# Update blocked spam source

`PATCH /v3/blocked_spam_sources/{id}`

Updates the `note` on a blocked spam source. `source_type` and `value` are immutable on this endpoint — to change either, delete the entry and create a new one.

## Path parameters

- `id` integer, required

## Request body

- object
  - `note` string — Replacement annotation for the blocked spam source, typically used to record why the source was added or last touched (e.g. ticket id, internal incident reference). Limited to 255 characters. `source_type` and `value` are immutable — to change either, delete the entry and create a new one.

## Response `200`

Successful

- object
  - `id` integer
  - `created_at` string, date-time
  - `updated_at` string, date-time
  - `source_type` 'ip_address' | 'cidr_block' | 'email_address' | 'email_domain' — Kind of identifier stored in `value`. `ip_address` is a single IPv4 or IPv6 address, `cidr_block` is an IPv4 or IPv6 CIDR range, `email_address` is a full address, and `email_domain` is the part after the `@`. Applications arriving from a matching source are rejected at intake with the reason `Rejected by organization blocklist`.
  - `value` string — The IP address, CIDR range, email address, or email domain to block, interpreted according to `source_type`. Stored lowercased and stripped of surrounding whitespace, so filtering by `value` is case-insensitive. Common consumer email domains (e.g. `gmail.com`, `outlook.com`, `yahoo.com`) cannot be blocked and are rejected on create.
  - `note` string, nullable — Free-text annotation set by the user who added or last updated the entry, typically used to record why the source was blocked. Limited to 255 characters; `null` when no note was provided.

## Other responses

- `401` — Unauthorized
- `403` — Forbidden
- `422` — Unprocessable Content
