# Crowdsourcing Example

{% hint style="info" %}
Please read the [Quick Start](/implementation-guides/quick-start.md) guide to understand the basics of MRS first.
{% endhint %}

In order to call the /crowdsourcing endpoint, and report user feedback (see [Overview](/advanced-use-cases/crowdsourcing/overview.md)):

#### Required Fields

In the `/merchant/list` and `/merchant` endpoints, the `X-Request-Id` and `X-Timestamp` headers are returned. In order to submit a crowdsourcing request, you must store these values and send them in the `requestId` and `requestTimstamp` fields. If the report is in relation to a transaction in a `/merchant/list` request, you must also include the `transactionId` field of that transaction.

More on this in the OpenAPI spec.
