# Request Payload Attributes

The upload API accepts a single binary payload representing the mobile application package. The file must be transmitted as multipart form-data and adhere to platform-specific size limits. This ensures secure, reliable ingestion of large mobile binaries during CI/CD or manual uploads. Only validated APK/IPA binaries are stored and made available for subsequent Test Plan executions.

| Attribute | Data Type | Max Length | Description             | Example         |
| --------- | --------- | ---------- | ----------------------- | --------------- |
| file      | binary    | 500 MB     | Mobile app binary (APK) | app-release.apk |
