# ProPresenter-API

## 7.9 UPDATE & PUBLIC API

The upcoming 7.9 release of ProPresenter will include an officially supported public API.

The official documentation page is here:

https://renewedvision.com/propresenter/api/

The full auto-generated Swagger HTML is a bit easier to navigate, and it is here:

https://renewedvision.com/api_spec/index.html

And, the actual source OPENAPI spec document (JS) is here:

https://renewedvision.com/api_spec/swagger.json

But I'm mirroring it here as a formatted JSON document too.

[pro7.9.openapi-spec.json](https://github.com/jeffmikels/ProPresenter-API/blob/master/pro7.9.openapi-spec.json)

## CHANGES

Recently, I have begun to migrate all the documentation into machine-readable formats
so that as the Pro7 API improves, we will be able to more readily track the changes.

It is also my hope that this effort will inspire RenewedVision to join the documentation
effort directly.

## API METHODOLOGY

AsyncAPI is a great system for defining APIs and for generating code and documentation, but editing it by hand
seemed cumbersome to me, so I built my own solution.

1. I converted our former Markdown documentation files into a `api.yaml` format that is inspired by AsyncAPI, but is more easily edited.
2. I wrote a Python script to automatically convert my `api.yaml` files into AsyncAPI 2.1.0 files.
3. I use the AsyncAPI command line generator commands to render out html files.

## API.YAML SPECIFICATIONS

The `api.yaml` file begins with a section called `asyncapi`. That section may contain anything an AsyncAPI `2.1.0` file may contain.

Then, there is a `types` section that holds defined data types similar to the way AsyncAPI does schemas. These will be translated into AsyncAPI schema nodes.

Types are structured as follows:

```yaml
typename:
  type: |-
    can be a built-in type like

`integer`, `string`, `number`, `list`, `list[othertype]`, or `object`

or it can be another defined type or list[othertype]
  parameters:
    field_1:
      type: typename
    field_2: constantvalue
    field_3:
      type: typename
      options: [option1, option2, option3]
      description: "each field can have a description"
      examples: ["each field can have an example"]
  example:
    field_1: an arbitrary value
    field_2: constantvalue
    field_3: option1
```

Then, there is the `channels` section which defines the main application message endpoints. ProPresenter exposes two channels, `/remote` and `/stagedisplay`.

Each `channel` is structured as follows:

```yaml
channels:
  channelname:
    summary: Simple name for this channel
    description: |
      Block markdown content describing this channel in detail
      actions: "list of actions, see below"
```

Each `channel` has a list of `actions` that can be sent or received.

Actions may contain a `message` and or `response` and are structured as follows (NOTE: `payload` and `example` follow the same structure as a type, and the `example` must match the payload structure):

```yaml
actionName:
  summary: simple name for this action
  description: markdown text describing this action
  message:
    payload:
      action: actionName
      field_2: someConstantValue
      field_3:
        type: string
        options: ["1", "2", "3"]
        example: "2"
        description: textual description
    example:
  response:
    payload:
    example:
```

# CONTRIBUTING

To contribute, please just edit the `api.yaml` file. I will regenerate the other documentation myself until I get Github actions working.
