# Plaid Integration

## Overview

Knot has a partnership with Plaid, described in Plaid's documentation [here](https://plaid.com/partner-directory/). This partnership allows Knot to use Plaid's `processor_token` functionality to retrieve transaction data from Plaid for the purpose of detecting merchants where users are spending. Doing so can help improve conversion.

By creating a `processor_token` through Plaid's API and providing that to Knot when you create a session to initialize the Knot SDK, merchants where the end user is spending will be automatically detected and modified to be more prominent in the user experience. This will in turn help improve conversion for your product experience. Please note that this process takes a number of seconds, so users will not immediately see a modified list of merchants when the SDK is initialized - rather after a number of seconds while on the merchant list screen, if returning to the screen after authenticating to a merchant, or if returning on subsequent sessions.
