How-to guides

Task-focused recipes for common Photon workflows. Each guide assumes you already have an API key — see Get API access.

• Relay an EVM transaction — build a submit-tx body, set gas overrides, submit async or sync, and check status.
• Relay a Solana transaction — relay SOL transfers and raw Solana instructions through the same submit endpoints.
• Register a webhook — receive signed HTTP callbacks on every transaction status change.
• Register a WebSocket — stream transaction status updates over a persistent connection.

For endpoint-by-endpoint request and response schemas, see the API reference.
