# Adding a Request Payload

The second part of the job submission request is a file upload with name payload. This is expected to be a zip file, with a filename ending in `.zip`.

## Payload for Solver Job

The supported contents of this zip file are:

- Required unless supplied by a dependency: A problem in `LP/MPS` or `Save` file format with corresponding extension (`.lp`, `.mps`, `.svf`) which will be loaded by the solver with the `XPRSreadprob` or `XPRSrestore` routine as applicable.
- Optional: A basis file with the same filename as the problem file and extension `.bas`. If present in the zip it will be loaded by the solver with the `XPRSreadbasis` routine after the problem is loaded and prior to solving.
