Yes. Openline offers a reseller and integration API for partners:

  • Catalogue endpoints — list destinations, plans, prices.
  • Order endpoints — create orders, retrieve eSIM QR / activation codes.
  • Usage endpoints — check remaining data and days.
  • Webhooks — activation, expiry, top-up events.

Auth is via API key or OAuth 2.0. Docs live at openline.com/api. Public availability is by application — email ask@openline.com to request access.

Still stuck?

Reach Openline support 24/7 through any of these channels:

When you write in, include your purchase code (the OL-… code we emailed you) and, if the eSIM is already installed, its ICCID (Settings → Cellular → tap the Openline line). That's enough for us to find your plan and diagnose without back-and-forth.
