Interested in trying Formance Connectivity out? The simplest way is to create yourself a Cloud Sandbox using the Formance CLI.


Formance Connectivity can also be used and installed locally or deployed as a standalone component without bringing the whole Formance Platform to the party.


If you have Homebrew installed on your computer, you can install the CLI by running:

brew install formancehq/tap/fctl

To upgrade an existing installation of the Formance CLI, run:

brew upgrade fctl


Binaries for fctl are available for Linux, macOS, and Windows. You can download the latest release from the GitHub releases page.

# You can use either amd64 for x86_64 or arm64 for ARM
ARCH="amd64"; curl -L -o fctl.tar.gz "$ARCH.tar.gz" \
&& tar -xvf fctl.tar.gz \
&& sudo mv fctl /usr/local/bin \
&& chmod +x /usr/local/bin/fctl \
&& rm fctl.tar.gz


First, you'll need to add the Formance's package repository to your /etc/apt/sources.list:

deb [trusted=yes] /

Then, you can run this command to install Formance CLI:

apt update && apt install fctl

Installation check

You can check that Formance CLI was installed correctly by trying the following command:

fctl version

You should see something like

Version | 0.10.1
Date | 2023-05-11T10:21:28Z
Commit | f5f577ce

If you don't, then recheck the steps above, or reach out to us to ask for help.

Logging In

Finally, you'll need to either log into or create your Formance Cloud account. You can do that from the CLI:

fctl login

This will take you to a page for creating an account or logging in to your existing account.

Creating your first stack

Once you're logged in, you are able to create one stack for free, with as many ledgers as you want. You can do that with the following command:

fctl stack create helloworld

This will create a new stack called helloworld and set it as the default stack for your account. You can check that it was created successfully by running:

fctl stack list
