My request body:
Thank you for your question, @cbinton. An agent will get back to you as soon as possible. In the meantime, if any community member knows the solution, please reply here. -Jenn
Thanks for your patience.
The FX Rate API is intended to be used for Visa Direct Original Credit Transactions, so the rates are associated with this type of transaction, meaning it's not for purchase. The FX calculator is used for purchase rates.
Hope this clarifies things!
