Introduction - Formance Documentation

Welcome to the Formance Platform API reference documentation. This comprehensive guide provides detailed information about all available endpoints, request/response formats, and examples to help you integrate with the Formance Platform.

Before You Begin

The API reference includes an interactive playground that allows you to test endpoints directly from the documentation. There are two ways to use the playground:

Local proxy with fctl - Use the fctl command-line tool to create a local proxy
Direct API calls - Authenticate directly with the Formance Cloud API

Choose the method that best fits your workflow. The fctl proxy method is often easier for development and testing as it eliminates the need for bearer token management.

Using the API Playground

Using fctl Stack Proxy

The easiest way to use the API playground is through the fctl stack proxy command, which creates a local proxy server and handles authentication automatically.

Install fctl

If you haven’t already, install the Formance CLI (fctl) and either log into or create your Formance Cloud account.

Get Organization and Stack Information

You’ll need your organization ID and stack ID to start the proxy server. This information is accessible through the Formance portal at portal.formance.cloud.You can also use the fctl command-line tool to list your organizations, stacks, and regions:

# List all organizations
fctl cloud organizations list

# List stacks for a specific organization
fctl stack list --organization organizationId

Start the proxy server

Run the following command with your organization and stack IDs:

fctl stack proxy --organization=YOUR_ORG_ID --stack=YOUR_STACK_ID --allowed-origins="https://docs.formance.com"

For example:

fctl stack proxy --organization=jdxmvkvwlyib --stack=ycyb --allowed-origins="https://docs.formance.com"

The proxy server will start and you’ll see confirmation that it’s running on localhost.

Test endpoints

With the proxy running, you can now test endpoints from your browser, or from the playground.

No bearer token is required when using the fctl proxy method.
