> Fetch the complete documentation index at: https://docs.photon.codes/docs/llms.txt
> Use this file to discover all available pages before exploring further.

> ## Agent Instructions
> Use Stable documentation by default. Honor an explicit Beta request or a URL under /docs/beta/. If the requested version conflicts with the installed CLI package or API origin, clarify the target before writing integration code.
> Pages under /docs/beta/ document Beta; other product pages document Stable. Keep the CLI package, commands, API origin, and credentials within the selected version. State the documentation version in your answer.
> For MCP search, always pass version: Stable or version: Beta. Unfiltered search mixes both versions. For filesystem reads, keep Beta queries under /beta/ and exclude /beta/ from Stable queries; discover paths before reading them.
> The public docs base is https://photon.codes/docs. Convert MCP page paths to public URLs under that base, preserving /beta/ when present. Read https://photon.codes/docs/skill.md for version selection and https://photon.codes/docs/llms.txt for the version indexes.

# Count Users

> Count Users: countUsers in the TypeScript, Python, Rust and Go clients.

`GET /v1/projects/{id}/users/count`

Counts distinct Users matching the list filters, including incoming senders or outgoing recipients selected by Message filters. Results are eventually consistent.

**TypeScript**

```typescript TypeScript theme={null}
photon.projects.countUsers(input: CountUsersInput, options?: RequestOptions): Promise<CountUsersOutput>
```

**Python**

```python Python theme={null}
photon.projects.count_users(input: CountUsersInput) -> models.UserCount
```

**Rust**

```rust Rust theme={null}
client.count_users(id: String, params: Option<CountUsersParams>).await -> Result<ResponseValue<types::UserCount>, Error<CountUsersError>>
```

**Go**

```go Go theme={null}
client.Projects.CountUsers(ctx context.Context, params *CountUsersParams, opts ...RequestOption) (*UserCount, error)
```

```typescript TypeScript theme={null}
import { Photon } from "@photon-ai/api";

const photon = new Photon({
  headers: { Authorization: `Bearer ${process.env.PHOTON_API_TOKEN}` },
});
const result = await photon.projects.countUsers({
  path: {
    id: "id",
  },
});
```

```python Python theme={null}
import os

from photon_api import Photon
from photon_api.rpc_generated import CountUsersInput

photon = Photon(headers={"Authorization": f"Bearer {os.environ['PHOTON_API_TOKEN']}"})
result = photon.projects.count_users(
    CountUsersInput.model_validate({
        "path": {
            "id": "id",
        },
    })
)
```

```rust Rust theme={null}
use photon_ai_api::{Credential, PhotonClientBuilder, SecretString};

let token = std::env::var("PHOTON_API_TOKEN")?;
let client = PhotonClientBuilder::new()
    .credential("accountServiceKey", Credential::Bearer(SecretString::from(token)))
    .build()?;
let result = client
    .count_users("id".to_owned(), None)
    .await
    .map_err(|error| format!("{error:?}"))?
    .into_inner();
```

```go Go theme={null}
import (
	"context"
	"os"

	photonapi "github.com/photon-hq/api/packages/go"
)

ctx := context.Background()
client := photonapi.NewClient(photonapi.WithAPIKey(os.Getenv("PHOTON_API_TOKEN")))
result, err := client.Projects.CountUsers(ctx, &photonapi.CountUsersParams{
	ID: "id",
})
if err != nil {
	return err
}
_ = result
```

```json 200 theme={null}
{
  "count": 0
}
```

## Parameters

**id** `string` *required*

**messageCreatedBefore** `string (date-time)`

Exclusive creation-time bound on a matching Message

**messageCreatedSince** `string (date-time)`

Inclusive creation-time bound on a matching Message

**messageDirection** `MessageDirection`

Received or sent Message. All message-prefixed filters must match the same Message.

**messageExcludeContentTypes** `string`

Comma-separated public content types to exclude from matching Messages. Requires messageResourceId. A group is excluded when its type or all its parts are excluded.

**messageResourceId** `string`

Resource ownership captured by a matching Message

**createdBefore** `string (date-time)`

Exclusive upper bound on createdAt, RFC 3339. Cannot combine with updatedAt bounds.

**createdSince** `string (date-time)`

Inclusive lower bound on createdAt, RFC 3339. Cannot combine with updatedAt bounds.

**platform** `Platform`

Restricts the page to one platform

**updatedBefore** `string (date-time)`

Exclusive upper bound on updatedAt, RFC 3339. Cannot combine with createdAt bounds.

**updatedSince** `string (date-time)`

Inclusive lower bound on updatedAt, RFC 3339. Cannot combine with createdAt bounds.

## Returns

**`200`** Number of matching Users UserCount

**count** `integer` *required*
