## Example

```python theme={"system"}

    endpoint_connection_id=endpoint_connection_id,
    timeout=60,
    rate_limit=100,
)
```

## Parameters

<ResponseField name="endpoint_connection_id" type="string" required>
  ID of the endpoint connection to update.
</ResponseField>

<ResponseField name="name" type="string" optional>
  New name for the endpoint connection.
</ResponseField>

<ResponseField name="url" type="string" optional>
  New endpoint URL. For [multi-step session lifecycles](/concepts/product/endpoint-connection#multi-step-session-lifecycle-advanced), supports a `{{ session_id }}` placeholder (requires an `INITIALIZATION` endpoint).
</ResponseField>

<ResponseField name="http_method" type="string" optional>
  New HTTP method. Valid values: `GET`, `POST`, `PUT`, `PATCH`, `DELETE`.
</ResponseField>

<ResponseField name="auth_type" type="string" optional>
  New authentication type. Valid values: `NONE`, `BEARER`, `API_KEY`, `BASIC`.
</ResponseField>

<ResponseField name="auth_token" type="string" optional>
  New authentication token.
</ResponseField>

<ResponseField name="username" type="string" optional>
  New username for `BASIC` authentication.
</ResponseField>

<ResponseField name="password" type="string" optional>
  New password for `BASIC` authentication.
</ResponseField>

<ResponseField name="headers" type="dict[string, string]" optional>
  New custom headers. Supports credential placeholders (e.g., `{{ bearer_token }}`, `{{ api_key }}`). See [Custom Headers](/concepts/product/endpoint-connection-configuration#custom-headers).
</ResponseField>

<ResponseField name="input_template" type="string" optional>
  New input template with Jinja2 placeholders. See [Input Template](/concepts/product/endpoint-connection-configuration#input-template).
</ResponseField>

<ResponseField name="output_mapping" type="dict[string, string]" optional>
  New output mapping using JSONPath expressions. See [Output Mapping](/concepts/product/endpoint-connection-configuration#output-mapping).
</ResponseField>

<ResponseField name="timeout" type="int" optional>
  New per-attempt request timeout in seconds. Capped at `120`; values above this are rejected by the API.
</ResponseField>

<ResponseField name="rate_limit" type="int" optional>
  New maximum requests per minute. Pass `None` for no limit.
</ResponseField>

<ResponseField name="retry_enabled" type="bool" optional>
  Whether automatic retry is enabled. See [Retry Configuration](/concepts/product/endpoint-connection-configuration#retry-configuration).
</ResponseField>

<ResponseField name="retry_max_attempts" type="int" optional>
  New maximum retry attempts (0–10). `0` is only valid when retry is disabled; with retry enabled the minimum is `1`.
</ResponseField>

<ResponseField name="retry_initial_delay_ms" type="int" optional>
  New initial delay in milliseconds before first retry.
</ResponseField>

<ResponseField name="retry_backoff_strategy" type="string" optional>

  All fields except `endpoint_connection_id` default to `PydanticUndefined` (from `pydantic_core`).
  Omit a field (or pass `PydanticUndefined`) to leave it unchanged.
  Pass `None` to explicitly clear an optional field.
  Pass a value to update it.
