I am using Hubspot CRM API to create tickets in batch. I was to set Source property of each ticket to Email.
But I didn’t find any property for Source in CRM API.
Refer: Accounts Dashboard | HubSpot
Let me know if there any more properties to send in request apart from following.
{
“hs_pipeline”: “support_pipeline”,
“hs_pipeline_stage”: “open”,
“hs_ticket_priority”: “HIGH”,
“hubspot_owner_id”: “910901”,
“subject”: “troubleshoot report”
}
Hey, @MaheshV 
To confirm, you can add additional properties into your request. Here’s how I did it:
I added the property and value to my request—make sure to use the internal values and not the label—in my case source_type and MY_CAT
My request:
curl --request POST \
--url https://api.hubapi.com/crm/v3/objects/tickets \
--header 'authorization: Bearer NOPE' \
--header 'content-type: application/json' \
--data '{
"properties": {
"hs_pipeline": "0",
"hs_pipeline_stage": "1",
"hs_ticket_priority": "HIGH",
"hubspot_owner_id": "198670650",
"subject": "troubleshoot report",
"source_type": "MY_CAT"
}
}'
My response:
HTTP 201
{
"id": "999396896",
"properties": {
"createdate": "2022-07-14T16:08:40.033Z",
"hs_all_owner_ids": "198670650",
"hs_lastmodifieddate": "2022-07-14T16:08:40.033Z",
"hs_object_id": "999396896",
"hs_pipeline": "0",
"hs_pipeline_stage": "1",
"hs_ticket_id": "999396896",
"hs_ticket_priority": "HIGH",
"hs_user_ids_of_all_owners": "10233975",
"hubspot_owner_assigneddate": "2022-07-14T16:08:40.033Z",
"hubspot_owner_id": "198670650",
"source_type": "MY_CAT",
"subject": "troubleshoot report"
},
"createdAt": "2022-07-14T16:08:40.033Z",
"updatedAt": "2022-07-14T16:08:40.033Z",
"archived": false
And we can see in the CRM that the ticket was created, and the Source was included as expected 
Have fun coding! —Jaycee
Thanks Jaycee,
You’re a legend. The custom property was already there, I thought it it HS property.
After reading your answer looked for the Ticket Property > Source and found it !!
You made my day. Thanks.
Have a nice day.
