Hi, I have an api call setup to create a payment link on the fly when a client is ready to make a payment. I seem to have everything setup correctly but I am unable to pre-populate the first and last name in the Contact section. The phone number and email address are populating as expected.
I have tried using the first_name and last_name options under pre_populated_data > buyer _address but that does not seem to work.
Does anyone know which values to use?
