This endpoint is used to find similar transactions to the source transaction. Similar transactions are determined based on transactions with similar descriptions & amounts to the source transaction.

There will not be any duplicate transactions in the response.

Use the exclude_source query parameter to toggle whether the endpoint returns the source transaction in the response. By default it will.

For example if there are no similar transactions to transaction A:

exclude_source = true

The response will contain 0 transactions

exclude_source = false or not present (default)

The response will contain 1 transaction, that being the source transaction A
