## Get Categories

<mark style="color:blue;">`GET`</mark> `https://api.photoncommerce.com/api/v2/banktxn/`

Send transactions in an array, where each transaction is a string. If there are multiple fields involved in a given transaction string, separate these by a "|" within the same string. \
\
This endpoint returns an array of categorizes, where each element corresponds to the original transactions.\
\
If you require customized categories, please send your categories and data to train and tune the machine learning to banktransactions @ photoncommerce.com&#x20;
