Advanced tools
@sp-api-sdk/auth
Amazon Selling Partner API authentication package
npm install @sp-api-sdk/auth
These constructor options can be passed using environment variables:
Property Name | Environement variable |
---|---|
clientId | LWA_CLIENT_ID |
clientSecret | LWA_CLIENT_SECRET |
refreshToken | LWA_REFRESH_TOKEN |
Some APIs require grantless authentication, which is done by passing scopes, instead of a refresh token.
The available scopes are exposed in the AuthorizationScope
enum from this library.
import { SellingPartnerApiAuth, AuthorizationScope } from "@sp-api-sdk/auth";
import { AuthorizationApiClient } from "@sp-api-sdk/authorization-api-v1";
const auth = new SellingPartnerApiAuth({
clientId: "",
clientSecret: "",
scopes: [AuthorizationScope.NOTIFICATIONS, AuthorizationScope.CLIENT_CREDENTIAL_ROTATION], // Or choose the only ones you need
});
const accessToken = await auth.getAccessToken();
getAccessToken()
caches the access token in memory for its whole duration, it will only request a new token if the current one has expired.
You can subclass SellingPartnerApiAuth
to add custom logic, for example, caching the access token in a store.
import { SellingPartnerApiAuth } from "@sp-api-sdk/auth";
import { storeToken, getToken } from "./token-store";
class StoredSellingPartnerApiAuth extends SellingPartnerApiAuth {
async getAccessToken() {
let token = await getToken();
if (token) {
return token;
}
token = await super.getAccessToken();
await storeToken(token, { ttl: this.accessTokenExpiration });
return token;
}
}
