Hello,

I am using the Hubspot API and I managed to create a contact but when I try to add it to a list it returns this:

{

“status”: “error”,

“message”: “internal error”,

“correlationId”: “f331b738-b77b-4eae-a2ed-5cea1ea37c31”

}

I am using this request body:

{

“vids”: [

1608451

],

“emails”: []

}

Any idea what it could be?

(if anyone want to know, I am using postman to test the API and the hubspot list is active.)

Hey, @DanielHuelin 👋 Did you get this resolved? If not, can you make a request to this endpoint using your List ID, please? [https://legacydocs.hubspot.com/docs/methods/lists/get\_list](https://legacydocs.hubspot.com/docs/methods/lists/get_list)

And share the full response body here?

Thanks! — Jaycee

Hey, @DanielHuelin 👋 Thanks for doing that.

I see the issue. You are trying to use an Active List (note the “dynamic”: true that is part of the response body) It is not possible to manually add contacts to an active (dynamic) list.

You’ll need to create a static list if you want to manually add contacts to lists — in-app or via the List endpoints.

[Source](https://legacydocs.hubspot.com/docs/methods/lists/add_contact_to_list) — “Please note that you cannot manually add contacts to dynamic lists. To determine whether a list is dynamic or static, when you [get a list](https://legacydocs.hubspot.com/docs/methods/lists/get_list?hsLang=en), you will see a flag called `dynamic` that equates to true or false.”

Have fun building! — Jaycee
