Coinbase Pay SDK FAQ

As a developer, how do I onboard to Coinbase Pay?

Onboarding to Coinbase Pay is not yet self-serve. To be added to the Coinbase Pay allowlist, please:

  1. Fill out the Coinbase Cloud Interest Form at https://www.coinbase.com/cloud/cloud-interest.

Can the Coinbase Pay widget open in a new tab or as a modal?

Yes, you can configure it to either. The default functionality embeds the Coinbase Pay widget when the user is logged in and logged out. To open it in a new tab or popup window, configure the initOnRamp parameters, experienceLoggedIn and experienceLoggedOut, to new_tab or popup.

Can I embed the Coinbase Pay widget inside my platform (versus the user seeing a modal/new tab)?

The Coinbase Pay widget can be embedded on approved domains (and is the default setting). To embed the widget, configure the initOnRamp parameters, experienceLoggedIn and experienceLoggedOut, to embedded.

๐Ÿ‘

Coinbase recommends using a mix of experienceLoggedIn: โ€œembeddedโ€ and experienceLoggedOut: โ€œpopupโ€ for a more seamless experience. For Chrome extensions, the logged out embedded experience opens a popup window (to login), and the extension popup may close, losing the window reference.

What fees do you charge?

The following fees are applicable for Coinbase Pay:

  • Spread: Coinbase Pay includes a spread in the price when you buy cryptocurrencies. This allows us to temporarily lock in a price for trade execution while you review the transaction details prior to submitting your transaction.

  • Coinbase fees: Fees are calculated at the time you place your order and may be determined by a combination of factors, including the selected payment method, the size of the order, and market conditions such as volatility and liquidity. Fees are listed in the order preview screen before you submit your transaction and may differ for similar transactions.

๐Ÿ“˜

Coinbase does not charge any Coinbase fees when a user moves their existing crypto balance from their Coinbase Account to a self-custody wallet/dapp using Coinbase Pay.

  • Network fees: For transactions on cryptocurrency networks (i.e., transfers of cryptocurrency off the Coinbase platform), Coinbase incurs and pays network transaction fees (e.g., minerโ€™s fees). We charge a fee based on our estimate of these network fees. In some cases, the final fee that Coinbase pays may differ from the estimated fee. All fees we charge are disclosed at the time of transaction.

๐Ÿ“˜

Coinbase does not receive any portion of the network fees that we charge.

Can we customize the email sent to the users?

No. Users that make a purchase via Coinbase Pay receive the standard emails that they receive when purchasing and sending crypto from their coinbase.com account to a self-custody wallet. We will add the ability to update emails at a later date.
