Attributes synced from a CRM integration only accept `prompt`, `should_prompt_override` and `is_visible`. **Required scope:** `CRM_WRITE` This endpoint performs a partial update. Only the fields you send are modified. `key` and `type` cannot be changed. ## Body fields | Field | Type | Description | | - | - | - | | `label` | string | New display name | | `options` | array | Replaces the full option list with `{ label, key? }` objects. `DROPDOWN` attributes only | | `prompt` | string | Instruction for the AI CRM Manager. A blank value clears it | | `should_prompt_override` | boolean | Whether the AI may overwrite a value that is already set | | `is_visible` | boolean | Show or hide the attribute in the Allo apps | ## Renaming options Option keys stay stable. To rename an option, send its current `key` with the new `label`. An option sent without a matching `key` is treated as new and gets a key derived from its label. Options missing from the list are removed. ## Attributes synced from a CRM An attribute whose `source` is not `allo` is managed by your CRM integration. Only `prompt`, `should_prompt_override` and `is_visible` can be changed. Sending `label` or `options` returns `409 ATTRIBUTE_MANAGED_BY_INTEGRATION`. ## Response Returns `200` with the updated attribute, in the same shape as [List company attributes](/en/v2/api-reference/crm/list-company-attributes). ## Errors | Status | Code | When | | - | - | - | | `400` | `ATTRIBUTE_LABEL_INVALID` | `label` is blank, longer than 255 characters, or has no letter or digit | | `400` | `ATTRIBUTE_OPTION_INVALID` | `options` is empty, or an option label is blank, longer than 255 characters or duplicated | | `400` | `ATTRIBUTE_OPTIONS_NOT_SUPPORTED` | `options` sent for an attribute that is not `DROPDOWN` | | `403` | `API_KEY_INSUFFICIENT_SCOPE` | The key does not hold `CRM_WRITE` | | `404` | `TEAM_NOT_FOUND` | The workspace is not on the new contact model | | `404` | `ATTRIBUTE_NOT_FOUND` | No attribute with this key | | `409` | `ATTRIBUTE_MANAGED_BY_INTEGRATION` | `label` or `options` sent for an attribute managed by a CRM integration | | `409` | `ATTRIBUTE_CONCURRENT_MODIFICATION` | Attributes were modified at the same time.
