API Basics

Modernbanc API is located at

It offers simplicity of REST while offerring benefits you'd expect from GraphQL:

  • All get multiple objects endpoints support pagination and filters
  • For all get endpoints you can include only the fields you want.
  • You can ensure one operation never runs twice (important for payments!) by using idempotency keys.


For all workspace-related endpoints please attach x-workspace header with identifier field of your workspace.

For objects that support environments (have environment_id in them) also make sure to attach environment identifier in x-environment header.

For example to list accounts in test environment you'd send a request like below:

curl --request GET \
  --url ''
  -H 'Authorization: ApiKey YOUR_API_KEY'
  -H "x-workspace: acme"
  -H "x-environment: test"
