Paychex connects with OAuth 2.0 client credentials: the API key and secret of an application in Paychex Flex.

## Install the Paychex integration

Install Paychex from [Available integrations](https://app.truto.one/integrations/available/d43e8aca-2f47-438d-b494-d78bb18ea536) in each environment you connect accounts from.

## Create API credentials

1. In Paychex Flex, go to **Company Settings** → **Connected Applications**.
2. Create an application. Paychex Flex generates an API key and secret for it.
3. Copy both. Treat the secret like a password.

See Paychex's [Authentication](https://developer.paychex.com/resources/authentication) docs.
