shopify.session.getCurrentId

Extracts the Shopify session id from the given request.

For embedded apps, shopify.session.getCurrentId will only be able to find a session id if you use authenticatedFetch from the @shopify/app-bridge-utils client-side package. This function behaves like a normal fetch call, but ensures the appropriate headers are set.

Learn more about making authenticated requests using App Bridge.

Example

app.get('/fetch-some-data', async (req, res) => {
  const sessionId = await shopify.session.getCurrentId({
    isOnline: true,
    rawRequest: req,
    rawResponse: res,
  });

  // use sessionId to retrieve session from app's session storage
  // getSessionFromStorage() must be provided by application
  const session = await getSessionFromStorage(sessionId);

  // Build a client and make requests with session.accessToken
  // See the REST, GraphQL, or Storefront API documentation for more information
});

Note: this method will rely on cookies for non-embedded apps, and the Authorization HTTP header for embedded apps using App Bridge session tokens, making all apps safe to use in modern browsers that block 3rd party cookies.
