This is the code we use to retrieve data via the web api (it's 2 separate functions as it promises and so the first one is a try catch handler and the second one does the heavy lifting. 


public async retrieveCRMRecords (entityName: string, query: string 😞 Promise<Xrm.RetrieveMultipleResult>{
        try {
        let result=await    this.getResults(entityName,query);
        return result;
        catch (error){
            // display error message within error section of tile
            return Promise.reject(error);
        finally {}

    public async getResults(entityName: string, query: string 😞 Promise<Xrm.RetrieveMultipleResult> {
        let a: Promise<Xrm.RetrieveMultipleResult>;
            return Xrm.WebApi.retrieveMultipleRecords(entityName,query).then(
            function success(result) {
            //  return result.entities;
             return result;
            function (error) {
                return Promise.reject(error);                
which we then call using
        let result= await this.retrieveCRMRecords("entityName",webapiQuery say"?$select=hdn_cssstyle,hdn_name&$filter=_hdn_template_value%20eq%20"+tId);
        result.entities.forEach(element => {
//do something with each record.
You should be able to repurpose the above to work without much difficulty but don't forget about CORS

Curious why didn't you used webAPI interface from PCF for this as opposed to direct XRM which is not supported PCF pattern ? Sample is published here  -


Please see -

private calculateAverageButtonOnClickHandler() : void

// Invoke the Web API RetrieveMultipleRecords method to calculate the aggregate value
this._context.webAPI.retrieveMultipleRecords(TSWebAPI._entityName, "?fetchXml=" + fetchXML).then
	function (response: ComponentFramework.WebApi.RetrieveMultipleResponse) 
		// Retrieve multiple completed successfully -- retrieve the averageValue 
		let averageVal:Number = response.entities[0].average_val;
		// Generate HTML to inject into the result div to showcase the result of the RetrieveMultiple Web API call
		let resultHTML: string = "Average value of " + TSWebAPI._currencyAttributeNameFriendlyName + " attribute for all " + TSWebAPI._entityName + " records: " + averageVal;
	function (errorResponse: any) 
		// Error handling code here

Hi @HemantG , 

Sorry for the late reply. Our requirement to call a 3rd party API via APIM. Yes if we had to query CRM we would definitely use the CRM web API.
