Subscriptions

Create a subscription

Create a new subscription.

Consumption plans:

meter.type may be smart or analog
customer.vat_id is optional
intended_start_date may be any future date; a date in the past is corrected to the next possible date, and when omitted, the next possible start date is used
previous_supplier may be set to cancel the customer’s existing contract
product_orders may order a smart meter or §14a EnWG grid fee reductions, if the plan supports them

Requests that break one of these rules are rejected with 400 BAD_REQUEST and a message naming the violated rule. Feed-in plans are only available from the 2026-05-27.curie API version onwards; requesting one returns 400 BAD_REQUEST.

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json

The subscription to create

plan

string

required

Plan ID

Example:

"pln_mi4f0oda6x9m7gcsvjk0ole1"

next_possible_start

boolean

required

If set to false we will request the cancellation of the previous supplier / grid operator signup to the date provided in intended_start_date. If set to true we will request the next possible date.

Example:

true

previous_supplier

string

ID of the previous supplier, possible to obtain via /suppliers. Only supported for consumption plans.

Example:

"mp_mi4f0oda6x9m7gcsvjk0ole1"

change_reason

enum<string>

Why the customer signs up at this address: switching supplier at an address they already live at, or moving in. A move-in is registered with the grid operator as such and no cancellation is sent to a supplier found at the address.

Available options:

supplier_change,

move_in

Example:

"supplier_change"

intended_start_date

string<date>

Intended start date of the subscription. Must be a date in the future. For feed-in plans it must be the first day of a month, at least one month in the future; when omitted, the next possible production start date is used.

Example:

"2024-01-01"

lead

string

Lead to track attribution of the subscription

Example:

"lead_mi4f0oda6x9m7gcsvjk0ole1"

product_orders

object[]

Array of additional product orders. Each item has a 'type' and may include an additional object with the same name as the type for its details. Only supported for consumption plans: §14a EnWG does not apply to feed-in, and feed-in requires a smart meter before signup. From API version 2026-09-08.gauss, ordering the same product twice is rejected with 400.

Show child attributes

Example:

[
  { "type": "smart-meter" },
  {
    "type": "14a_enwg",
    "14a_enwg": { "module_1": true }
  }
]

metadata

object | null

Metadata of the subscription. Store any type of information, custom to your needs. E.g. the user_id of your in-house user. Restricted to 10KB.

Example:

{
  "utm_source": "google",
  "utm_campaign": "campaign_name",

Response

The created subscription details

object

enum<string>

required

Type of the object, always 'subscription'

Available options:

subscription

string

required

Unique identifier for the subscription

Example:

"sub_rocbrf1u5e48mm0reeqoag90"

plan

string

required

ID of the plan

Example:

"pln_ctj3tjzc7dywznuw1dy80lb3"

customer

string

required

ID of the customer

Example:

"cus_a8n8ol7yd4h0wohx824f0bui"

household

string

required

ID of the household the subscription belongs to. A household groups the contracts at one metering point: one consumption subscription at a time, plus the feed-in subscriptions on that same meter. It belongs to one customer and stays the same when they cancel and sign up again. A separately metered device, such as a heat pump with its own meter and consumption subscription, is a household of its own, so one customer at one address can have two.

Example:

"dom_k2m9x4qpz7w1c8v3n6b5t0ry"

address

string

required

ID of the address

Example:

"adr_a7gurqkul8lzzsy1pf9p9388"

meter

string

required

ID of the meter

Example:

"mtr_azk4zue2ijx4ff1dbjt14m5h"

payment_method

string

required

ID of the payment method

Example:

"pm_adc9utqqpcp7tx054l7vg56s2"

status

required

Status of the subscription

Available options:

pending,

active,

ended

Example:

"active"

estimated_usage

number

required

Estimated yearly usage in kWh, provided by the customer in the checkout.

Example:

2500

created_at

updated_at

required

number

string | null

Human-readable identifier for the subscription

Example:

"4X44EMKX"

start_at

Timestamp when delivery was started / will start

Example:

"2024-03-14T12:00:00Z"

terminated_at

Timestamp when delivery was terminated

Example:

"2024-03-14T12:00:00Z"
