Create a contract with an owner-side party

In Oneflow, contracts are created between a party that owns the contract, called the owner-side party and other counterparties.

Whether or not the party is the owner-side party is defined by the my_party attribute. Any party that is not the owner-side party is a counterparty. Please, see more in the Party section.



The owner-side party should always be set to company and cannot be individual.

This tutorial shows you how to create a new contract with an owner-side party using the REST API. You will also learn what data elements you’ll need for this and how to obtain them.

Step 1. Obtain necessary information

To run the script described in this tutorial, you’ll need the following data:

x-oneflow-api-token You will only be able to run the script by providing a valid API token. You can create an API token in the Oneflow web application. Find out more in the Authentication section.
x-oneflow-user-email Your Oneflow user account email.
workspace_id The unique ID of the workspace where you want to create your contract. You can find the workspace ID using the workspaces endpoint.
template_id The unique ID of the template you want to use for creating your contract. You can find the template ID using the templates endpoint.
My party
my_party The party that creates the contract - the owner-side (precisely one.)
participants[array] The owner-side party participant (at least one.) There can be maximum of 29 owner-side party participants.
email The email of the owner-side party contract participant. Note that the email must belong to an active user in your Oneflow account.

Step 2. Run the code

Replace the values of the parameters in the following command with the actual data from your account and run it:

curl --location --request POST '' \
--header 'x-oneflow-api-token: API_TOKEN' \
--header 'x-oneflow-user-email: USER_EMAIL' \
--header 'Content-Type: application/json' \
--data-raw '{
