# Issuer API ## Description The Issuer API is a [NestJS](https://nestjs.com/) package that provides restful endpoints for handling Certificate operations (certificate request, issuance, transfer, claiming, revoking). It is is a component of [Energy Web Origin's](https://energy-web-foundation-origin.readthedocs-hosted.com/en/latest/) Traceability SDK. ## Documentation - [Issuer API](https://energy-web-foundation-origin.readthedocs-hosted.com/en/latest/traceability/packages/issuer-api/) - [Traceability SDK](https://energy-web-foundation-origin.readthedocs-hosted.com/en/latest/traceability/) ## Contributing Guidelines See [contributing.md](../../../contributing.md) # Energy Web Decentralized Operating System EW-Origin is a component of the Energy Web Decentralized Operating System (EW-DOS). The purpose of EW-DOS is to develop and deploy an open and decentralized digital operating system for the energy sector in support of a low-carbon, customer-centric energy future. We develop blockchain technology, full-stack applications and middleware packages that facilitate participation of Distributed Energy Resources on the grid and create open market places for transparent and efficient renewable energy trading. - To learn about more about the EW-DOS tech stack, see our [documentation](https://app.gitbook.com/@energy-web-foundation/s/energy-web/) For a deep-dive into the motivation and methodology behind our technical solutions, read our White Papers: - [Energy Web White Paper on Vision and Purpose](https://www.energyweb.org/reports/EWDOS-Vision-Purpose/) - [Energy Web White Paper on Technology Detail](https://www.energyweb.org/wp-content/uploads/2020/06/EnergyWeb-EWDOS-PART2-TechnologyDetail-202006-vFinal.pdf) ## Connect with Energy Web - [Twitter](https://twitter.com/energywebx) - [Discord](https://discord.com/channels/706103009205288990/843970822254362664) - [Telegram](https://t.me/energyweb) ## License This project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details ## Notes If you decide to use CertificationRequest, then you should also include `ScheduleModule.forRoot()` in your application, to run synchronization task. ## Signer configuration IssuerApi module by default encrypts supplied platform operator private key using database storage, and `OPERATOR_ENCRYPTION_KEY` environment variable as encryption key for the storage. If you want to use another signer, make sure to create `SignerAdapter` provider, that implements `SignerAdapter` abstract class. This provider can be registered anywhere: ```ts import { SignerAdapter } from '@energyweb/issuer-api`; class MyCustomSigner implements SignerAdapter { // ... } const signerAdapter = { provide: SignerAdapter, useClass: MyCustomSigner, }; @Module({ providers: [signerAdapter], imports: [IssuerApi.register()] }) ``` For migration instructions see changelog. --- _Source: https://npm.io/package/@energyweb/issuer-api · Machine-readable twin of the npm.io package page.
