SDK how-to guides
Solve a specific integration task with the Core SDK.
These guides assume you can already create a client and focus on one outcome at a time. If you have not created a client yet, complete the first-client tutorial.
Authenticate with email OTP
Request a one-time code, verify it, and work with the resulting session.
Choose Account readiness
Decide whether your application needs no Account, a receivable Account, or a deployed Account.
Run the client in Node
Own one client in a service, script, CLI, or agent process.
Observe SDK failures
Send bounded failure events to the analytics client your host already owns.
Create a payment
Submit a personal-Account payment and understand the current settlement boundary.
For exact method inputs and return types, use the API reference. For a plain-language view of what is available, limited, or unavailable, use capability status.
