 - **Identify the `timezone`.** This may be tricky, a for example [Deutsche Bahn](https://en.wikipedia.org/wiki/Deutsche_Bahn) returns departures for Moscow as `+01:00` instead of `+03:00`.
 - **Copy the authentication** and other meta fields, namely `ver`, `ext`, `client` and `lang`.
 	- You can find these fields in the root of each request JSON. Check [a VBB request](https://gist.github.com/derhuerst/5fa86ed5aec63645e5ae37e23e555886#file-1-http-L13-L22) and [the corresponding VBB profile](https://github.com/public-transport/hafas-client/blob/6e61097687a37b60d53e767f2711466b80c5142c/p/vbb/index.js#L22-L29) for an example.

+	- Add a function `transformReqBody(ctx, body)` to your profile, which adds the fields to `body`.
 	- Some profiles have a `checksum` parameter (like [here](https://gist.github.com/derhuerst/2a735268bd82a0a6779633f15dceba33#file-journey-details-1-http-L1)) or two `mic` & `mac` parameters (like [here](https://gist.github.com/derhuerst/5fa86ed5aec63645e5ae37e23e555886#file-1-http-L1)). If you see one of them in your requests, jump to the [*Authentication* section of the `mgate.exe` docs](hafas-mgate-api.md#authentication). Unfortunately, this is necessary to get the profile working.
