# Example: Use Request and Collection Data as Query Parameters in a ProcessMaker Platform API Call

Learn how to reference Request data and Collection record data as parameters when calling a ProcessMaker Platform API endpoint.

## Overview

> [!NOTE]
> **Intended audience:** Process designers, Web designers, graphic designers, software developers, coding engineers
> 
> **Tags:** Collections; PMQL; Request Variable

In the example below, reference Request data and data from a specified r in the URL query to a ProcessMaker API endpoint. Determine dynamically the specific Collection record by including a PMQL query within a ProcessMaker Platform API call. The PMQL query uses a Request variable's value using mustache syntax for the Request variable's value in the URL to the API call.

Consider the following use case. Reference Collection data from Collection `5` for records created based on Requests started on a specific date. Determine the date dynamically by referencing a date in Request data stored in a [Request variable](/v1/docs/request-variable) `date`. The date that each Request starts is stored in another Request variable `date_work_start`.

1. [Log on](/v1/docs/participant-basics#log-on-to-processmaker-platform) to ProcessMaker Platform.
2. Open a new Web browser tab or window.
3. Connect to the API for your ProcessMaker Platform instance, such as`https://MyOrganization.processmaker.net/api/1.0`. For more information, see [Access ProcessMaker Platform RESTful API Documentation](https://docs.processmaker.com/apidocs).
4. Append to your URL the [Collections](/v1/docs/collections) syntax as desired such as `https://MyOrganization.processmaker.net/api/1.0/collections/5/records`.

In the URL above, `collections/5/records` calls for the records in Collection `5`.
5. Perform [PMQL](/v1/docs/search-using-processmaker-query-language-pmql) syntax as desired such as `https://MyOrganization.processmaker.net/api/1.0/collections/5/records?pmql=data.date_work_start`. Where `data` is calling the information of the collection records which specifically call information in the variable `date_work_start`.
6. Add a [Request variable](/v1/docs/request-variable) to your PMQL such as`https://MyOrganization.processmaker.net/api/1.0/collections/5/records?pmql=data.date_work_start="{{date}}"`, where the `{{date}}` is a comparison value that requires quotations marks.
7. Optionally, test your URL using a [Data Connector](/v1/docs/data-connectors) Endpoint.
