# AWS Secret Backend HTTP API

This is the API documentation for the Vault AWS secret backend. For general
information about the usage and operation of the AWS backend, please see the
[Vault AWS backend documentation](/docs/secrets/aws/index.html).

This documentation assumes the AWS backend is mounted at the `/aws` path in
Vault. Since it is possible to mount secret backends at any location, please
update your API calls accordingly.

## Configure Root IAM Credentials

This endpoint configures the root IAM credentials to communicate with AWS. There
are multiple ways to pass root IAM credentials to the Vault server, specified
below with the highest precedence first. If credentials already exist, this will
overwrite them.

The official AWS SDK is used for sourcing credentials from env vars, shared
files, or IAM/ECS instances.

- Static credentials provided to the API as a payload

- Credentials in the `AWS_ACCESS_KEY`, `AWS_SECRET_KEY`, and `AWS_REGION`
  environment variables **on the server**

- Shared credentials files

- Assigned IAM role or ECS task role credentials

At present, this endpoint does not confirm that the provided AWS credentials are
valid AWS credentials with proper permissions.
