Our API infrastructure utilizes consistent terminology and labeling

Authorization

With each API call you need to include a validate OAuth 2.0 access bearer token. You retrieve an access bearer token by using the Authorization Service using your API key and secret. When making the calls to the APIs the bearer token needs to be included either within the header or within the request as a parameter.

Parameter Example:

https://api.paychex.com/companies?access_token={bearer_token}
Header Example:

Authorization: Bearer {bearer_token}
