When you utilize our Transactions product, you will receive a transactions category within the personal_finance_category field. In order to ensure you are receiving categories within a /transactions/get response, you will need to set the include_personal_finance_category field to true in your /transactions/get request. Here's an example using cURL:
curl -X POST https://sandbox.plaid.com/transactions/sync \
-H 'Content-Type: application/json' \
-d '{
"client_id": String,
"secret": String,
"access_token": String,
"cursor": String,
"count": 250,
"options": {include_personal_finance_category: true}
}'
For a comprehensive list of personal finance categories, please refer to this taxonomy csv.
Note: All implementations are recommended to use the newer personal_finance_category taxonomy instead of the older category taxonomy supported by our /categories/get endpoint.
