This step is optional
Entities are a way to separate your reconciliation and reporting between different parts of your business. Set these up however makes most sense for your company structure; whether that is for different geographies, legal entities or even product lines.
If you don't need entities then you should skip this step.
Create an entity with this request:
curl --location 'https://api.payable.co/organization/entities' \
--header 'x-api-key: API_KEY' \
--header 'X-Idempotency-Key: UID' \
--header 'Content-Type: application/json' \
--data '{
"entity_name": "EXAMPLE"
}'
