# Passthrough APIs

Passthrough APIs allow you to forward requests from the Frends API endpoints to your system's provided APIs, in the case where data conversion or other logic is not needed. They are excellent to use to keep a coherence in your API branding, having all used endpoints within the same domain, without requiring much configuration or overhead from creating a Process in between where nothing really happens.

To configure a passthrough API, you need to have created an API to Frends, and then click **Create passthrough API** button in API management view. In the passthrough API editor, you can specify the target url for each API endpoint, optionally passing along parts of the original request's url or query parameters, as well as manage the headers used in the passthrough.

You can also create an **All endpoints** passthrough, which will always pass on the final part of the request path and query parameters to the target API without having all possible endpoints defined in the API specification. The original url and path are replaced with the target system's url and path.&#x20;
