When a user creates data with a POST request, I want to redirect them to the URL of the new thing they created – but for that I need to know the URL that it was accessed with.

I have a database of events that I want to react to when they happen, but the change feed doesn’t include the actual document that was added – but you can add one of the built-in functions to a sequence to make that happen. This post will show how to achieve this by wiring up a built-in action to fetch the document with another action of our own that then handles the data. Continue reading →

I included an example of a serverless endpoint to receive incoming webhooks in my talk at PHPUK last week and I got a few questions about it so I thought I’d share that example in written form. Continue reading →
