I'm the creator of **FastAPI**. You can read more about that in [Help FastAPI - Get Help - Connect with the author](help-fastapi.md#connect-with-the-author).

...But here I want to show you the community.

---

**FastAPI** receives a lot of support from the community. And I want to highlight their contributions.

These are the people that:

touchend.timepicker",{scope:this},this.handleDocumentClick),this.$element.trigger({type:"show.timepicker",time:{value:this.getTime(),hours:this.hour,minutes:this.minute,seconds:this.second,meridian:this.meridian}}),this.place(),this.disableFocus&&this.$element.blur(),""===this.hour&&(this.defaultTime?this.setDefaultTime(this.defaultTime):this.setTime("0:0:0")),"modal"===this.template&&this.$widget.modal?this.$widget.modal("show").on("hidden",a.proxy(this.hideWidget,this)):this.isOpen===!1&&this.$widget.ad...

And the spec says that the fields have to be named like that. So `user-name` or `email` wouldn't work.

But don't worry, you can show it as you wish to your final users in the frontend.

And your database models can use any other names you want.

{* ../../docs_src/path_params/tutorial005_py310.py hl[16] *}

### Check the docs { #check-the-docs }

Because the available values for the *path parameter* are predefined, the interactive docs can show them nicely:

<img src="/img/tutorial/path-params/image03.png">

### Working with Python *enumerations* { #working-with-python-enumerations }

The value of the *path parameter* will be an *enumeration member*.

        int length = 32;

        Hexdump.hexdump(ps, data, offset, length);
        String output = baos.toString();

        assertNotNull(output);
        // Should start at offset 0 in display but show data from offset 16
        assertTrue(output.contains("00000:"));
        // First byte should be 0x10 (16 in decimal)
        assertTrue(output.contains(" 10 11 12"));
    }

    @Test

  override fun toString(): String = path.joinToString(separator = " / ")

  companion object {
    /**
     * A synthetic value that indicates there's no more bytes. Values with equivalent data may also
     * show up in ASN.1 streams to also indicate the end of SEQUENCE, SET or other constructed
     * value.

So, what we will do next is add the code to document how that *external API* should look like to receive the callback from *your API*.

That documentation will show up in the Swagger UI at `/docs` in your API, and it will let external developers know how to build the *external API*.

This example doesn't implement the callback itself (that could be just a line of code), only the documentation part.

                etc.

                It will be used for:

                * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                    show it as the response (JSON Schema).
                * Serialization: you could return an arbitrary object and the
                    `response_model` would be used to serialize that object into the
