Server SDK changelogs

TypeScript SDK changelog

July 27, 2026

v1.1.0

Added OAuth2 client-credentials support. Pass bearerAuth: { clientId, clientSecret } and the SDK handles the token exchange and refresh automatically:

const client = new PayabliClient({
    bearerAuth: {
        clientId: "...",
        clientSecret: "...",
    },
    environment: PayabliEnvironment.Sandbox,
});

See the TypeScript SDK guide and Authentication to compare both methods.

Breaking change: API key auth now requires the apiKeyAuth wrapper

Supporting OAuth alongside API key auth required restructuring the constructor’s auth options. The top-level apiKey field no longer exists — wrap it in apiKeyAuth:

// Before
const client = new PayabliClient({
    apiKey: "...",
    environment: PayabliEnvironment.Sandbox,
});
// After
const client = new PayabliClient({
    apiKeyAuth: {
        apiKey: "...",
    },
    environment: PayabliEnvironment.Sandbox,
});

Existing integrations using the old flat apiKey field need to update to this shape.
