Hi there everyone, I have a quick question about your react-sdk: How does the React SDK handle custom headers when calling the

/api/features/<sdk-key>

endpoint? We need to insert a

User-Agent

header from the client-side mobile app because our test environment blocks requests that lack this header.

Unfortunately, the React SDK doesn't support custom headers. As a workaround, you could fetch the payload yourself, and then pass the SDK payload into the GrowthBook init method. However, this approach means you lose some built-in features like auto-refresh and streaming updates

thanks for following up, @strong-mouse-55694! Do you have any implementation examples you could share?

Sure, it's pretty straightforward. You add those options to wherever you instantiate GrowthBook, like this:

const growthbook = new GrowthBook({
  apiHostRequestHeaders: {
    "header-name": "header-value",
  },
  streamingHostRequestHeaders: {
    "header-name": "header-value",
  },
  clientKey: "sdk-1234",
  // ...etc
});
