## Tasks

### Medium

**`webtask-medium.js`**: Generic task to fetch and reconstruct items from any medium publication.

Requires the Medium username appended at the end of the url:

```bash
http://localhost:8080/:medium_username

# when published on webtask.io
https://TASK_URL/TASK_NAME/:medium_username
```

### YouTube

**`webtask-youtube.js`**: Generic task to fetch and reconstruct items from any YouTube account. YouTube API key is provided via [secret environment variable](https://webtask.io/docs/issue_parameters) `YOUTUBE_API_KEY` setup in web editor of webtask.io.

* `/playlist/:playlistId`: returns all videos in the given playlist.
* `/channel/:channelId`: returns latest 10 videos in the given channel, sorted by date.

Construct your `GET` request urls like so:

```bash
http://localhost:8080/playlist/:youtube_playlist_id
http://localhost:8080/channel/:youtube_channel_id

# when published on webtask.io
https://TASK_URL/TASK_NAME/playlist/:youtube_playlist_id
https://TASK_URL/TASK_NAME/channel/:youtube_channel_id
```

**Response**

For all endpoints, response is reconstructed in the same format:

```json
[{
    "id": "8EMowpNlWPE",
    "title": "Fang Gong, Researcher - Bringing Privacy to Ocean Protocol",
    "description": "At Ocean Protocol, we unlock data for AI and use TCRs to maintain a registry of high-quality data sets through voting. Privacy is essential to protecting the ...",
    "imageUrl": "https://i.ytimg.com/vi/8EMowpNlWPE/mqdefault.jpg",
    "videoUrl": "https://www.youtube.com/watch?v=8EMowpNlWPE"
},
{
    ...
}]
```

If you want to get the original response returned from YouTube API, append `/raw` at the end of your request, e.g.:

```
https://TASK_URL/TASK_NAME/playlist/:youtube_playlist_id/raw
```

### Bounties

**`webtask-bounties.js`**: Task to fetch open bounties on Gitcoin and Bounties.network in one request. Task creates a unified response from fetching both networks.

Construct your `/` request url like so, e.g. locally:

```bash
http://localhost:8080/

# when published on webtask.io
https://TASK_URL/TASK_NAME/
```

**Response**

Response is structured by network and returns the count of open bounties:

```json
{
  "gitcoin": 1,
  "bountiesNetwork": 2
}
```

### MailChimp

**`webtask-mailchimp.js`**: Task to add a new newsletter subscriber.

Construct your `POST /newsletter` request url like so, e.g. locally:

```bash
http://localhost:8080/newsletter/jelly@mcjellyfish.com

# when published on webtask.io
https://TASK_URL/TASK_NAME/newsletter/jelly@mcjellyfish.com
```

**Response**

When subscription is successful:

```json
{ "status": "created" }
```

When subscriber already exists:

```json
{ "status": "exists" }
```

All errors from MailChimp (when `"status"` is a number) are simply passed through and follow the MailChimp API error responses, e.g.:

```json
{
  "type": "http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/",
  "title": "Forgotten Email Not Subscribed",
  "status": 400,
  "detail": "matthias@bigchaindb.com was permanently deleted and cannot be re-imported. The contact must re-subscribe to get back on the list.",
