New guides on error handling and detecting changes

// By Taylor Krusen • May 29, 2020

When building with the Dropbox API, there are two common needs that you may encounter: dealing with errors and learning about changes in Dropbox. We just published new developer guides for both topics!  

Introducing the Error Handling Guide and the Detecting Changes Guide.

Handling errors in Dropbox

Something you expect to find in well-written code is proper exception handling. The art of predicting, detecting, and gracefully recovering from errors is essential to building quality applications, especially when they integrate with other systems. In the Error Handling Guide, we cover error types, scenarios where you may encounter them, and share some best practices around error handling. In addition to the new guide, there are two other surfaces you can find information about errors in the Dropbox API:

Error section under each endpoint in the Dropbox http reference docs
Error section under /sharing/get_shared_link_metadata

Detecting changes to Dropbox data

Pretend you created a fictional app named DropPalette that analyzes photographs and returns a color palette with the five most common colors. The experience you want for your users is that photos dragged into the DropPalette folder are automatically analyzed and saved back with a color palette. You could provide that experience using webhooks. 

Reacting to changes in Dropbox is a common need for a broad spectrum of apps. Because the Dropbox API provides multiple mechanisms to accomplish that, you’ll need to pick the approach best suited to the needs of your specific app. In the Detecting Changes Guide, we cover webhooks, polling, and efficient use of cursors to request the latest data. We provide some context around each tool and provide some guidance on choosing the right one for your app.  

Keep an eye out for additional developer guides over the next couple of months!
