  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${accessToken}`,

## API proxy

For a api4ai endpoint with no pre-built tool, the proxy forwards your request with the connected user's credentials attached.

```bash
# The path segment is the target URL, URL-safe base64 encoded:
# https://general-detection.p.rapidapi.com/v1/algos

curl "https://api.pipedream.com/v1/connect/{project_id}/proxy/aHR0cHM6Ly9nZW5lcmFsLWRldGVjdGlvbi5wLnJhcGlkYXBpLmNvbS92MS9hbGdvcw?external_user_id={external_user_id}&account_id=apn_xxxxxxx" \
  -H "Authorization: Bearer {access_token}" \
  -H "x-pd-environment: production"
```
