One compounding pharmacy API instead of a portal and integration per pharmacy

</>

Telehealth brands that integrate pharmacies one by one end up maintaining a separate portal, API and status format for each; the fix is a multi-pharmacy router with one API. AffinityRx is that router: one integration reaches 15+ vetted compounding pharmacies, takes about 1 day of dev work, and your developers can place a test order the same day. Live approval comes on request, with support replies in under 10 minutes.

Why one API fixes the multi-portal mess

AffinityRx replaces N pharmacy connections with one, so a telehealth brand adds pharmacies without adding engineering work.

Every direct pharmacy integration brings its own identifiers, status names, validation rules and release schedule. Three or four of them become a small network to operate, and staff still log into separate portals for the gaps. AffinityRx gives one login, one invoice, one order history and one support contact across 15+ pharmacies, and the API normalizes statuses and webhooks so your code handles one format. When a pharmacy is backordered, automatic failover moves the order to your next favorite within 1–2 minutes with no extra code. Read more in multiple pharmacy portals.

How the integration works

An AffinityRx integration goes from a Test key to a Live order in six steps, and most teams finish the build in about a day.

  1. Get a Test key.Sign up at platform.affinityrx.com and confirm the key with GET /v1/account.
  2. Read the catalog.List pharmacies, catalog items, shipping options and prescribing options to build the prescription form.
  3. Preview and create.POST /v1/order-previews resolves defaults; POST /v1/orders creates a draft with 1 to 20 prescriptions for one patient, or use POST /v1/order-batches for up to 20 orders.
  4. Sign and submit.Your platform authenticates the clinician and collects signing intent, then calls POST /v1/orders/{orderId}/sign-and-submit with an idempotency key.
  5. Follow fulfillment.Receive signed webhooks for acceptance, shipment, delivery and exceptions.
  6. Go Live.Request Live approval; AffinityRx verifies NPI and state license and approves as soon as it's requested. Use a separate Live key and webhook endpoint.
curl --request GET \
  --url https://api.affinityrx.com/v1/account \
  --header "Authorization: Bearer $AFFINITY_API_KEY" \
  --header "Affinity-Version: 2026-09-28"

Switching from RxRelay, LifeFile or a direct pharmacy

AffinityRx moves your existing data for free, so switching doesn't mean re-entering patients.

The AffinityRx account executive handles a free bulk import of patients, order history and active refills from RxRelay, LifeFile or a direct pharmacy. Clinics need no documents to start; the steps are book a demo, preload the $5,000 credit, get a login, enter NPI, place a test order, then a real order. See getting started.
