# Project custom ?

This wildcard is replaced by the custom value of a specific key set via specific nodes. It is designed to hold project ID’ from third party systems. If the „Medialoopster Create Project Action“ is used to add a project to Medialoopster, the ID provided by the MediaLoopster API will be added to Helmut’s database connected to the project ID provided by Helmut. If the wildcard is used while executing a stream that is related to a project that holds a third party id, it will resolve the ID.

* {project.custom.?}
* For the following input (?) --> medialoopster
* The output is going to be —> „medialoopster project ID

The wildcard can be used according to the third party integrations that do support this wildcard. At the moment this is medialoopster.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.helmut.de/helmut4-releases/v4.6.1/helmut4-components/streamdesigner/wildcards/functional-wildcards/project-custom.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
