Hi all, I’ve been working on an API and I have some difficulties with using the post option with a list. The problem is that I get a 500 error when trying to make it in Triggre, but it’s the same as in postman and in postman it does work. I have a suspisicion that it has to do with the list i’m using. ![image](https://canada1.discourse-cdn.com/flex035/uploads/triggre/original/1X/50da6c591adc3c7fdbd6b6735666d9cdc609a01a.png) ![image](https://canada1.discourse-cdn.com/flex035/uploads/triggre/original/1X/da23fb916a6229ee518e50ffa7dc7e8111e10c18.png) Does somebody know what I’m doing wrong here? ---

Unfortunately you currently can’t retrieve the content of the response when there’s a 500-error. We’ve put this on our backlog to create. ---

If you get a 500 error from the other side (not the Triggre side), it is not related to the data you receive. It is likely the data you send that has a mistake. Can you post what data you send to the other API? Also please note this post, which ran into a similar problem: [https://community.triggre.com/t/json-response-post-api/](https://community.triggre.com/t/json-response-post-api/) ---

Can you send me the name of the sub domain of your application by PersonalMessage, so i can investigate your design? ---

Hi Lode, It seems salesInvoiceLines is empty. In the upcoming weeks we’re going to post a TriggreWeekendMasterClass with a nice trick how to use Zapier to check what you’re actually sending in your message. To give you a small hint: Create a Raw WebHook in Zapier and change the URL in your application to that WebHook URL. Send the Raw body to yourself via email. ---
