ASSOCIATIONS ENDPOINT

when using the api : POST-https://api.hubapi.com/crm/v4/associations/0-1/0-2/batch/read

Getting the error

"status": "error"

Can someone please help me and provide details on how to use the associations end point to get associations between deals and contacts and others in batches, and not using individual ids??

For the fromObectType abd toObjectType try using names instead - ex. crm/v4/associations/deal/line_item/batch/read
