Questions

Answers

Q1: How do I know which countries / payment methods / fiat currencies / tokens can be used for a crypto transaction?

A: Use Meld's service provider properties endpoints to find this information. You can pass in a particular onramp or set of onramps, or use the query param accountFilter=true to only return back data for the onramps your account has enabled.

Q2: What is the difference between Meld's Widget and Wizard? Which should I use?

A: You can find more information on this subject here. There are 2 parts of a transaction, gathering the details of the transaction (such as how much crypto to buy, which token, which wallet address etc) and actually executing the transaction. Meld's wizard has a UI that handles both parts. Meld's widget handles only the second part, so if you use it you will have to use your own UI to gather the details of the transaction.

Q3: Should I poll or use webhooks to get transaction status updates?

A: You should use webhooks, they have much lower latency and are less of a strain on your infrastructure. Meld highly recommends using webhooks over polling, but having an infrequent (every 6 hours or more) poller as a backup to webhooks is fine. Read more about this here.

Q4: A user is having an issue with a transaction, who should I reach out to for customer support? Meld or the onramp?

A: You can always reach out to Meld as the first line of defense for customer support. If there's an issue with the UI, or a failing API call, or a transaction that occured that you don't see returned by Meld's system, Meld will be happy to help. However, if the user paid but didn't receive their crypto, Meld will direct your query to the onramp, so in such a scenario feel free to reach out to the onramp directly as Meld doesn't touch the flow of money or crypto.

Q5: Do I have to fetch and store transaction information from Meld?

A: Regardless of whether you are using Meld's white label widget experience or all in one wizard, whether you want to fetch and store transaction data is your choice. You can find your transactions in the Meld dashboard and can always simply export them from there. See here for more details.
