Stripe: Create a Connection Token

← Terminal operations · Get started

Operation stripe.postterminalconnectiontokens

Provider route: POST /v1/terminal/connection_tokens. Alter supplies the connection’s credentials and routing.

Call through Alter

Install @alter-ai/sdk @alter-ai/stripe with npm, or alter-sdk-stripe with pip. Supply your connected customer’s grant ID and the arguments described below.

import { App } from "@alter-ai/sdk";
import { StripeIntegration } from "@alter-ai/stripe";

async function execute(input: Parameters<StripeIntegration["terminal"]["postTerminalConnectionTokens"]>[0]) {
  const app = new App({ apiKey: process.env.ALTER_API_KEY! });
  try {
    const provider = new StripeIntegration(app, { grantId: process.env.PROVIDER_GRANT_ID! });
    const call = await provider.terminal.postTerminalConnectionTokens(input);
    const result = await call.wait();
    return result.bodyJson();
  } finally {
    await app.close();
  }
}

import os
from alter_sdk import App
from alter_sdk_stripe import StripeIntegration

async def execute(arguments):
    async with App(api_key=os.environ["ALTER_API_KEY"]) as app:
        provider = StripeIntegration(app, {"grant_id": os.environ["PROVIDER_GRANT_ID"]})
        call = await provider.terminal.post_terminal_connection_tokens(arguments)
        result = await call.wait()
        return result.body_json()

Schemas

Create a Connection Token — response body

Field	Type	Presence	Description and constraints
$	object	Root	A Connection Token is used by the Stripe Terminal SDK to connect to a reader. Related guide: [Fleet management](https://docs.stripe.com/terminal/fleet/locations)
location	string	Optional	The id of the location that this connection token is scoped to. Note that location scoping only applies to internet-connected readers. For more details, see [the docs on scoping connection tokens](https://docs.stripe.com/terminal/fleet/locations-and-zones?dashboard-or-api=api#connection-tokens). Maximum length: 5000
object	string	Required within parent	String representing the object's type. Objects of the same type share the same value. Known values: terminal.connection_token
secret	string	Required within parent	Your application should pass this token to the Stripe Terminal SDK. Maximum length: 5000

Policy, approvals and errors

SDK function policy ID: stripe.postterminalconnectiontokens. Catalog operation: PostTerminalConnectionTokens. Rules can name either ID; function rules distinguish managed calls and conservatively cover raw calls sharing the route. Existing grant permissions and policy rules apply. wait() returns an immediate result or waits for a required approval; it never approves the request itself. Persist the approval ID to resume after a restart.

Provider errors retain their response; JSON decoding raises ProviderAPIError for provider failures. ManagedOperationError identifies contract/input/retention errors. See error handling and provider-specific behavior. Sensitive input may be refused before approval storage. A decoding error never resubmits a write.
