Trying to pass an invoice number from my form that processes payment through but need to know fields in, i.e. Customer Name, Invoice Number, etc. Can you create custom fields as well?

Re: Field Value Names

Hi @stevs102


The field you need to pass for invoice number is invoiceNumber which is inside order tag.


You can get the details about all the fields here : API Reference.

You can use the TryIt tab to test out the API request with the fields you wish to send.

Re: Field Value Names

You can send custom fields. If you use the createTransaction request as described in the reference guide: look for the field called "userFields".



Also, this is a good blog post about the appropriate use of these custom fields:
