Hi community,

I'm trying to create a contact using the Freshsales CRM API, but I'm receiving the following error response:

json

CopyEdit

{ "success": false, "message": "Freshsales API Error (400): Please add a valid account" }

Here is the sample payload I am sending:

json

CopyEdit

{ "contact": { "first_name": "John", "last_name": "Doe", "email": "john.doe@example.com", "mobile_number": "1234567890", "sales_account_id": 202002197374 } }

I'm setting the sales_account_id to an existing account ID (confirmed from the Freshsales UI and API), but still getting this error.

 What I've Checked:

• The account ID 202002197374 does exist in my Freshsales instance.

• I can fetch the account details successfully via the /api/sales_accounts/tid] endpoint.

• The contact payload structure seems valid per Freshsales API docs.

• The API key and domain are correctly configured, and other endpoints are working.

• Tried using both string and number format for sales_account_id.
