# Create a build certificate

To complete the uploading process and view your files on the Code Signing tab of your app, continue with the [POST /apps/{app-slug}/build-certificates/{build-certificate-slug}/uploaded](https://api-docs.bitrise.io/#/build-certificate/build-certificate-confirm) endpoint.
