How to perform a merchant initiated transaction (MIT) against a network tokenized card

ucjonathan — Thu, 04 Dec 2025 16:02:58 GMT

I'm going to ask this question again because it's been a month with no answer here or on StackOverflow. Does anyone know what the request looks like to charge a tokenized card in a merchant initiated transaction (MIT) context? They have the following documentation which works for a customer initiated transaction (CIT) against a network tokenized card. I need to understand the fields that need to be populated on the request.

https://developer.authorize.net/api/reference/index.html#payment-transactions-charge-a-tokenized-cre...

Any information on how this is supposed to be accomplished would be greatly appreciated.

For a merchant initiated transaction with a tokenized card, use the standard tokenized charge request and set it as MIT by including the transactionRequestType and any required MIT or recurring flags.

@Elio Can you share an example JSON payload? I need more specifics on what "any required MIT or recurring flags" should be implemented. I really wish that Authorize.Net documentation was clear with an example of the MIT similar to what they provide on the CIT.
