URL POST API v2.6

Create payments from a single URL

A lightweight GET-style API where parameters travel as URL query string. Useful for quick integrations where your system can't easily POST JSON — mail merges, low-code tools, SMS templating.

When to use this

Use URL POST when your system can emit a URL but can't easily make an HTTP POST request — email merges, no-code tools, SMS gateways, or static document templates. Build the URL once, drop it into the template, and every recipient gets a personalised pay-now link.

If you're writing server code, prefer the Payment Service API. It uses form-data POST, which is easier to log, sign, and observe.

Endpoint

GET https://accounts.paytia.com/api/payment_service?X-API-KEY=…&…

The API key travels in the query string as X-API-KEY. Every other field is a standard URL parameter. Don't put live keys in URLs you can't control — use dedicated sandbox keys for templated links, or request encoded keys.

Flows

Basic URL POST Payment

Create a payment from a single URL — no JSON, no POST body, just query parameters. Useful in CRM macros, call scripts, IVR menus, and email templates.

Encoded URL POST

Same as URL POST but with parameters Base64-encoded for safer transport over channels that may strip, mangle, or log plain query-string content.
