## Update an end-to-end analytics source

`PATCH /v1/crm-tracking/sources/:id`

`PATCH /v1/crm-tracking/sources/by-code/:code`

Updates the supplied fields of an end-to-end analytics source and returns its state after saving.

> **The method ships in the `crm 26.2100.0` update and is not yet available on all Bitrix24 accounts.** Until the feature is enabled for your Bitrix24 account, the API returns `422 METHOD_NOT_YET_AVAILABLE`.

Requires the `crm` scope and a key that permits writes.

## Parameters

| Parameter | Type | Required | Description |
|----------|-----|:-----:|---------|
| `id` (path) | number | for the ID path | Positive integer ID from the [source list](/docs/entities/crm-tracking/sources-list) |
| `code` (path) | string | for the code path | Built-in source code from the [source list](/docs/entities/crm-tracking/sources-list), such as `google` |

Choose exactly one address: `/sources/2` or `/sources/by-code/google`. Query parameters are not accepted.

The first update of a built-in source by `code` creates its record. Before saving, that source can have `id: null`.

## Request body fields

| Field | Type | Required | Description |
|------|-----|:-----:|---------|
| `name` | string | no | Source name |
| `color` | string | no | Custom source color in `#rgb` or `#rrggbb` format. A request to change a built-in source color is refused |
| `refDomains` | string[] | no | Complete list of referring domains. Built-in sources with predefined domains do not allow changes to this list |
| `utmSources` | string[] | no | Complete list of `utm_source` values |

Lists are replaced in full. `[]` clears a list. Omitted fields keep their values. Bitrix24 trims whitespace, removes empty values, and limits each list to 100 values. The API validates the shape: an array of strings.

An empty object is forwarded without adding fields. `color: null` keeps the existing color.
