POS Terminal Management API

This API provides endpoints for managing your point-of-sale (POS) payment terminals. You can use the API to obtain information about a specific terminal, retrieve overviews of your terminals and stores, and assign terminals to a merchant account or store. For more information, refer to Assign terminals. ## Authentication Each request to the Terminal Management API must be signed with an API key. For this, obtain an API Key from your Customer Area, as described in How to get the API key. Then set this key to the `X-API-Key` header value, for example: ``` curl -H "Content-Type: application/json" \ -H "X-API-Key: Your_API_key" \ ... ``` Note that when going live, you need to generate new web service user credentials to access the live endpoints. ## Versioning Terminal Management API supports versioning using a version suffix in the endpoint URL. This suffix has the following format: "vXX", where XX is the version number. For example: ``` https://postfmapi-test.adyen.com/postfmapi/terminal/v1/getTerminalsUnderAccount ``` When using versioned endpoints, Boolean response values are returned in string format: `"true"` or `"false"`. If you omit the version from the endpoint URL, Boolean re

Plan the first integration safely

The access fields below come from the connected directory. Their likely implementation impact is explained without assuming provider-specific behavior.

Authentication

OAuth is reported. Confirm flows, scopes, consent, token lifetime, and refresh rules.

Transport

HTTPS is not confirmed. Do not send credentials or production data until secure transport is verified.

Browser access

CORS is unknown. Treat direct browser access as unconfirmed and test before choosing a client-only architecture.

First-request sequence

  1. Identify the current base URL, version, and endpoint for the use case.
  2. Confirm how credentials are issued and where they may be stored.
  3. Test success, invalid input, throttling, unavailable data, and timeouts.
  4. Record response fields, pagination, caching, and error shapes.
  5. Add monitoring, retries with backoff, and an appropriate fallback.

Questions to resolve before production

Pricing and quotas

Confirm current plans, free-tier limits, overages, and request ceilings.

Endpoint coverage

Check that the operations and response fields match the intended workload.

Reliability

Look for uptime history, a status page, support routes, and service commitments.

Data and privacy

Review retention, licensing, regional processing, and compliance requirements.

Versioning

Confirm the active version, change policy, deprecation window, and migration guidance.

Developer experience

Validate SDKs, examples, error formats, pagination, and test environments.
