Authentication

Overview

POSaBIT uses two different authentication methods depending on the API version:

Version Method Tokens Required
V3 HTTP Basic Authentication Integrator token + Venue token
V1 / V2 Bearer Token Venue API token

V3 Authentication (Recommended)

The v3 API requires two tokens to authenticate each request: an integrator API token and a venue API token.

Both tokens are combined using HTTP Basic Authentication:

Step 1 — Combine the tokens

integrator_api_token:venue_api_token

Step 2 — Base64 encode the combined string

echo -n "integrator_token:venue_token" | base64

Step 3 — Send in the Authorization header

Authorization: Basic {base64_encoded_tokens}

Complete curl example

curl -X GET "https://app.posabit.com/api/v3/info" \
  -H "Authorization: Basic $(echo -n 'INTEGRATOR_TOKEN:VENUE_TOKEN' | base64)" \
  -H "Accept: application/json"
Tip: If you have only an integrator token, you can call GET /api/v3/info with the venue token part blank. This returns a list of all available venues for your integrator with their tokens.

V1 / V2 Authentication (Legacy)

The legacy API versions use a simple Bearer token in the Authorization header:

curl -X GET "https://app.posabit.com/api/v2/venue/customers" \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -H "Accept: application/json"
Note: V1 and V2 APIs will be deprecated. Please migrate to V3 as soon as possible.
