Register Users for Challenges Without Coding

Hey all!

We recently ran a 30-day food tracking challenge where we invited our users to participate for a chance to win a personal Nutrition Masterclass with our Head Nutritionist and Head Chef. 

Since time was short (and when isn't it?!), we had to come up with a way to register users without building a landing page or needing any Dev resources at all. 

So we came up with the following flow!

1. Created a Content Card that had info about the challenge and we sent it to our target audience. We configured it so that when users clicked the card, it triggered a Custom Event called '30daychallengeUS_optedin'
   
   
   
2. Created an In-App Message which informed the user that they're successfully registered for the upcoming challenge. The IAM delivery was configured to be Action-Based, being triggered by the Custom Event that was just created by the card. 
   
   
   
3.  At the same time, the event triggered a Webhook campaign, which sent a call from Braze-to-Braze to create and write a new Custom Attribute against the user's profile that marked them as opted-in to the challenge. 
   
   

Note: Yeah, the content card could have created the attribute on click right away, but then we wouldn't be able to trigger the confirmation message :))

The flow worked seamlessly and we're happy to say we got thousands of users joining the challenge!
