Common Questions: How do I evaluate the details provided in the TC String?

How do I evaluate the details provided in the TC String?

The TC String includes four (4) segments of information: the core string, publisher restrictions, publisher-approved vendors, and out-of-band (OOB) signaling. The technical specs describing the TC String provide details on specific information provided in each segment. These details may change from the start of the transaction to the end of the transaction. Vendors must evaluate the four segments of a string as it relates to a given transaction, determine the intent of the information provided, and proceed accordingly.
