## Update activity

`PATCH /v1/activity-configurable/:id`

Overwrites a configurable activity. `fields` and `layout` are passed in full — the method replaces the activity rather than updating individual fields. Unset values are reset.

## Parameters

| Parameter | Type | Req. | Description |
|----------|-----|:-----:|---------|
| `id` (path) | number | yes | Activity ID. Obtained on creation |

## Request fields (body)

| Field | Type | Req. | Description |
|------|-----|:-----:|---------|
| **`fields`** | object | yes | Activity fields |
| `fields.typeId` | string | no | Activity type. Defaults to `CONFIGURABLE` |
| `fields.completed` | boolean | no | Activity is closed. Accepts `true`/`false`, `1`/`0`, `Y`/`N` |
| `fields.deadline` | string | no | Due date, ISO 8601. Incompatible with `fields.isIncomingChannel` |
| `fields.pingOffsets` | number[] | no | Offsets in minutes relative to `fields.deadline` at which reminders are generated |
| `fields.isIncomingChannel` | boolean | no | Activity created from an incoming channel. Accepts `true`/`false`, `1`/`0`, `Y`/`N` |
| `fields.responsibleId` | number | no | ID of the responsible employee. List: `GET /v1/users` |
| `fields.badgeCode` | string | no | Activity badge code on the kanban |
| `fields.originatorId` | string | no | ID of the external data source |
| `fields.originId` | string | no | ID of the record in the external source |
| **`layout`** | object | yes | Activity styling |
| `layout.icon.code` | string | yes | Activity icon code |
| `layout.header.title` | string | yes | Activity title |
| `layout.body.logo.code` | string | yes | Logo code in the body. Bitrix24 rejects a body without `logo` |
| `layout.body.blocks` | object | no | Named body blocks |
| `layout.footer.buttons` | object | no | Footer buttons |

A block in `layout.body.blocks` has a `type` and `properties`. Main block types:

- `text` — value
- `link` — link with an action
- `lineOfBlocks` — a row of nested blocks
- `withTitle` — block with a caption

The action of links and buttons is defined by the `type` field:

- `redirect` — navigation to the address from the `uri` field
- `openRestApp` — opening the application with the `actionParams` parameters
- `restEvent` — an event to the application by `id`, for menu items

| 404 | `ENTITY_NOT_FOUND` | An activity with the given `id` does not exist |
| 422 | `BITRIX_ERROR` | Bitrix24 rejected the request: activity created by another application `ERROR_WRONG_APPLICATION`, `layout.body.logo` not filled, empty `layout` |

| 401 | `TOKEN_MISSING` | The authorization key was passed without a session token in the `Authorization: Bearer` header |

Full list of common API errors — [Errors](/docs/errors).

## Known specifics

**Only in application context.** An authorization key `vibe_app_*` with a session token in the `Authorization: Bearer` header is required. A personal API key `vibe_api_*` is rejected by Bitrix24 with `ERROR_WRONG_CONTEXT`.

**Only the author application updates.** Only the application that created an activity can modify it. Bitrix24 rejects another application's activity with `ERROR_WRONG_APPLICATION`.
