You can use both Plaid Identity and Identity Match to return the name and contact information of the end user. However, which product to use depends on your use case:
Identity - /identity/get: This endpoint returns the name and contact information about the end user from their institution, however it does not allow you to input the identity information that the user entered on your app. Because of that, Plaid Identity cannot do a comparison - once you receive the information from /identity/get, you must compare the information using your own matching tool. This is useful for customers who already have their own method of identity matching, and do not need one from Plaid.
Identity Match - /identity/match: This endpoint returns the name and contact information about the end user from their institution, as well as a match score which indicates how well the provided identity data matches the identity information on file with the account holder's financial institution. To call /identity/match, you will need to provide a user object which contains the identity information that the user entered on your app. This endpoint is useful for customers who do not already have their own method of matching, and need a match score from Plaid.
