Hello I need to use the API to create timeline events for contacts. For this I figured I need to create a public app. I’m having an issue to authenticate it.
This is the message I get when trying to:

Support helped me to track the following error:
{status: “error”,…}
- correlationId: “1d6a8f46-7db9-4187-b3f8-2ce247fb54fd”
- message: “Invalid input JSON on line 1, column 103: Cannot deserialize value of type `java.lang.String` from Array value (token `JsonToken.START_ARRAY`)”
- status: “error”
But it was as far as they could get.
Can anyone help me with this, and let me know also if this is being an impediment for using the API?
The thing seems I’m not being able to successfully create is the client when using:
client = hubspot.Client.create(access_token=“”) I’m missing the access token, and I think it is when I verify it that I get it.
Thanks!
