I am getting this error after forking the Postman API:

```auto
{
    "title": "The specified parameter is in an invalid format",
    "detail": "Parameter, apiId is in an invalid format.",
    "type": "invalidParamsError"
}

```

I have an API Key, but your documentation and help has apparently never seen this error coming from your API.

Hey @trisyswhatsapp 👋🏼

Are you able to share a screenshot of the request where you’re using the parameters and a link to the request in the documentation, please?

Hi Danny

Thanks for your reply.

Here is the screenshot of Postman showing the first attempt to call a Postman API:

Please note that I am a Postman customer and have used it for years so I generally know how things work, but your documentation at [Postman API | Get Started | Postman API Network](https://www.postman.com/postman/postman-public-workspace/collection/i2uqzpp/postman-api) is very unclear as to what this “apiId” is?

I have an API Key, but the internet, AI engines and your help knows nothing about “ApiId”

Kind Regards, Garry.

Hey 👋🏼

What’s the path parameter that you’re using for the `apiId` in the URL? You can see this by selecting the `Params` section.

That should be the Id of the API you’re working with.

This is not the same as an API Key to access the Postman API.

The latest version of the Postman API documentation can be found here:

> **[Postman](https://www.postman.com/postman/postman-public-workspace/collection/i2uqzpp/postman-api?action=share&source=copy-link&creator=8213448)**

I believe this is the request that you’re using:
