**Problem Overview**

We are using **Celigo JavaScript API / API Builder** to create an API endpoint that receives an XML request from Postman and forwards the payload to a **Celigo Webhook Listener** to trigger an integration flow.

We noticed a major difference in behavior depending on payload conversion:

1. **XML --\> JSON Conversion:** When our Celigo JavaScript API script receives the XML payload, converts it to a JSON object (or JSON string), and posts it to the Celigo Webhook Listener endpoint, **the flow triggers successfully**.

2. **Raw XML directly:** When our Celigo JavaScript API script attempts to pass the **raw XML payload** directly to the Celigo Webhook Listener (without converting it to JSON), **the flow fails to trigger**.

### _ **Goal** _

We want to send an XML payload in Postman, process it through our **Celigo JavaScript API** , and forward the **raw XML string** directly to the Celigo Webhook Listener while ensuring the listener successfully parses/accepts the raw XML and triggers the target flow.

Hi @Shrehith_K1 On the listener, can you please open "Nonstandard request pattern" and check if the Override request media type is set to XML?

Thanks @kaustavroy

We already tried this, but no luck.

Hi @Shrehith_K1 could you please raise a support ticket so that we can look at the configuration?
