If you have a single organization, any space you create will be automatically associated with that organization. If you’re an admin or an owner in multiple organizations you need to pass the ID of the organization with the
X-Contentful-Organization header that you want to create the space in.If you are on our latest pricing model and have plans attached to your spaces, creating a new space via the API will assign the smallest available plan to it. If you’ve reached your limit of free spaces and have no payment details on file, you won’t be able to create more spaces until you add payment details.
