I’m currently testing a Webhook, but I’m encountering 500 errors.  
I have an API endpoint that successfully creates a contact:  
**Endpoint** : localhost:8080/core-api/hubspot-contact/create  
Request Body:  
{  
&nbsp;&nbsp;&nbsp;&nbsp;“firstName”: “test”,  
&nbsp;&nbsp;&nbsp;&nbsp;“lastName”: “test”,  
&nbsp;&nbsp;&nbsp;&nbsp;“email”: “[test2@gmail.com](mailto:test2@gmail.com)”,  
&nbsp;&nbsp;&nbsp;&nbsp;“phoneNumber”: “+911234567899”  
}  
Using this API, I’m able to save the contact details to HubSpot without any issues.  
However, the problem arises when I attempt to create a contact via the Webhook. While the Webhook is supposed to save the details in the database, it returns a 500 error.

Hey, @SSingh857 👋 Thanks for reaching out. It can be tough to trouble shoot issues that are happening in your local environment. I have some troubleshooting steps (organized with the help of our GPT tool) that may give our community members more info to help you track down the issue.

- Check Server Logs — Review logs for more details on what’s causing the 500 error
- Validate Request Payload — Verify the payload matches the expected structure. Compare the manual request (which works) with the webhook’s payload to spot any differences
- Test Locally with ngrok — Use ngrok to expose your local server to the webhook, then test using Postman to simulate the request
- Error Handling — Add error handling in your API to catch issues and return more robust status codes
- Database Check — Confirm database constraints, like unique values, aren’t causing issues when the webhook tries to save the data

Thanks for the additional information! — Jaycee

I am encountering a 500 Internal Server Error when trying to trigger a HubSpot webhook for the following endpoint:

[https://dev-api.xponentpowerapp.com/core-api/hubspot-contact/webhook](https://dev-api.xponentpowerapp.com/core-api/hubspot-contact/webhook)

However, when testing the same api using Swagger with the following JSON:  
{  
“eventId”: 2296615652,  
“subscriptionId”: 2849063,  
“portalId”: 47283995,  
“appId”: 3828294,  
“occurredAt”: 1728037175074,  
“subscriptionType”: “object.creation”,  
“attemptNumber”: 4,  
“objectId”: 64617102089,  
“objectTypeId”: “0-1”,  
“changeFlag”: “CREATED”,  
“changeSource”: “CRM\_UI”,  
“sourceId”: “userId:70535958”  
}  
it works as expected, without any issues.
