Hi there! I have been trying to create event types for the timeline, however, I’ve been getting a 500 response every time I make a request! Here is the **request** I am making: _POST URL_ **:** [https://api.hubapi.com/integrations/v1/6256213/timeline/event-types?hapikey={hapikey}&application-id=6256213&userId=Brock%20Jenken](https://api.hubapi.com/integrations/v1/6256213/timeline/event-types?hapikey=%7Bhapikey%7D&application-id=6256213&userId=Brock%20Jenken) _({hapikey} is a placeholder here for the real key)_ _Header_ **:** {“Content-Type”: “application/json”} _Body_ **:** { “name”: “session”,     “applicationId”: “6256213”,     “objectType”: “CONTACT”,     “headerTemplate”: "Attended ",     “detailTemplate”: “Session occurred at” } From that request I get this **response** : _Status Code_: 500 _Body_: { “status”: “error”, “message”: “internal error”, “correlationId”: “f2fe8bee-52d2-4802-a0ab-1f2a90d13065”, “requestId”: “e417a4ba2f2470799ad8973cdf166993” } Any help would be greatly appreciated, and I thank you in advance! ---

Hi @BrockJenken, When looking to create the timeline event type using this endpoint documented [here](https://developers.hubspot.com/docs/methods/timeline/create-event-type): The POST url should include the _userId_ as well. As an example of the POST request url that I sent through: `https://api.hubspot.com/integrations/v1/197994/timeline/event-types?hapikey={{hapikey}}&userId={{user_id}}` With this POST body ```auto { "name": "session", "applicationId": "197994", "objectType": "CONTACT", "headerTemplate": "Attended ", "detailTemplate": "Session occurred at" } ``` And I’m able to see that the _session_ event got created just fine in my dev portal: ![session_event.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/c/1/c13ac42ec4d10bc11659f4414eddee1e7e43247b.png) Additionally, one thing to note: You do not have to include the application-id as a parameter at the back of the url as you’ve already included it on the url as such /v1/6256213. Could you try this out and let me know if you’re still seeing the 500 internal error? ---

Hi Wendy, Thank you for getting back to me! I tried removing the _application-id_ from the URL, but I am still getting the same issue. My original eURL does include the _userId_ parameter, but I am wondering if the value is correct. I have it curently as the username present beside my hapikey in the page to access the hapikey. Here is the 500 error that was returned: { “status”: “error”, “message”: “internal error”, “correlationId”: “c987dd68-5a35-4557-b8dc-b9466ce2cd5d”, “requestId”: “e5f150215e4b5354acb68d4fe0cebd7f” } Thank you for your help! ---

Hi @BrockJenken, Thanks for testing that out. In this case, do you mind sharing with me the following: - Your dev portal id - Your application id So that I can further test thing out on my end to see if I’m encountering any 500 errors. ---

Of course! My dev portal id is 6211335 and my application id is 6256213. Thank you so much! ---

Hi @BrockJenken, Thank you for sharing that across with me! When taking a look into your dev portal _6211335_ I noticed that the “application id” is a test accounts hub ID (under the _Testing_ tab) and not an application id (under the _Apps_ tab) The prerequisites for using the [Timeline API](https://developers.hubspot.com/docs/methods/timeline/timeline-overview) is stated here: [Integration Platform API Prerequisites](https://developers.hubspot.com/docs/faq/integration-platform-api-requirements) where you would need to create an app in HubSpot: [How do I create an app in HubSpot?](https://developers.hubspot.com/docs/faq/how-do-i-create-an-app-in-hubspot) Simply put, the application id here when creating timeline event type is referring to this app id: ![app id.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/7/e/7e415ba5f5d1d1ea190a1d717c714031aa703d11.png) and not the Test portal Hub ID. You can learn more about the usage of the test account here: [Test accounts](https://developers.hubspot.com/docs/faq/how-do-i-create-a-test-account). ---
