# Publish Rust SDKs automatically

You can publish SDKs generated in Postman to crates.io. Automated publishing is supported through GitHub Actions, which can be configured to publish your SDKs to crates.io whenever a new release is created in your GitHub repository. By default, the predefined workflow creates a new release every time an automatic PR is merged.

You can also publish manually from your local machine. To learn more, see [Publish Rust SDKs manually](/docs/sdk-generator/publish/rust-manual/).

To publish your SDKs automatically, use a crates.io API token stored in GitHub secrets.

## Prerequisites

* A [crates.io account](https://crates.io).
* A verified email on the account. crates.io refuses to publish without it.
* The crate name is available, or you are an owner. Names are global and first-come, first-served.
* `Cargo.toml` includes required metadata such as `description` and `license` (or `license-file`).

## Create a crates.io API token and add it to your GitHub repo

A crates.io token (`CARGO_REGISTRY_TOKEN`) is used for authentication with the `cargo publish` command.

To create a crates.io API token and add it to your GitHub repo, do the following:

1. Sign in at [crates.io](https://crates.io) and select **Account Settings > API Tokens > New Token**.
2. Create a token with `publish-update` scope. Add `publish-new` for first publish of a new crate.
3. Restrict the token to this crate name when possible.
4. Copy the token (starts with `cio...`). It's shown only once.
5. In GitHub, select your repository and click **Settings > Secrets and variables > Actions > New repository secret**. Name it `CARGO_REGISTRY_TOKEN` and paste the token.

Publishing to crates.io is permanent. Versions cannot be deleted. Use `cargo yank` to prevent new dependents from selecting a version.
