@sp-api-sdk/auth
Amazon Selling Partner API authentication package
Installing
npm install @sp-api-sdk/auth
Default values from the environment
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 |
Grantless APIs support
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: Object.values(AuthorizationScope),
});
const accessToken = await auth.getAccessToken();
Credentials caching
getAccessToken()
caches the access token for its whole duration, it will only request a new token if the current one has expired.
