# How to Download Production Sentry Lambda Layer

You need to have the [AWS CLI](https://aws.amazon.com/cli/) installed and configured to have access to the production Sentry AWS account.

Then you can get information about the Sentry Lambda layer with this command:

```bash
aws lambda get-layer-version --layer-name arn:aws:lambda:eu-central-1:943013980633:layer:SentryPythonServerlessSDK --version-number 142
```

Make sure you have the region (in the example `eu-central-1`) and the version number (in the example `142`) to the version of the layer you want to download. If you want to download the Javascript layer use `SentryNodeServerlessSDKvX` (replacing `X` with the version of the JS SDK is in the layer) instead of `SentryPythonServerlessSDK`.

Output will be something like this:

```bash
{
    "Content": {
        "Location": "https://awslambda-eu-cent-1-layers.s3.eu-central-1.amazonaws.com/snapshots/943013980633/SentryPythonServerlessSDK-008d308b-4dc8-46c4-b7f2-48c31e187a85?versionId=xxx&X-Amz-Security-Token=xxx&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20260825T072152Z&X-Amz-SignedHeaders=host&X-Amz-Expires=600&X-Amz-Credential=xxx&X-Amz-Signature=xxx",
        "CodeSha256": "L/xPQraARPazFPwChPLlzETN2emli4UIgabUOu34bZ4=",
        "CodeSize": 9883188
    },
    "LayerArn": "arn:aws:lambda:eu-central-1:943013980633:layer:SentryPythonServerlessSDK",
    "LayerVersionArn": "arn:aws:lambda:eu-central-1:943013980633:layer:SentryPythonServerlessSDK:35",
    "Description": "",
    "CreatedDate": "2026-08-16T11:15:45.768+0000",
    "Version": 142,
    "CompatibleRuntimes": [
        "...",
        "python3.13",
        "python3.14"
    ],
    "LicenseInfo": "MIT"
}
```

Then pick the `Location` and download the layer as zip file:

```bash
curl -o layer.zip https://awslambda-eu-cent-1-layers.s3.eu-central-1.amazonaws.com/snapshots/943013980633/SentryPythonServerlessSDK-008d308b-4dc8-46c4-b7f2-48c31e187a85?versionId=xxx&X-Amz-Security-Token=xxx&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20260825T072152Z&X-Amz-SignedHeaders=host&X-Amz-Expires=600&X-Amz-Credential=xxx&X-Amz-Signature=xxx
```

Now your layer is in `layer.zip`. Enjoy!
