# Transactions

Endpoint for transactions

## Get Transactions

 - [GET /transactions/customerId/{customerId}](https://dev.triggloyalty.com/openapi/transactions/gettransactions.md): Returns all transactions for a member.

## Create transaction

 - [POST /transactions](https://dev.triggloyalty.com/openapi/transactions/addtransactions.md): Endpoint used for inserting transactions into OIP. 

It is recommended to send in a list/batch of transactions instead of sending multiple single transactions.
The maximum recommended items per batch is around 400 transactions/items.

{% admonition type="info" name="Returns" %}
To make a transaction be processed as a return, you have to do the following:
  * Set the transactionType field on item level to 'RETURN'
  * Set the quantity value to a negative value.
