# dev.knotless.putSubscription

> Chooses what the asking account hears of a repository, a pull or an issue, as the appview keeps it for that account alone: no record is written. A choice counts from when it is made, and choosing the level it has already keeps it as of then. Requires authentication: a service token, or the session cookie the pages' login sets, from the pages themselves.

## Procedure (`dev.knotless.putSubscription`)

Type: procedure · POST

### Input (application/json)

- `level` (string, required): For a repository: `all` it does, its `releases` alone, or `ignore` it. For a pull or an issue: `subscribed` to every comment, or `muted`. Either way, `participating` forgets the choice, so the account hears as its part in it says; but for the account's own repository, which it hears all of until it chooses, `participating` is kept as a choice.
  - Constraints: maxLength: 64, knownValues: participating | all | releases | ignore | subscribed | muted
- `subject` (string · at-uri, required): A repository's dev.knotless.repo record, or a dev.knotless.pull or dev.knotless.issue.

### Output (application/json)

- `schema` (ref)
  - Reference: `dev.knotless.listSubscriptions#subscription`

### Errors

- `InvalidRequest`: A subject that is no repository, pull or issue, a level it cannot take, or more choices than the appview keeps for one account.
- `AuthenticationRequired`: No account asks.
- `NotFound`: No such repository the account can read, or this appview keeps no index.
