update gateway token key
Update gateway token key within the authenticated Telnyx account. Foreign and unknown resource IDs return the same 404 response. Omitted fields are preserved. Null clears max_parallel_requests; null resets budget and rate limits to their maximum. A stale If-Match returns 412.

Headers
24h, scoped by account+method+path. Same key/body returns same outcome; changed body 409; in-progress 409 with Retry-After. Token-create replay returns 200 metadata WITHOUT secret.
Required string length:
1 - 128Pattern:
^[A-Za-z0-9_-]+$Exact quoted resource-version ETag; an exact intermediary-weakened echo W/"n" is accepted. Wildcard, combined and malformed validators are rejected; stale 412; missing 428. HTTP field names are case-insensitive. Replayed idempotent result is checked first.
Required string length:
1 - 256Pattern:
^[^\u0000-\u001f\u007f]+$Path Parameters
Body
application/json
Optional maximum concurrent reserved/dispatched cache misses across replicas. Null means no concurrency cap. Cache hits do not consume slots; unknown usage retains its budget hold without a slot.
Required range:
1 <= x <= 1000Required string length:
1 - 256Pattern:
^[^\u0000-\u001f\u007f]+$Omitted or null defaults to the maximum (1000 USD) (on a blocked key, null is kept until the key is unblocked); a value below the minimum (0.000001 USD) or above the maximum is rejected with 400 limit_out_of_range; a malformed value (negative, wrong type or precision) is 400 invalid_request. Block the key (blocked: true) to deny it; blocking is always accepted. The default budget is lifetime unless budget_duration is set. Budgets and spend are an enforcement guard computed at one flat placeholder rate for every Telnyx-hosted model (rate_version telnyx-reference-v1: 5 USD per million input and 15 USD per million output tokens), not the customer's bill; Telnyx Inference usage is billed separately at the model's actual price.
Required range:
0.000001 <= x <= 1000Must be a multiple of 0.000001Available options:
1d, 7d, 30d, null Omitted or null defaults to the maximum (10000000) (on a blocked key, null is kept until the key is unblocked); a value below the minimum (1) or above the maximum is rejected with 400 limit_out_of_range; a malformed value (negative, wrong type or precision) is 400 invalid_request. Block the key (blocked: true) to deny it; blocking is always accepted.
Required range:
1 <= x <= 10000000Omitted or null defaults to the maximum (6000) (on a blocked key, null is kept until the key is unblocked); a value below the minimum (1) or above the maximum is rejected with 400 limit_out_of_range; a malformed value (negative, wrong type or precision) is 400 invalid_request. Block the key (blocked: true) to deny it; blocking is always accepted.
Required range:
1 <= x <= 6000Maximum array length:
1000Required string length:
1 - 256Pattern:
^[^\u0000-\u001f\u007f]+$Require a nonempty caller-asserted end-user ID; not proof of identity. Omission preserves the current requirement.
