@DGrant5 - I think you may be missing the ‘inputs’ JSON array element on the structure here. My read is that the structure should be:

```lia-code-sample
{
 "inputs": [
 {
 "from": {
 "id": "string"
 },
 "to": [
 {
 "id": "string"
 }
 ]
 }
 ]
}

```

Best of luck!

Steve

Hi @DGrant5

here is the curl to delete the association between 2 objects.

```lia-code-sample
curl --request POST \
 --url https://api.hubapi.com/crm/v4/associations/fromObjectType/toObjectType/batch/labels/archive \
 --header 'authorization: Bearer YOUR_ACCESS_TOKEN' \
 --header 'content-type: application/json' \
 --data '{
 "inputs": [
 {
 "types": [
 {
 "associationCategory": "HUBSPOT_DEFINED",
 "associationTypeId": 0
 }
 ],
 "from": {
 "id": "string"
 },
 "to": {
 "id": "string"
 }
 }
 ]
}' 

```
