How to fetch Save for later pages in SPFx Web part.

Hi,

I found the way. here is the code snippet:

private async _getApiToken() : Promise<string> {
const siteCollectionUrl = this.props.context.pageContext.web.absoluteUrl;
const restQuery = `${siteCollectionUrl}/_api/sphomeservice/context?$expand=Token`;
const httpClientOptions: ISPHttpClientOptions = {};
const response: SPHttpClientResponse = await this.props.context.spHttpClient.fetch(restQuery, SPHttpClient.configurations.v1, httpClientOptions);
const responseJson: any = await response.json();
return responseJson.Token.access_token;
// Improvement: Grab the Hub api URL from: responseJson.Urls
}

private async _getsavedForLaterPages(): Promise<void> {
const isHubSite = await this._isHubSite();

if (!isHubSite) return;
const token = await this._getApiToken();
const restQuery = `https://{region}-sphomep.svc.ms/api/v1/documents/saveForLater?start=0&count=100`;
const httpClientOptions: IHttpClientOptions = {
headers: {
'authorization': `Bearer ${token}`,
'sphome-apicontext': `{"PortalUrl":"${this.props.context.pageContext.site.absoluteUrl}"}`
}
};
const response: HttpClientResponse = await this.props.context.httpClient.fetch(restQuery, SPHttpClient.configurations.v1, httpClientOptions);
const responseJson: any = await response.json();
console.log("Saved for later data:"+responseJson);
}

Thank You,
