# callint

`callint(path_name: str, payload: Any, extended_payload: Bool = False, force_run_mode: str = None) -> Any`

Used to call an integration from within the process of the currently running integration. `callint` will return the integration output.

| Parameters               | Description                                                                                                                                                                                                                                                                                |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `path_name`              | The integration name                                                                                                                                                                                                                                                                       |
| `payload`                | String or dict object to be used as the integration's `Input` payload.                                                                                                                                                                                                                     |
| `extended_payload=False` | See Extended Payload section below.                                                                                                                                                                                                                                                        |
| `force_run_mode=None`    | <p>Allows overriding the called integrations <code>run\_async</code> field.<br><br><code>None</code>: No override (default)<br><code>sync</code>: Force <code>run\_async</code> to be <code>False</code><br><code>async</code>: Force <code>run\_async</code> to be <code>True</code>.</p> |

```python
payload = "input_str"
x = callint("test_integration", payload)
```

{% hint style="info" %}
Integrations triggered by `callint()` will appear in the Run History.
{% endhint %}

### Extended Payload <a href="#extended-payload" id="extended-payload"></a>

When `extended_payload` is `False` (default), the called integration runs as if it was triggered from a `POST` request to `/integrations/execute/[integration_path_name]` with `payload` representing the body of the post request.

When `extended_payload` is `True`, the object passed to `payload` can have the following additional keys (all optional):

* `params`
* `path`
* `headers`
* `method`
* `fullpath`

{% hint style="info" %}
Specifics on each field can be found [here](/reference/special_variables/input.md).
{% endhint %}

This is useful for emulating the behavior of calling an integration from a [Web Services endpoint](/reference/web-service-endpoints.md). For example,

```
payload_with_method = {
    "payload": {
        "firstName": "Sally",
        "lastName": "Smith",
    },
    "method": "POST"
}

x = callint("user", payload_with_method, extended_payload=True)
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://glyue.docs.sandboxbanking.com/reference/special_functions/callint.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
