Profiles are used for Paychex to shape certain responses and for versioning. Paychex uses vendor media type profiles format. These are used in the headers of the request to allow an endpoint to have different responses based on the profile being requested. To specify a vendor media type profile, you’ll need to send it within the request header using the "Accept" key with the value of the profile. However, each resource has a default vendor media type profile, so they are not required when making calls.

All our vendor media types are defined in our Open API document references so you can see the data elements in the request and response for details.

Example: application/vnd.paychex.association_companies.v1+json
