I'm integrating a Southeast Asian API into my app.

API: Postmark
Provider: Postmark (ActiveCampaign)
Auth: requires an access token (sign up: https://postmarkapp.com/developer)
Pricing: paid
Base URL: https://api.postmarkapp.com
Important note: Fast transactional and broadcast email with Message Streams, templates, inbound processing and webhooks. Paid with a trial. Global, works for MY.

Source: Postmark (ActiveCampaign) (https://postmarkapp.com/developer)
Source type: Provider API or developer docs
Endpoint type: Provider API base URL
Integration difficulty: Needs token
Last checked: 2026-06-13
Production caveat: Keep credentials server-side and confirm current limits, pricing, and webhook/error behaviour in the provider docs.

Help me set up the correct onboarding/authentication path and make the first valid request ~ explain exactly where credentials go and what must happen before production.
