# Associating connections to OpenAPI tools

## Importing an OpenAPI tool with connections

To associate an OpenAPI tool to a connection, simply specify the application id with the `-a` flag. OpenAPI tools
support only one connection per server.

To support multiple connections or non-standard headers, use a python tool.

```bash BASH theme={null}
orchestrate tools import -k openapi -f my_tool.py -a app_1
```

## How each authentication type is injected at runtime

### Basic Connections

API Keys will be injected in the headers of a request as:

```
Authorization: Basic {base64encoded(username:password)}
```

### Bearer Connections

Bearer tokens will be injected in the headers of a request as:

```
Authorization: Bearer {token}
```

### API Key Connections

API Keys will be injected in the headers of a request as:

```
x-api-key: {api_key}
```

### OAuth (all)

OAuth connections will be injected in the headers of a request as:

```
Authorization: Bearer {access_token}
```

### Key Value Connections

Key value connections are not supported.
