Add custom data to your Fintoc Objects
Some Fintoc objects (currently Charges, Checkout Sessions, Payment Links, Payment Intents, Transfers and Account Numbers) have a Metadata parameter. You can use this parameter to add custom key-value pairs to them.
Metadata is useful to hold arbitrary structured data of the objects you interact with. This can help ease the integration of your system with Fintoc. As an example, you could store your user's full name and corresponding unique identifier from your system on a Fintoc Payment Intent object. Metadata is not used or modified by Fintoc in any way.
Limitations
Metadata can hold up to 50 keys, with names up to 40 characters of length and values up to 500 characters long. Only strings, boolean and numbers are permitted as metadata values.
