Webhooks are a new feature in VAT4U that makes it much easier to keep clients' systems in sync. They work hand-in-hand with the VAT4U API to allow real-time communication between VAT4U and other systems, so users don’t have to keep checking for updates manually.
What Are Webhooks?
Think of a webhook as a notification system for your software. When something important happens in VAT4U, like an expense being processed, VAT4U can automatically send a message to your system. Your system can then react immediately, keeping everything up-to-date without any extra work.
Before webhooks, you’d have to regularly check VAT4U via the API to see if anything changed. Now, VAT4U will reach out to you automatically whenever an event occurs.
Setting Up Webhooks
First, Go to Company Settings → API Configuration. You need to set up a Webhook URL — this is the address where VAT4U will send notifications:
Next, choose which events you want to be notified about, such as:
Company created or updated
Expense compliance check finished
Expense verification or Smart AI processing finished, etc:
VAT4U sends a notification to your system whenever one of those events happens.
Why It Matters
Webhooks, combined with the VAT4U API, allow for:
Automatic data synchronization between systems
Real-time notifications about updates and processing
Bidirectional data flow, so your systems are always up-to-date
