What is Pabbly Hook?

Pabbly Hook is a webhook handling and webhook forwarding application.
In simple terms, it can handle incoming webhooks at scale and can forward it to any destination. The destination can be Pabbly Connect, Zapier or any other integration platforms.
While forwarding to destination, you can control the rate limit at which you want to forward the webhooks.
You can also modify / filter the webhooks on fly before forwarding it to the destinations.
Let me give you an example and it will make it easier to understand:

1. Nowadays most of the applications come with native webhooks. Webhooks eventually will become the de-facto standard for sending event data across applications.
2. Through webhooks, different events that happen in the applications are sent to external destination applications.
3. For example, In the case of an email marketing application, on each email being opened by different recipient, a webhook event may trigger with all the data inside it.
4. Lets say, these events are happening at a rapid speed and if you capture these events and send it to Google Sheets. Google Sheets might not accept all the webhook due to their own rate limit setting. Sometimes, some data might not be handled due to the same rate limit setting.
5. With Pabbly Hook, you accept all these rapid incoming webhooks at Pabbly Hook end and then you setup a rate limit setting that only forward 10 webhooks every minute to the destination.
6. This destination can be an integration platform like Pabbly Connect or any integration platform. Once the destination receives the rate limited webhooks, it can then send it to apps like Google Sheets at a controlled speed.
7. It can also modify the incoming webhooks at fly. It can also filter the webhooks at it's end before the webhooks are forwarded to the destination.
8. Pabbly Hooks is built on top of Apache Kafka/Pulsar so it scales for millions of webhooks and it also has an auto retry mechanism built-in incase the destination is not available or is down at the moment.
