Update writing style

Change a style’s name or voice configuration, or make it the scope’s default. surface and channel are immutable — there is no path to change either after creation.


PATCH /brands/{brand_id}/writing-styles/{style_id}

Authorization

Header	Type	Required
`Authorization`	`Bearer asky_sk_…`	required
`Idempotency-Key`	`string`	required on every write. See Idempotency

Path parameters

Parameter	Type	Required	Description
`brand_id`	`uuid`	required	From List brands
`style_id`	`uuid`	required	From List writing styles

Body parameters

All optional; send only what changes. At least one of these, or is_default, is required.

Parameter	Type	Description
`name`	`string`	1 to 60 characters. Must stay unique within this style’s scope
`tone_of_voice`	`object`	Replaces the whole object, not a per-key merge. `presets` entries must exactly match one of `Expert`, `Conversational`, `Confident`, `Educational`, `Bold`, `Empathetic`, `Direct`, `Approachable`, `Storytelling` — anything else belongs in `custom_tones`, which is free text
`writing_rules`	`object`	Replaces the whole object, not a per-key merge
`heading_case_style`	`string`	`sentence` or `title`. Content styles only
`translation_formality`	`string \| null`	`default`, `prefer_more`, `prefer_less`, or `null` to clear it. Content styles only
`competitor_statistics_mode`	`string \| null`	`ask`, `include`, `exclude`, or `null` to clear it. Content styles only
`english_variant`	`string \| null`	`us`, `uk`, or `null` to clear it. Content styles only
`language_overrides`	`object`	Replaces the whole object. Social styles only
`is_default`	`boolean`	Must be `true` if present. There is no way to unset a default through this field — set a different style as default instead

Response fields

Same shape as Get writing style’s data — the current state of the style after applying the update.

Errors

Status	Code	When
400	`invalid_request`	No fields provided, a content-only field sent for a social style, `language_overrides` sent for a content style, or another malformed field. The message names it
401	`invalid_token`	The key is missing, malformed, or does not exist
401	`token_expired`	The key passed its expiry date
401	`token_revoked`	The key was revoked
404	`not_found`	The style does not exist for this brand, or this key is not allowed to reach the brand
409	`conflict`	The new name collides with another style already in this scope
429	`rate_limited`	Over 60 requests per minute on write endpoints

Notes

tone_of_voice and writing_rules are whole-object replacements, not merges. Sending writing_rules with only always_do set overwrites never_do back to []. Fetch the current style first if you only want to change part of it.

is_default only ever sets, never unsets. {"is_default": false} is rejected outright — the field only accepts true. To remove a style as the default, set a different style as the default instead; a scope is never left without one as long as it has at least one style.

Setting is_default: true and other fields in the same request applies both, but as two separate underlying operations: the field changes, then the default swap. If the swap fails after the fields already saved, you get a 500 and the fields are still changed — retry the request (same Idempotency-Key behavior applies) rather than assuming nothing happened.
