HumbleBundleBot

Scrapes HumbleBundle.com for new Bundles and posts new bundles to different webhooks whenever a new Bundle shows up. Each Bundle can be sent to a different webhook, allowing easy organization of messages - in Discord, each channel can have webhooks associated with them for integrations like this.

Scraping is done once and results are sent to all relevant webhooks using Serverless Functions and Azure Queue, making the system extremely cheap to run and highly scalable.

Changelog

7/15/2020 - You can now register for subtypes of BOOKS, such as RPG and COMIC

3/13/2019 - Thanks to BallBrian, we now have a nice blazor powered registration site! Check it out here: https://humblebundlenotificationssite.azurewebsites.net

1/8/2019 - In response to popular demand, you can now optionally register a Humble Bundle Partner referral that will be attached to all messages for your webhook only. This means that if you're a streamer who runs your own Discord and want your audience to be able to throw some of their purchase money at you, you can signup with Humble Bundle and register your partner name here to make it happen!

Not a Partner and want to support me for developing this service? Use cswendrowski for the Partner value when signing up, as the example will show. Thank you!

11/8/2018 - You can now opt-in to Developer Messages - we will only send these out in case of major outages to indicate when the Bot is down for maintenance and when it is back up. This message type is currently only valid for Discord webhooks.

5/23/2018 - We now support the ability to register any webhook instead of just Discord webhooks. If you register a Discord webhook the experience is still the same and you will receive Discord formatted messages. If you have already registered a webhook before this date, your webhook registration has been defaulted to Discord.

If you register a webhook of type RawJson (1), you will receive a BundleQueue payload that looks similiar to the following:
