Flows define a group of integrations that your customers can connect to. There are three types of flows that you can enable in hotglue:

​
V1 - One-way flows

​
Source flow

This is the simplest way to use hotglue, and the default flow type when you toggle off bidirectional flows. With a source flow, your customer connects the source or tap, and you read data in from those linked sources into your own default target.

​
Target flow

This can be enabled in the General tab of a V1 flow. This is the inverse of a source flow, where your customer links an integration that you write data out to, but cannot read data in from.

​
V2 - bidirectional flows

If you need to read and write data to the same integration, you can use a bidirectional flow to use the same connection for both. There are two main differences between API calls for V1 and V2 flows:
  • V2 flows include a /v2 in API calls.
  • V2 flows do not have a concept of taps and targets. From the perspective of a V2 flow, everything is a connector.
